The obverse has a portrait of Martha Washington facing right, while the reverse shows a view of Mount Vernon. Struck in cupronickel-copper (multi-layer composite). Struck from the so-called "nonsense dies" without a specified denomination. Dime-sized and half dollar-size pieces were also produced. USPatterns.com states: "It is believed to be the first metallurgical trials [circa 1965] using the current cupro-nickel clad planchets. The Martha Washington obverse was designed by Edward R. Grove and the reverse is by Philip Fowler." Grove's initials are beneath Washington's shoulder.
