Coin collecting has long been a pursuit of history enthusiasts and investors alike. Among the most coveted treasures are error coins—those rare pieces that, due to minting mistakes, become highly valuable. In 2024, three modern error dimes have particularly stood out, each fetching prices exceeding $25,000.
1. 1975 No-S Roosevelt Dime
The 1975 No-S Roosevelt Dime is a remarkable rarity. Intended for inclusion in proof sets produced at the San Francisco Mint, these dimes should bear the “S” mintmark. However, a few were mistakenly struck without this mark. Only two such specimens are known to exist.
One of these elusive dimes was sold at auction in 2019 for $456,000. More recently, in October 2024, the second known example was auctioned for an impressive $506,250.
2. 1968 No-S Proof Roosevelt Dime
Another significant error is the 1968 No-S Proof Roosevelt Dime. Proof coins from the San Francisco Mint are expected to feature the “S” mintmark. In 1968, a small number of proof dimes were erroneously struck without this mark.
These coins are exceedingly rare, with fewer than 15 examples known. High-grade specimens of this error coin have been valued upwards of $25,000, with top-graded pieces fetching even higher prices at auction.
3. 1982 No-P Roosevelt Dime
The 1982 No-P Roosevelt Dime represents a unique error in modern coinage. This was the first instance where circulating coins from the Philadelphia Mint were intended to bear a “P” mintmark.
Due to a minting oversight, some dimes were released without this mark. While many were produced, they are still valuable today, with high-grade examples reaching up to $1,500.
Top 3 Modern Error Dimes Over $25,000
| Coin | Description | Auction Price (2024) |
|---|---|---|
| 1975 No-S Roosevelt Dime | Missing “S” mintmark; only two known specimens | $506,250 |
| 1968 No-S Proof Roosevelt Dime | Proof coin without “S” mintmark; fewer than 15 known | $25,000+ |
| 1982 No-P Roosevelt Dime | Circulating coin missing “P” mintmark; high-grade examples | Up to $1,500 |
Understanding Mint Errors and Their Value
Mint errors occur due to various factors during the coin production process. The absence of a mintmark, as seen in the dimes mentioned, can result from a die being improperly prepared or a mintmark punch being omitted. Such errors are rare, especially in modern minting where quality control is stringent, making these coins highly desirable to collectors.
The value of an error coin is influenced by its rarity, demand, and condition. Coins in pristine, uncirculated condition (graded as Mint State) command higher prices. The historical context and the story behind the error also add to a coin’s allure and value.
Tips for Aspiring Collectors
- Research: Familiarize yourself with known mint errors and their characteristics.
- Examination: Use magnification tools to inspect coins for anomalies, such as missing mintmarks or doubling of designs.
- Authentication: Seek professional grading services to certify the authenticity and condition of potential error coins.
- Networking: Engage with coin collecting communities, attend coin shows, and consult reputable dealers to enhance your knowledge and collection.
Modern error dimes like the 1975 No-S, 1968 No-S Proof, and 1982 No-P Roosevelt Dimes exemplify the intrigue and value that minting mistakes can bring to numismatics. Their rarity and the stories behind their creation captivate collectors and investors, driving their market value to impressive heights.
As 2024 has demonstrated, the allure of these error coins continues to grow, making them prized possessions in any coin collection.
