In 1975, the United States began minting Eisenhower dollars with the dual dates 1776-1976, which mark the occasion of the United States bicentennial. The 200th birthday of our nation’s founding sparked gala ceremonies all around the United States on July 4, 1976, and the lead-up to the special birthday prompted the United States to memorialize the event on the dollar coin, which bore a special design featuring the moon superimposed by the Liberty Bell.
There were two styles of the bicentennial dollar reverse; these are called Type I and Type II dollars. Type I dollars exhibit thick, sans-serif lettering, while the Type II pieces show more refined, serif-style letters. The copper-nickel clad dollar coins feature both styles, but the 40 percent 1976 dollars were minted and released only with the Type I design, which was struck in 1975.
11,000,000 uncirculated 1976-S 40 percent silver dollars were minted while 4,000,000 proof versions of the 1776-1976 S silver dollar were produced. In general, when silver content is worth around $20 per ounce, uncirculated 40 percent silver bicentennial dollars cost around $14 and proofs carry a $20 price tag.
While you can buy silver bicentennial dollars individually, they are available in special, 3-piece uncirculated and proof sets that were assembled by the United States Mint. These sets include the 1776-1976 quarter and half dollar, which also display special bicentennial-themed designs.
