I bought these during a vacation to Greece back when I was 11 and most avid in my coin collecting. It was one of those stands in a marketplace that sold them cheap. I remember being suspicious, but not enough not to buy a few.
I've had them in my coin box since then and recently started digging through it, and now I'm just curious, I want to know.
They look rather sloppy, as if I made them myself with soft metal and a stamp (and didn't bother to aim).*** Moved by Staff moved to a more appropriate forum. ***
