Been there, done that. Coin shop took it back after NGC verification came back as “not authentic.” I’m not a novice, yet I could not tell it was fake. Btw it was an old seated liberty.
The Naxos tetradrachm that was sold by CNG as Becker and that was mentioned in first post is not a Becker fogery but a 100 % match (Galvano) to the authentic specimen in British Museum in London and the other Galvano in Yale university ! So someone really paid 2500 Dollar + fees for a worthless Galvano of an authentic coin. And the cited Becker forgery Hill 21 is of course from different dies (last three pictures show real Becker forgery Hill 21), see for example the hair of Sileno´s Maybe anyone wants to notify CNG ^^ Brithis Museum Galvano sold wrongly as Becker, picture 1 https://www.cngcoins.com/Coin.aspx?CoinID=359330 Authentic mother in British Museum in London, identical dies, flan shape, centering, wear etc. Pictures 2+3 https://www.britishmuseum.org/resea...x?assetId=379318001&objectId=1294613&partId=1 And the other identical Gavlano in Yale university and the made same mistake to describe as Becker although they have a real Becker Picture 4 https://artgallery.yale.edu/collections/objects/173350 And here is a real Becker hill 21 , look for example for hair of Sileno´s, which is very different Picture 5 https://www.cngcoins.com/Coin.aspx?CoinID=373960 Picture 6 is out of hill And Yale university real Becker https://artgallery.yale.edu/collections/objects/171647 Picture 7 I have sadly noticed that several coins sold as forgeries by famous forgers were galvanos from authentic coins or not from this forger etc.
That's a very interesting coin. Its style is VERY different from Rome mint issues of Faustina. Moreover, this coin is not known to RIC, BMCRE4, RSC, or Cohen. It IS cited by Strack, however. The BMC has two specimens of this coin in gold, and they look VERY different in style. Here's one of them (the British Museum website is having issues). If an example wasn't cited by Strack nor sold at The New York Sale, I'd say it was fake. The most intellectually honest thing I can say about it is that it was not struck by the authorities at the Rome mint. I'm leaning toward modern forgery -- I wouldn't purchase it and I'm a Faustina I enthusiast. I suppose it's possible that it was from a branch mint somewhere or an ancient imitation.
