Went through my first box of halves in a few weeks over the weekend. Came away with 1 silver, 1 clad proof, 1 Costa Rican coin, and 1 yet to be determined coin. I believe it's a Greek coin, but I'm not positive. Can anyone give any info about the foreign coins? Thanks!
The Greek coin is 75% copper, 25% nickel. Mintage of about 20 million if I recall correctly. Not a rare date, but might sell for a buck or two as a curiosity.
