Twenty years ago, I was buying cash coins for
Twenty Cent each.
I had no idea if they were genuine or not. However, at that price, that issue did not worry me very much.
I also hadn't a clue at that time how to identify them
!I have since taken all of them to a good dealer friend of mine who has been in the business with ancient coins for at least 30 years. His opinion was, that they were all genuine.
I bought a copy of Schjoth and subsequently identified them all. As such, they would have a current market value typically of between $5 and $10 each. I have most dynasties and Emperors, with about half of the Reign Titles, covering around the last 2,000 years.
