The factory's Alibaba page offers fifty different ancient coin types. I have not inspected any of them personally but a coin from the same dies as the one in the photograph above was published in 2007 by a noted Bulgarian scholar as genuine (I think... can't read Bulgarian).
This manufacturer claims to employ over 100 people at a factory at Qiuaid Town Industrial Estate, Yinzhou District, Ningbo City, Zhejiang Province, China. Mr. Ruifang Wang is the contact.
Strangely the site claims to offer the coin in the photo for twenty cents, but with a minumum order of 10000 pieces. I have been wanting this particular fake since 2005 and only three have turned up on the market. If anyone does manage to contact the seller I'd love to purchase some specimens of this particular replica.
According to the seller's Alibaba page, “Quzhou Fake Ancient Coins Factory is established in year 2000. We can make all kinds of fake ancient coins such as Ancient Greek, Roman, Biblical, Byzantine and Persian coins. All these coins are made from zinc alloy or brass material with antique silver or gold plated. We can produce fake coins and also metal gifts or metal souvenirs.”. This is apparently not a clandestine manufacturer, the seller warns “Illegal usage is not allowed. Please leave us alone if you want to use it for cheating.”
