For the Bicentennial of the Declaration of Independence, Congress authorized a special Liberty Bell/Moon reverse engraving, suggesting 200 years of American progress. The Bicentennial coins (quarters and half dollars also) are the only ones double-dated in U.S. Mint history. The superb proof minting features deep-etched frosted engravings that contrast with dazzling mirror-finish backgrounds. Far fewer of the 40% silver proofs were struck than silver Brilliant Uncirculated issues.
