The following metallurgical trial piece is believed to have been struck in 1999. It uses the 2nd set of Martha Washington dies which was also used on some quarters J2116/P2082 and the strikings on the golden dollars J2185. Examples were struck as follows: Reeded Edge J2183. Intermittently reeded edge 5 or 6 reeds per block J2184 as shown below. It is believed that this intermittent reeding was an attempt to help the blind differentiate this from the quarter dollar. Martha Washington dollars on the Sacagawea dollar planchets are also known with this intermittent reeding. For more on this, click here. The Martha Washington design has become the U.S. Mint's 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, Schuler AG and Olin Brass Corporation. Because of this, it is not known if the piece above was struck inside or outside the Mint. Photo courtesy of Mike Byers.
