In the world of coin collecting, certain coins become extraordinarily valuable due to minting errors, and the 1975 “No-S” Roosevelt dime is one of the most prized examples. Recently, one such rare dime sold for over $500,000 at auction, making headlines and sparking interest in this highly elusive coin.
Only two examples of the 1975 “No-S” dime are known to exist, and if you happen to find one, it could mean a windfall.
What Makes the 1975 No-S Dime So Valuable?
This dime’s rarity and value stem from a missing “S” mintmark, which typically designates coins minted in San Francisco. The U.S. Mint inadvertently produced this error on a handful of 1975 dimes, leading to a few coins leaving the mint without this identifying mark.
Known as proof coins, these dimes were specially struck and included in proof sets, meaning they were never intended for general circulation. Proof coins have finer detail, making them distinct from standard coins meant for daily use.
How to Identify the 1975 No-S Proof Dime
Collectors searching for this coin should look within 1975 proof sets, as it would be nearly impossible to find in everyday circulation. Here are some identifying features:
- Absence of the “S” mintmark: On the 1975 No-S dime, you won’t find the “S” near the year on the coin, an anomaly that drastically boosts its value.
- Proof finish: This coin has a sharper, mirror-like finish due to its proof quality.
- Preserved condition: Since proof coins weren’t intended for circulation, they often have minimal wear.
Historical Sales and Current Value
The 1975 No-S dime is extremely rare. The first known example sold for $18,200 in 1978 (around $90,000 in today’s value) and recently resold at an auction held by GreatCollections, fetching $506,250. This price reflects its rarity and collector demand.
The whereabouts of only two 1975 No-S dimes have been confirmed, leaving collectors intrigued by the potential existence of others.

Why Are Mint Errors So Valuable?
Coins with minting errors are incredibly valuable to collectors because they represent unique variations from standard mint production. The U.S. Mint carefully controls coin quality, so errors, especially in proof sets, are exceedingly rare.
For this reason, mint errors like the 1975 No-S dime are considered gems by numismatists, elevating their value at auction.
Tips for Aspiring Coin Collectors
If you’re interested in coin collecting, start by examining proof sets and learning about the distinct characteristics of proof coins. Professional grading services can help verify authenticity and assign a grade, which can significantly impact a coin’s value.
