Mint errors are the hidden treasures of the coin-collecting world, turning ordinary coins into extraordinary finds. In some cases, a tiny mistake during production can create a rare and valuable coin worth tens of thousands of dollars. This is precisely what happened with four special dimes that are now worth a combined $100,000. Let’s delve into the fascinating story behind these error coins and why collectors are willing to pay such staggering sums for them.
1. The 1968 No-S Proof Roosevelt Dime
One of the most sought-after error dimes is the 1968 No-S Proof Roosevelt Dime. Proof coins are typically struck with a high level of detail and are intended for collectors, often bearing a mintmark indicating their origin. However, a small batch of 1968 proof dimes from the San Francisco Mint was mistakenly struck without the “S” mintmark. Only a few examples of this error exist, making these coins incredibly rare. Pristine specimens of this dime have sold for over $20,000 at auction.
2. The 1975 No-S Roosevelt Dime
Another famous mint error is the 1975 No-S Roosevelt Dime. Similar to the 1968 error, this proof dime was struck without its expected mintmark. What makes this coin even rarer is that only two confirmed examples are known to exist, earning it legendary status among collectors. A high-grade 1975 No-S dime has fetched upwards of $450,000 in past auctions.
3. The 1982 No-P Roosevelt Dime
The 1982 No-P Roosevelt Dime is unique because it’s the first circulation coin to feature a missing mintmark. These dimes were struck at the Philadelphia Mint but accidentally omitted the “P” mintmark. While not as scarce as the 1968 or 1975 dimes, this error is still highly valuable, with some examples selling for $500 or more in mint condition.
4. The 1999 Wide AM Roosevelt Dime
While most error dimes involve missing mintmarks, the 1999 Wide AM Roosevelt Dime stands out for its unusual reverse design. This error coin features a wider spacing between the “A” and “M” in “AMERICA.” Although not as valuable as some no-mintmark errors, high-grade examples of the Wide AM dime have sold for thousands of dollars.
Mint errors can transform ordinary coins into extraordinary collectibles, as these four dimes demonstrate. From missing mintmarks to design anomalies, these rare coins capture the fascination of collectors and the imagination of treasure hunters. If you’re lucky enough to spot one of these error dimes in your collection or change, you could be sitting on a small fortune.
FAQ’s:
1. How do I identify a no-mintmark proof coin?
Proof coins are struck with sharper details and a mirror-like finish. If a proof dime from San Francisco (post-1968) lacks an “S” mintmark, it’s likely a valuable error coin.
2. Are all no-mintmark coins valuable?
No, not all no-mintmark coins are rare or valuable. Most circulation dimes from Philadelphia lack a mintmark and are not considered errors.
3. Where can I find error coins like these?
Check your pocket change, old coin jars, or proof sets purchased from the U.S. Mint. Error coins can also be found at coin shows or from reputable dealers.
4. How do I determine the value of a mint error coin?
The value depends on factors like rarity, condition, and demand. Professional coin grading services like PCGS or NGC can authenticate and grade your coin for accurate valuation.
5. Should I clean my error coin before selling it?
Never clean a coin, as this can reduce its value. Collectors prefer coins in their original, unaltered state.
