In my opinion these are definitely fakes, and the seller, jorjscoins, is on Warren Esty's notorious fake sellers list: http://augustusmath.hypermart.net/fakesellers.html Please don't take this as an insult, but you really should heed the advice given in other threads where you were asking about fake coins you had already bought or were considering and spend the extra money to buy from established dealers and auction houses instead of random eBay sellers.
Advice noted... The thread was "authentic or Fake"? Since they are obvious fakes how are they doing it with bronze? The patina? is common I notice Saxby's has many coins with this patina too
Cast replicas with chemically manufactured patinas. There are various mixtures that can be used to create similar patinas, occasionally they're even used on authentic coins that have had their patina stripped while cleaning. I'm not going to list any of them here but if you search around various coin supply shops online you will see some of the premade ones.
I responded above but did not vote in the poll, because the poll choices are too limited. "Cast" suggests cast from a genuine coin. However, the style of these coins is completely wrong. At best, they are casts of coins struck from fake dies.
This is a forgery (David Sear caught this baby when I sent it to him for authentification) => yah, those forgers are pretty slick with the ol' re-patina thingy
I think the second is a definite cast of a fake, but likely both are. I've seen quite a few fakesellers lately selling similar casts of either cast or die-struck/pressed fakes.
I added the David Sear certificate (sorry about the crappy photo) => he explains his reasons in the text
Exactly! We are not here to insult anyone except, perhaps, people who sell fakes to beginners. Some of us have been posting here for several years and other places for years before that. The same questions come up regularly. Some of us, myself included, occasionally have coins that we question and may post them here as well as sending them off to have someone else look at them on occasion in the hope that e will get an answer that we will be able to accept fully in our own minds. Some coins are way past the opinion stage and the only question is what class fake they are. That is where Carausius' comment comes in. There are fakes made from genuine coins, fakes made by casting from fakes, fakes from new dies faithfully copying originals, fantasies made that bear no resemblance to anything genuine ever considered by the ancients and probably a few dozen categories I left out here. You could cut out this collecting of ancient coins and spend the rest of your life devoted to the study of numismatic fakes. I have chosen other branches of the hobby. https://www.cngcoins.com/Coin.aspx?CoinID=319718 The recent CNG sale included the above lot I considered interesting. The 84 coins in the lot were all fake and I suspect judging from the photo there were a number of different types a great deal closer to being deceptive than our quiz coins here. At a little over $2 a coin, buying that group could provide some valuable education. CNG is not known for cheap realizations but if they will sell you a certain fake for ~$2, what do you think the fair market value on the coin would be in bargain outlets? Joe over at Forvm has a great piece of advice: Either know the coin or know the seller. We all get in trouble when we think we do and don't. Here is my advice for gambling on coins: Take the cash you were going to spend on questionable coins and buy Lottery Tickets until you hit the $100 million prize and can afford to buy unquestionable coins in a proper venue. By the time you win the Lottery, you will have had plenty of time to study which sellers are worthy of your business. If I had a spare $1-10 million, I know some people I would feel secure in hiring to spend it on my behalf (for a reasonable fee, of course). This is the best of both worlds satisfying your need to gamble and perhaps even allow you to get some nice coins if you are very, very lucky.
I meant the forgers made a glaring mistake not you. Its easy once a professional points it out to a person.
among many companies who produce patinas on bronze: http://www.sciencecompany.com/Patina-Formulas-for-Brass-Bronze-and-Copper.aspx
But that's precisely what you are doing when you continue to buy coins from questionable eBay sellers. The coins you posted would never have been sold as genuine by a reputable ancient coin specialist. You should buy only from reputable ancient coin specialists until you learn to spot the fakes.
