You used to be able to get uncleaned late Roman bronze coins from the Balkans for about a buck apiece in the early 2000s, so I’d guess they’d be maybe $3-5 each now. Then you get the fun of very carefully removing the encrustations to reveal the coin underneath. You generally ended up with a coin worth about what you paid for it, but it was fun.

You still can. The Balkans is pretty widely known as a major center for trafficking looted antiquities, including coins.
