In numismatics, coins with minting mistakes have a special allure. For collectors, these inadvertent production errors transform common coins into exceptional jewels. Even the tiniest coins may result in massive payouts, as seen by the recent $850,000 sale of two uncommon mistake dimes.
What makes these mistake dimes so expensive, how they became numismatic symbols, and what to look for if you’re expecting to find one will all be covered in this book.
The Interest in Error Coins
In addition to being uncommon, minting faults are highly prized for their distinctiveness. Unlike conventional coins that follow stringent design guidelines, error coins are distinguished by defects never intended to occur. Collectors believe these flaws from missing mintmarks to doubled dies make them unique and frequently valuable.
1968-S No-S Roosevelt Dime Proof
The 1968-S No-S Proof Roosevelt Dime is a magnificent illustration of how a minor error may provide enormous value. The San Francisco Mint, renowned for minting proof coins with a “S” mintmark beneath the date, produced this dime.
Nevertheless, the “S” mintmark is absent from this piece, a minting blunder that was overlooked until after manufacturing.
What Makes It Worth It?
Because there are so few of these mistake coins, they are extremely uncommon. Its great value is driven by its rarity and the immaculate condition of some surviving coins.
A perfect 1968-S No-S Proof Dime attracted enthusiasts worldwide when it sold for over $400,000 at a recent auction. It is a true numismatic jewel for those fortunate enough to possess one.
No-S Proof Roosevelt Dime, 1975
The 1975 No-S Proof Roosevelt Dime is even more uncommon than the 1968 version. This proof coin was inadvertently minted without the “S” mintmark, much like the 1968 version.
The fact that only two known specimens of the 1975 No-S Proof Dime makes this inaccuracy even more remarkable. Due to its high rarity, it is one of the most sought-after coins ever produced.
Auction Price Breaking Records
This rarity caused it to fetch one of the highest dime auction prices ever. A 1975 No-S Proof Dime sold for an astounding $450,000 at a recent auction. Because of its rarity and almost flawless state, it is a genuine gem in numismatics.
Why Do These Error Dimes Occur So Seldom?
These proof dimes are extremely expensive since they lack the “S” mintmark. Mintmarks aid in identifying the production location, and proof coins are usually prepared with exceptional care for collectors.
It is highly uncommon for a minting fault, such as a missing mintmark, particularly on proof coins meant for accuracy. The coin’s historical and artistic significance and its rarity add to its appeal and high value.

Why Collectors Prefer Error Coins
Error coins are unique because they are mishaps that never leave the mint. Their individuality adds interest for collectors by providing a narrative about the manufacturing process.
These errors, including a misaligned die, a doubled design, or a missing mintmark, transform common coins into unique rarities. Coins such as the 1968-S No-S Proof Dime and the 1975 No-S Proof Dime are highly sought after, as seen by their high auction values.
Collectors also love the excitement of finding mistake coins in circulation or inherited collections. Even if there is little probability of discovering one, the prospect keeps the quest going.
