* 1975-1976 Bicentennial reverses were minted. These coins are dated 1776-1976; none were individually dated 1975 or 1976.
The double date of 1776-1976, with a temporary Bicentennial reverse, was carried on the Quarter (Colonial Drummer), Half Dollar (Independence Hall), and Eisenhower Dollar (Liberty Bell/Moon). The Eisenhower Dollar (1971-1978) carried the Bicentennial Reverse in 1975 and 1976.
Life Span: The approximate life span of a coin is 30 years. Mutilated Coins: United States Coins no longer fit for circulation are classified as "uncurrent" or mutilated. -Uncurrent coins are coins that are worn yet recognizable as to genuineness and denomination, and are machine countable. Uncurrent coins are redeemed by the Federal Reserve Banks, then forwarded to the Mint for disposition. -Mutilated coins are coins that are chipped, fused and not machine countable. Mutilated coins are only redeemable through the United States Philadelphia Mint facility. All uncurrent or mutilated coins received by the Mint are melted and reused in the manufacture of coinage strips.
