This Corelay® token, produced by the Polymetallurgical Corporation (PMC) of Attleboro, Massachusetts, has been presented as a coinage option to mints throughout the world, including the U.S. Mint. PMC produced 500 of these tokens specifically for presentation at the XIX Mint Directors Conference held May 27-30, 1996, in Warsaw, Poland. Representatives from the United States Mint were in attendance at the conference. According to PMC, Corelay® "consists of a magnetic core material surrounded by a non-magnetic or slightly magnetic alloy selected for its durability, anti-tarnish properties, color and formability. Coinage made from Corelay system allows the magnetic core to be virtually invisible to the naked eye, giving the coin a monolithic appearance while allowing high degree of detectability by coin validators."

The Corelay® technique was pitched to the U.S. Mint as a viable option for the dollar coinage program. It was tested by the mint and was found to have a high degree of security. For various reasons, Corelay® was not selected as the material used for the golden dollar. Currently, there is no coinage using the Corelay® system.
