The 1975 No S Roosevelt Dime Proof is one of the most sought-after error coins in U.S. numismatics
Typically, proof coins are struck with an "S" mintmark, indicating they were produced at the San Francisco Mint.
However, in a rare minting error, a small batch of dimes in 1975 was accidentally struck without the “S” mintmark, making them incredibly rare and valuable.
Only a handful of these No S Roosevelt Dimes are known to exist, and they are highly prized by collectors.
The error was discovered after the release of the 1975 proof sets, leading to immediate excitement within the numismatic community.
In terms of value, the 1975 No S Roosevelt Dime Proof can fetch anywhere from $25,000 to $100,000 depending on its condition and market demand.
Because of its rarity, this coin is considered a top-tier collectible, especially for those looking to complete a Roosevelt dime collection.
