1946-S Roosevelt Dime: Post-War Collector’s Gem
The 1946-S Roosevelt Dime marked the beginning of the Roosevelt dime series following Franklin D. Roosevelt’s death. Minted in San Francisco, high-grade uncirculated coins are scarce. Coins with sharp details, full luster, and minimal wear can sell for $2,000 to $5,000. Collectors value them for both rarity and their historical significance as the first post-war Roosevelt dimes.

1968-S Roosevelt Dime: Proof Coin Rarity
Issued exclusively in proof sets, the 1968-S Roosevelt Dime rarely reached circulation. These coins feature mirrored surfaces and finely struck details. Proof coins showing subtle doubling on inscriptions like “LIBERTY” or “IN GOD WE TRUST” can fetch $2,000 to $10,000, depending on grading by PCGS or NGC.
1975 “No S” Roosevelt Dime: Modern Numismatic Rarity
A very small number of 1975 proof dimes were struck without the “S” mintmark at the San Francisco Mint. Only two confirmed coins are known, one selling for over $450,000. Missing mintmarks make these dimes exceptionally rare, and professional authentication is recommended immediately.
1916-D Mercury Dime: Key-Date Classic
The 1916-D Mercury Dime, minted in Denver, is a key-date coin with only 264,000 examples produced. Featuring Liberty with a winged cap, it is one of the most celebrated U.S. coin designs. High-grade examples can exceed $100,000, while circulated coins still command thousands of dollars. Collectors see it as an essential piece for Mercury dime collections.
1976 Bicentennial Quarter: Commemorative Collectible
Celebrating America’s 200th anniversary, the 1976 Bicentennial Quarter features dual dates 1776–1976 and a colonial drummer on the reverse. While most quarters are worth only face value, rare variations such as silver proofs, double-die errors, off-center strikes, and mint-state 70 coins have generated collector excitement. Rumors of extremely rare prototypes suggest potential values in the multi-million-dollar range, though no verified sales at that level exist.
