This Corelay token was produced by the Polymetallurgical Corporation
(PMC) of Attleboro, Massachusetts, and was presented as a coinage option to mints throughout the world.
PMC produced 500 of these tokens specifically for presentation at the XIX Mint Directors Conference held on
May 27-30, 1996, in Warsaw, Poland. According to Polymetallurgical Corporation, 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 however,
Corelay® was not selected as the material used for the golden dollar. Currently, there is no coinage using the
Corelay® system.
