I will tell you another thing. If someone paid $100,000 for an Alexander the Great drachma they got screwed. They are selling from $200 to $400 on Ebay.
I saw some of those in a coin store last year. It was unusual because they looked really good, and there were about 5 of them. Usually you only see 1 or 2 a year, unless you go looking for them. They are used for necklaces here in the US. Salvor6 has got the price of them about right. About 1 in 5 are barbaric copies, and 1 in 5 are just plain forgeries.
