I found this in the ocean at Aruba. About the size of a silver dollar and has $5 on the reverse along with a lizard, flamingos, and the Island of Aruba. The obverse just has The President's Club and a stylized PC in the center. Not sure what the metal is....not brass, copper, or any precious metal as it's starting to corrode away. I see many companies that have a "president's club" for those who meet a certain sales quota, but, I'm not sure why they would have a coin made with $5 on it. I would think a casino would make them out of a better metal, but, who knows? I tried looking it up on Tokencatelog.com but, didn't get a hit. Anyone know what it is for sure?
