The 1968 No S Dime is a rare U.S. coin worth up to $18,000 at auction. This dime is unique because it lacks the “S” mintmark that usually shows it was made at the San Francisco Mint. A special error during production left this mintmark off, making the coin extremely valuable and highly collectible. Read on to learn what makes this coin so valuable, its unique features, and how you can spot one.
Why the 1968 No S Dime is So Valuable
The 1968 No S Dime is part of a rare group of coins called “No S Proof Dimes.” Unlike most proof dimes from 1968 that have an “S” mark showing they were made in San Francisco, this version was minted without it due to a mistake. Only a few coins like this were made, which makes it very rare.
According to Heritage Auctions, this dime is one of the top 100 Greatest Modern U.S. Coins and ranks as the third most valuable U.S. modern coin in the Schechter-Garrett reference. This rare piece holds a special place in the world of coin collecting because it’s both unique and hard to find.
Unique Appearance of the 1968 No S Dime
Collectors love this coin not just for its rarity but also for its beautiful appearance. The 1968 No S Dime has a smooth, glossy surface with a rare powder-blue patina—a soft blue shine—on both sides. This soft color makes it stand out even more and adds to its collectible value.
An example of this coin graded at PR67 Cameo by the Numismatic Guaranty Corporation (NGC) had clear details and a glassy surface, with a small aqua spot on Roosevelt’s nose. Tiny details like these make each coin unique, adding to its appeal for collectors.

Low Numbers Mean High Value
Another reason for the 1968 No S Dime’s high value is the small number of these coins in high grades. Only a few coins from 1968 without the “S” mintmark exist, and only one of these is graded at PR67 Cameo, with just one other graded even higher. Because there are so few high-quality examples, this dime can fetch thousands of dollars at auction.
The coin’s construction also makes it special: it’s made of 75% copper and 25% nickel on a copper core, weighing only 2.27 grams. These materials make it durable and add to its appeal as a modern collectible.
How to Spot a 1968 No S Dime
If you’re checking dimes from 1968, look carefully for the “S” mintmark. The absence of this mintmark is key to knowing if you have a rare 1968 No S Dime. If you think you may have found one, it’s wise to have it examined and graded by a professional service like NGC or PCGS, which can verify its authenticity and determine its value.
