One proof Bicentennial coin in silver clad and lacking a mint mark, similar to the dollar in the prototype set given to President Ford, is known. This piece supposedly came from a cash register drawer at the Woodward & Lothrop department store in Washington, D.C. Thomas K. DeLorey, who was then a reporter for "Coin World", spoke to the discoverer and was suspicious of the story, thinking it more likely the coin was surreptitiously obtained from the government. He declined to question the origin then, fearing it might be seized and, therefore, not available to numismatists. The piece brought almost $30,000 by private sale in 1987.
