One of the best ways to detect a fake seller on eBay is to look at the other items he is selling. If they are selling a lot of single unique pieces they are more likely to be genuine. If they are selling a lot of the same looking pieces and they are likely fakes. Because it is very difficult to produce hundreds of different unique fakes while it is very easy to produce hundreds of simple fakes.

But if you're not a purist and you just want to build a nice collection of very good reproductions - Greek , Roman , Russian , German/Austrian coins and medals , you name it - , you're the lucky one . For about € 2 per coin you have all the choice there is....
Thumb's up for another fine and helpful episode. I'm off to find your earlier one on the topic. Much as I always feel an odd sense of unease at seeing a lovely old coin anachronistically entombed in one of those grading service lucite sarcophagi, the fakes out there are getting SO good and becoming SO hard to detect, even with special equipment, that I hate to concur that I almost understand why it's quickly becoming necessary to certify them....especially with costlier ones.
This is why I find hammer struck coins among the most interesting the way they deformed as the hammer hit the metal it always deforms it in someway that no modern machine does and how each coin is different
Often on eBay you will see too many amazingly preserved coins either being passed over, or if sold, an exact twin appearing in a future (often the very next) auction. Study the bidding history and avoid coins that are pictured poorly, ie blurred.
Take a close up picture of a real coin and the fake using a camera phone and flash. Zoom in,and you will see the cast coin looks like the surface of the moon compared to the struck coin
Thanks so much, Leo. As always, super interesting and useful. Perhaps you could consider making a video on the third century 'barbarous radiates' in the near future.
What are you talking about? You can get an Ides of March for a few hundred dollars! You can't even find those coins at all on MA Shops or Vcoins. Ebay is great for coin collecting!😂
Cast fakes aren't the problem. It's the struck coins made with fake dies which have ethier been milled or edm'd which are the really tricky ones to tell. Almost impossible to tell if they're gold coins.
I would say struck fakes made with transfer dies (which are made from original coins) may be quite dangerous because they are struck and the style is correct, although you sort them out by checking the edge, or rather the border, near the rim... but some modern fakes made by advanced microcasting techniques are even more dangerous.
Thank you very much for your information. I came to your site for my Kushan Indian gold coin and Bactrian Greco-Roman Gold coins. Easy to detect the fake!
Couple more things now I've watched the whole video. Cast fakes made with lossless wax casting won't have edge casting seems although may have a mark where the wax spru is joined. With lossless wax casting the plaster is put into a vacuum chamber to minimise bubbles and when the gold or silver is added a jewelers/dentists centrifuge is used in order to completely fill the mould. More modern advances in 3d resin printing means you can now cast in wax for lossless casting and with some relatively simple maths the size and volume can be modified to take into account the shrinkage in casting this can all be done in the 3d modelling software. These fakes won't fool the Harland J Burke's of the world but they will fool experienced collectors who aren't aware of modern technology. Also you can "cast" dies as well which although is expensive (usually you want to do it in 12k-14k gold -but saying that you can always melt down your dies afterwards. Numismatic forgery by Charles m Larsen is a fantastic book but it could do with an update with modern techniques.
It's still quite difficult to replicate genuine patina. And a cast coin will ring duller than a struck coin. But you are correct that state of the art counterfeit coins require better detection methods.
It ŵould be amazing if you could also make a video analyzing flan or struck forgeries with artificial patinas and weathering. To me, they are the most dangerous kind...
Thank you so much! Although, I wish I would have seen this before I bought five coins on eBay. After I received them, I'm going to take them to my local coin place so they can do some metal testing on them to see if any of them are actually real.
Rotary investment casting would probably be very hard to detect. I've worked with investment casting where my fingerprints came through on the final piece.
Please make more videos about fake coins and fake precious metals. Like how much do they actually make per coin at each quality level? How many fakes are made a year and are entering the inventories of dealers? What are high value fakes that have sold for big monies? Please more like this. Thank you and have a good one
One of the first reasons is that unlike a mold for casting, the dies for striking must be hard metal. This means several steps that require expertise far beyond mold making. Another reason is that once you have acceptable dies with sufficient hardness you need the correct flan or planchette and there's some effort needed to get the diameter and thickness correct. Then there's the striking process. Which could use a press or hammer. For accurate replication it's a two person job. The flan is heated to anneal the metal and placed on the stationary, lower die and the upper die held in alignment and struck one or more times. Misalignment will produce a reject. Compare the above to prepare a mold, melt the metal and pour into the mold then when cool separate the mold halves. Much simpler and therefore cheaper, so very commonly done.
Thanks for posting this document. l have a Thasos Tetradracm , a very beautiful coin, yet a cast fake l´m sure, more and more now. Well, c` est la vie..
Depends on how much you paid for the coin. Silver isn't _that_ expensive and is easy to work with. Take it to a coin shop and see what they think about your coin's authenticity. Experts can generally tell fakes pretty easily
Is there any way I could send you a link to a coin currently for auction or get your opinion on a specific ebay seller? I've seen the other videos on fakes, and you are by far the best resource I can think of to check to give an opinion
Sorry, I dont offer this kind of personal advise, I hope you understand that if I answered all of you people's requests, I wouldnt have time for anything else. I have plenty of tutorials and there is quite a bit of material online that should provide enough content for you to study and develop an eye for detecting fakes.
Personally I believe I have never bought a fake coin from an Auction house. SEEING possible fakes on catalogs is another thing. Yes, I have seen fakes on some occasions, and voiced my concerns to the seller.
@@ClassicalNumismatics Cheers! Excited to get my first order of ancient coins in hand from a few auctions over this last weekend. Your videos definitely guided me over the last 2 years so thank you very much.
will laser sintered coins become an issue with detecting counterfits? especially now that 3d scanners are getting more detailed than their silicone counterparts?
It's kind of interesting to me that cast coins are a common way to fake a coin. Historically they struck the coins because it was cheap. If the goal was perfection they would have removed the flashing, and struck the coins dead center. remelting any with tears/defects. Counterfeiting wasn't even a real worry (so long as the coin was made of the right purity of gold/silver). It honestly seems worlds easier to me to make a coin the historical way than to try and cast it.

I accidentally bid on a fake the other day. It wasnt a scam or anything, just they said the time period it was from so I assumed it was real but further down they mentioned it was a "modern collectable item". Always read it all before bidding because I won and couldnt back out of paying for it! Its a septimus severus with his wife on one side and caracalla on the other by the way.
Reproductions of any coins-ancient or modern-sold in the United States must be clearly marked as a reproduction, copy or replica under terms of the _Hobby Protection Act of 1973._ If yours is not, you may still have legal recourse, no matter how well hidden in the auction text or how it may be stated that it is not genuine. It MUST be struck or cast into the coin itself.
@BilgemasterBill I bought some coins the other day from a souvenir shop, I figured they were just tokens, but they are heavy even for their size, I'll have to check that again, as they were less than ten dollars. Seems like they would not sell something as a real coin seeing as we are in a small capital city...
I dont buy ancient coins from any seller with less than 500 transactions and 100% positive feedback. Ebay accounts with only a few transactions have little to lose and could vanish overnight.
But bothering me most are those fake coins that were actually struck, please make another epsode to explain how to spot those fake coins produced using ancient method with real pure silver and gold.

Sometimes it can be hard to tell the difference,between a grainy surface on a genuine coin, from the grainy or porous surface on a cast fake.
This is why I find hammer struck coins among the most interesting the way they deformed as the hammer hit the metal it always deforms it in someway that no modern machine does and how each coin is different

Thanks for the informative video, is it so hard to make fake struck coins? If so can you please explain why?
Try to make one and find out
I think it’s more expensive than hard, making metal molds for mass producing anything is extremely expensive and time consuming process. :)
One of the first reasons is that unlike a mold for casting, the dies for striking must be hard metal. This means several steps that require expertise far beyond mold making.
Another reason is that once you have acceptable dies with sufficient hardness you need the correct flan or planchette and there's some effort needed to get the diameter and thickness correct.
