I have seen ths coin a few times on coin sites, and got the chance to buy one, it is a very nice 1ounce proof Libertad, but i do not find any information about the 5 rings above the head of liberyty. From years ago i did not thought i had anything to do with the Olympic games but i could be wrong. It must be an aftermarket but the counterstamp is made very well. Who has more information about this coin , why and where it is minted?
