It is illegal to sell ancient coins, so if you even MENTIONED an interest in ancient coins they would literally pack up and leave. They were that worried about being instigated in ancient coin sales.

However, as my wife and I walked up the monster mountain to the Parthenon we were approached at least a dozen times by kids and young males trying to sell fake and fantasy coins like these. They had their stories down pat and it was actually entertaining to listen to them tell their stories about how the rare and valuable coins came into their possessions. They also usually added that they needed the money for a sick mother.

I always asked them questions and gave them the equivalent of about $2 after they told their story, more for a break from continuing to climb than for any other reason. Plus, it's nice to be nice and I like to think that's one of the reasons we had such a great month in Greece.
