Now over four decades old, this 1976 Bicentennial 6-coin set was the most popular ever released. For the first time, three different U.S. coin designs honored a single event — the Bicentennial of the Declaration of Independence. Three different artists created these unique designs for the first generally-issued U.S. coins to bear a double date, 1776-1976. Its special reverse engravings include the Drummer Boy quarter, Independence Hall half dollar and Liberty Bell/Moon dollar. The finest quality double-struck proofs are housed in an official U.S. Mint plastic case.
