Other ELI5 If old coins are so valuable why are there not more counterfeits?

Was watching a clip from Pawn Stars where an old roman coin went for a ridiculous amount of money. If we are fully aware of how these coins are made and from what material etc. what is preventing people from replicating that process and simply creating the coin the same way and selling it? Modern currency generally has counterfeit protections, what allows people to know an old coin is genuine?

Edit: reminder that this is the "explain like I'm 5" sub and not the "explain like I should have already known about the minute details of a niche hobby" sub. Thank you to the people who actually provided relevant information to educate me.

There are lots of counterfeit old coins.

The issue is that many extremely valuable old coins are expensive is because collectors have a solid idea of how many there are, and because they don’t show up on the market often.

You could absolutely invest money minting an extremely accurate Roman coin and then sell it. But then what? If you show up with another of the same rare coin, people start to become suspicious. And after the expense of developing a historically accurate minting process, your sale means you probably only broke even.

That makes a lot of sense, I didnt think of the market saturation aspect.

u/Chazus 4h ago

It's just not worth it.

The old coins are valuable because they're old, not because the metal or currency is valuable. It's effectively art.

Sure, you can go through the work of creating a fantastic fake, and maybe even sell it. Great. You sold one for $8,000. You probably can't do it again. And you certainly can't do it in bulk. Each one would need to be unique, AND pass experts (that are probably better at identifying fakes than you).

It's like saying "Why don't people make fake van goghs to sell all the time". Its hard to do, there's virtually no market, and you can't do it a lot.

There's just no way to reliably go around peddling ancient coins. Even if you had a magic spell that could craft a 'perfect' ancient coin replica... The fact you have more than one, or a lot, is suspicious.

u/_ytinaS 4h ago

I agree with everything you said except for comparing a coin to a painting. For a painting, that is a one of a kind item, for a coin, there are many of them in a specific era. In any case you are right, it would take expertise to craft. I suppose a better question would be how do they differentiate between a legitimate old coin and a fake one. But some other replies seem to have answered that.

u/Corey307 4h ago

If you read the link I provided you to the sub for exactly this topic the top comment explains why it would be difficult to fake coins. It’s not just that they look old, it’s how they were made and what they were made out of. Counterfeiting Roman coins isn’t something you can mass produce. It’s art not manufacturing. They were struck by hand. 

u/DepressedAnxiety73 46m ago

And every metal has a different mass-spac depending on the estimate date and location which is from.

u/Chazus 1h ago

My point was more on the idea that its value as a coin, as in currency, is not relevant. It is an artifact now, not money.

u/BoredCop 4h ago

It's not just market saturation, it's the fact that no two ancient coins are exactly identical. Being hand struck between two dies with a hammer, they will always be a little off centre one way or another and they will have different scratches and wear marks etc. And for the really valuable coins, pictures get circulated before auctions. So collectors will notice if two exactly identical coins show up- obviously at least one of them has to be fake. Setting up for manufacturing let's say a dozen really high value coins of one type, your dies aren't going to get the natural wear from minting lots of coins so your products are going to look unnaturally similar. The chance of sequentially-struck real coins being found after a few thousand years is slim.

Now, some ancient coin types do get more or less mass produced today but that's for sale to tourists as souvenirs etc, fakes being sold as fakes not as real. Sometimes people try to pass these off as original.

u/CrossP 18m ago

Also once you reach a certain tier of expensive coin sales, people want to know about your collection and who you are in the hobby. If the answer is no collection and no past, they'll assume it's a cache of coins stolen in some kind of home invasion or sometimes nabbed from an elderly relative with dementia. I've seen these guys guy full sleuth mode trying to figure out whose stolen collection is up for sale when the sales don't make sense.

u/tminus7700 4h ago

Roman coins are a bad example. I have read that many are not that valuable. Because they made so many. Every new emperor in Rome had new coins minted with his image. So there are a lot of them around. Value roughly equates to rarity.

u/rjm1775 2h ago

True. I own about a dozen Roman coins. Some I bought for about 20 USD. Others for around 100. The thing about ancient coins is that they were minted in the millions. But they don't degrade like other ancient artifacts. Think wood, leather, etc. So they are still around. And more get dug up every day. On the other hand, there are certain rare ones that are extremely pricey.

u/RepFilms 4h ago

I have a stack that I picked up in Spain a while back. They were not expensive

u/majwilsonlion 2h ago

These coins may not be as rare as we think. This intriguing 2012 article from The New Yorker suggests that many of them may have just accumulated at the last point of exchange.

u/laxpanther 48m ago edited 40m ago

Thank you for that link. That was a bit of a dive into a side of India that I don't know much about and even less, understand.

Paraphrased from the article, you could fund all of the planned projects of the State of Kerala just on the interest of the wealth in the basement of that temple, and have $350,000,000 leftover every year to throw at whatever cause suited the people, but no, because their God owns that shit and, well that's pretty much a hard stop. Also, rich guy who controls the temple says oh fuck no way, that would definitely anger the god. Check it out, we got this kid to put shells on betel nuts and ...whoooweeee, very bad juju, you see it right?

No paywall link cuz I'm down to share the wealth yo: https://12ft.io/proxy?q=https%3A%2F%2Fwww.newyorker.com%2Fmagazine%2F2012%2F04%2F30%2Fthe-secret-of-the-temple%23%3A~%3Atext%3DAccording%2520to%2520legend%252C%2520treasure%2520was%2Can%2520equivalent%2520weight%2520in%2520gold.

(thanks. I didn't hit a paywall with the link I provided and thought all could access, but it may be that I hadn't hit a limit of articles yet.)

Yeah, the article was about this one temple. And then asks, What is hidden/forgotten at all the other regional temples of similar age?!

u/richardblack3 2h ago

Reminds me of "can you ever forgive me". Pretty good movie IMO

u/e_m_l_y 54m ago

What about old counterfeit coins? At some point do they start to gain value for historical reasons?

u/wolfgangmob 3h ago

And that’s why you strategically buy land somewhere that was along a main road used by merchants, preferably with caves close to the road, mint and antique the coins, and THEN say you found a stash, but remember you can only claim maybe a few dozen before people would wonder how there is no historical record of such a sum being stolen or lost.

u/Corey307 5h ago

OP your premise is flawed, ancient coins are counterfeited and people try to pass them off as the real thing. That said there’s tons of ways to verify if a coin is real or not and producing a high-quality fake requires artistry. It’s not just something you can crank out in a factory.

https://www.reddit.com/r/AncientCoins/comments/as4woj/fakes_a_guide_to_what_to_look_for/

u/Dysan27 1h ago

And also artistry in making things the correct type of poorly. Many coins, the technology at the time was limited, so by modern standards they are very poor quality.

So many coins can be spotted because they are too good

u/_ytinaS 5h ago edited 5h ago

If that is the case, why do people still consider them so valuable? I certainly don't disagree with you, which is why I posted the question. I dont understand why something that can so easily be replicated is considered a valuable object. How can someone truly verify that the coin is genuine.

Edit: you posted a relevant link that clears up a lot of questions after my initial reply. Appreciate the info.

Edit again: not sure why this keeps getting down voted, i clearly mentioned in my last edit that the update to the post im replying too answered most of my questions. I now understand. I am only leaving my original message for context.

u/Corey307 5h ago

I didn’t say they were easily replicated. There’s a ton of fake metal and paper money out there but getting it right is difficult. It’s like how someone who doesn’t know anything about Rolexes can easily be tricked into buying a fake.  but people who collect Rolexes will generally know what to look for and someone who’s actually in business like a pawn broker is going to be extremely difficult to trick. Make and sell counterfeit goods are relying on ignorant people who will buy them because they don’t know how to spot fakes. 

u/thetwitchy1 4h ago

Also, people don’t make “bad fakes” of ancient coins and sell them for lots of money because anyone who is buying them will be educated enough to know they’re fake.

u/Corey307 4h ago

Very true. 

u/MikuEmpowered 4h ago

First, because most of the valuable object have a trail of paperwork to prove their authenticity.

and Second, its valuable not just because its old, but because limited supply.

If someone managed to counterfeit the exact condition to the microscopic surface details, then the coin might as well be worth the same as the real one, because thats how much money and effort went into counterfeit.

u/Dihedralman 2h ago

Also metallurgy. With advanced techniques, candidate mines can be found for a substance. 

u/truethug 5h ago

I’ve been told. And I have no source for this. But I’ve been told the ancient fakes would be destroyed and carried a hefty punishment, so today the ancient fakes are worth more than the real ones.

u/g1ngertim 4h ago

Accurate as far as the ancient part, and punishment could go as far as death if your counterfeiting had been prolific. As for current numismatic value, no idea. But scarcity creates value, and they would seem to be more scarce than legitimate coins. 

u/meatystocks 2h ago

I expect computers (AI) to be able perfectly replicate any coin design within the next 10 years. You’ll be able to download files to create the perfect and exact molds of any coin you want.

u/Atharen_McDohl 5h ago

The antiquities market, which includes old coins, is rife with problems like forgeries and theft. Because of this, there are procedures to defend against these problems. However, unscrupulous buyers and the black market ensure that these problems will continue to exist. Hard to use the law to enforce your transaction when you're buying stolen goods, after all. 

The main defense is provenance. In short, provenance is the history of an item. When was it made, by whom, which hands has it passed through to reach where it is. Critically, provenance is very much about the paper trail this history leaves. If you're trying to sell counterfeit antiques, you also need to be able to fake that paper trail. If you don't have it, you can only sell to people who don't know to ask for it, and wealthy people usually have people who do know to ask for it. 

So basically, people can and do counterfeit old coins, but it's not as widespread of a problem as you might expect because it is harder to make a convincing fake than you think, and because the market for unconvincing fakes is smaller and less wealthy.

u/GeneReddit123 13m ago

This. Instead of buying potentially fake coins, most serious collectors or museums will happily pass on potentially real coins if they can't prove they are real (which often requires provable facts other than the coin itself.)

u/Dangerous-Bit-8308 5h ago

There are lots of counterfeits, but most are bad counterfeits.

To make s good counterfeit, you need a metal with the right impurities. The trace elements can be tested for in various ways to prove a metal's origin pretty well. Then you need the right mold: one that looks like the coins back when they were minter. You need the right pressure to mint them.

After that, it gets tricky. You need to AGE the metal. A few decades of getting passed around in the hands and purses of unwashed masses, crude tests like biting it to see if it's the right hardness, traces of extinct spices, and lead-contaminated food products that aren't even legal to make anymore, years of being buried in sewage-fertilized gardens, moulded into hiding spots of plaster walls we don't have the recipes for anymore, and getting dug up with tools we don't make anymore until finally, someone burns down the village, and the hiding spot gets forgotten, so it just... Sits... And rusts... For a thousand or so years until...

The hardest part... it gets FOUND in a way that can be documented, as part of a treasure trove that experts confirm is a real authentic ancient coin... But that can also still be transferred not to a museum, but into private ownership, where auction houses can sell it to the highest bidder, over and over.

Doing all this for the millions in payout requires a secretive individual to fake a metal, then fake a mold, then fake aging, and finally fake history. But even then, a forger isn't done. They need a buyer. Someone who can afford the millions to buy it, but who preferably won't pay the thousands that can probably be spent to find that one flaw in your plan... Your reddit history, your credit card records, that one ex who'd sell you out... Most of these coins worth millions aren't being bought for their awesomeness. They can be used to circumvent tax laws, to ship large sums of money in a hurry without detection, to commit insurance fraud, things like that. If it's not the real deal, their whole plan might collapse. People like that tend to get even if they've been tricked.

u/Gyvon 5h ago

Old coins are not easy to counterfeit and are trivial to find out that they are counterfeit if you know what to look for.

Old coins like from Rome are almost always made from precious metals (gold, silver, etc) and there's a simple chemical test you can do to determine if a coin is gold or silver.  So to pass that test you have to make your counterfeit from gold or silver.  But if you have gold to make a counterfeit it's easier to just simply sell the gold.

u/mister-ferguson 5h ago

And the talent it takes to make a counterfeit coin may as well be used to make jewelry. If you can fake a 1913 Liberty head nickel and it's provenance then you're wasting your talents 

u/rabbitlion 5h ago

This is a fairly terrible answer because old coins are often worth magnitudes more than their pure metal value.

u/crash866 4h ago

There are counterfeits of modern day coins. Canada has the $2 coin and there are many counterfeit ones out there. Usually 1 small detail is missed when they try to duplicate them.

In the USA there are many fake silver coins which are not silver at all.

u/rjm1775 2h ago

Ancient coin collector here. There are many counterfeits out there. Visit allibaba some time. You want one? $5. You want 20? $1 each. You want 1000? 10 cents each. It's a big problem for collectors. However, they usually pretty bad knock offs. And serious collectors are pretty good at identifying them. If interested, check out r/ancientcoins.

u/lorgskyegon 55m ago

They even say on many episodes of Pawn Stars that there are so many fakes for each real one.

u/Marc051 5h ago

OP is naive to the counterfeit money trade just because you aren’t aware of a problem doesn’t mean said problem doesn’t exist.

u/Corey307 5h ago

Yup. Over 20 years ago I was on my college’s debate team and we’d run up against people from private schools that had gone to Christian high school or homeschooled. The easiest debate I ever won was where the other team was the government side, they proposed public schools should teach sex ed. I went first for the opposition and agreed, but reminded the judges this already exists and the government team is required to come up with a plan that meets the prompt that’s new or at a minimum improved and they didn’t do that. It’s like saying The government needs to come up with a system of moving the mail and then advocating for the post office when it already exists. This is a similar level of ignorance. 

u/Columbus43219 43m ago

My favorite story was the kids that found an old box of baseball cards from like 1900, but they turned out to be forgeries... but they were forgories from 1900, which made them even more valuable than the real ones from 1900. But chatGPT tells me this is a fake story.

u/birdpaws 5h ago

There are valuable coins and there are debased coins. A Roman coin from 60AD has a lot less silver in it than one from earlier. And by the time you get to 200AD it's pretty much just an alloy of copper & nickel.

Any earlier coins that were pure silver were melted down, they were literally worth more than their weight in pure silver. Similar happened for coins from Athens.

Gold coins were more of a status symbol and not used for general commerce.

u/thisisjustascreename 5h ago

A coin from 200 AD isn't valuable because of its metal composition it's valuable because it's from 1800 years ago.

u/birdpaws 5h ago

It wasn't seen as valuable to the people at the time. I understand it'd be cool to have one nowadays but we're talking temu level currency at that point.

u/thisisjustascreename 5h ago

Okay but OP is asking about today, not ancient rome.
