This year is marked by the appearance of the Bicentennial quarter, half dollar and silver dollar. Proof examples were made in Philadelphia which lack the "S" mintmark. Supposedly, at least 2 complete sets were made. The only example known today is of the silver dollar J2164/P2088 According to the Coin World Comprehensive Catalog & Encyclopedia, it was discovered in a cash register at Woodward and Lothrup Department store in Washington D.C. in mid-1977. It is said to weigh 383.25 grains instead of 350 grains, thus it was struck on a 40% silver planchet. Photo courtesy of Bowers and Merena. Go to Previous Page Or Next Page
