I have seen the "Scrooge's first cent" come up for sale occasionally on ebay, but I don't monitor the prices. It may have had a picture of a US cent (or an embedded coin), not a euro coin - but I'm not sure.

The euro coin appears to be an ordinary coin, though, right? Not a commemorative or anything special?

I can see why Disney would want a casino item removed - they have been anti-casino for quite some time.
