The 1968 No-S Proof Dime stands as a testament to the intriguing world of numismatics, where minting anomalies can transform ordinary coins into coveted treasures.
This particular dime, missing the customary ‘S’ mintmark, has captured the attention of collectors and investors alike, with some specimens fetching impressive sums at auctions.
Understanding the 1968 No-S Proof Dime
In 1968, the U.S. Mint produced proof coins at the San Francisco facility, each typically bearing an ‘S’ mintmark.
However, a small number of Roosevelt dimes were mistakenly struck without this mark, resulting in the rare 1968 No-S Proof Dime. These coins were part of proof sets intended for collectors, making their error both notable and valuable.
Rarity and Survival Estimates
The scarcity of the 1968 No-S Proof Dime significantly contributes to its value. Estimates suggest that approximately 12 such coins exist across all grades.
This limited availability places it among the rarest modern U.S. coins, with a numismatic rarity rating of R-9.5.
