Another Martha Washington Test Piece Discovered

This design has become the U.S. Mintís all-purpose design for testing new compositions and planchet sizes both inside the Mint and outside by companies contracted by the Mint including IDX Inc, PMX Industries and Olin Brass Corporation.

This piece is struck with what is believed to be Braille in the obverse fields, and was probably struck by Olin Brass.
