Abstract
A two-component blank suitable for minting into a coin is described. The blank consists of a low-carbon steel core completely encased in nickel. The blank has magnetic properties sufficiently similar to a solid nickel coin of the same size that the minted blank is accepted by magnetic property testing coin discriminating devices which accept pure nickel coins.
