Rare dimes and Bicentennial coins have long fascinated collectors, not only for their historical significance but also for their remarkable market values. Among these, three standout examples collectively amass an astonishing worth of approximately $450 million.
1. 1894-S Barber Dime
The 1894-S Barber Dime is one of the most coveted coins in U.S. numismatics. In 1894, the San Francisco Mint produced only 24 of these dimes, primarily as proofs. The exact reason for such a limited mintage remains uncertain, though some suggest they were minted to balance the mint’s books. Today, only nine specimens are known to exist. One of these dimes fetched $1.997 million at a 2016 auction.
2. 1975 “No S” Proof Roosevelt Dime
In 1975, a rare error occurred at the San Francisco Mint, resulting in a small number of proof Roosevelt dimes being struck without the “S” mint mark. These “No S” dimes are exceptionally scarce, with only two confirmed examples. One such coin was sold in 2019 for $456,000, and another in 2023 for over $500,000.
3. 1976 Bicentennial Quarter Struck on a Gold Planchet
To commemorate the U.S. Bicentennial in 1976, special quarters were minted featuring a unique reverse design. An extraordinary error led to a few of these quarters being struck on gold planchets instead of the standard copper-nickel composition. These rare pieces have fetched staggering sums at auctions, with one reportedly selling for nearly $28 million.
