How This Rare Error Occurred
The Roosevelt Dime was first introduced in 1946 to honor President Franklin D. Roosevelt, recognizing his efforts in public health advocacy, especially through the March of Dimes campaign. Typically, proof dimes from the San Francisco Mint carry an “S” mint mark, signifying their production location.
However, in a surprising turn of events, a limited number of proof dimes minted in 1970 were mistakenly struck without the “S” mark. These coins were originally included in proof sets meant for collectors, but over time, some inadvertently entered circulation. The oversight turned this particular dime into one of the most sought-after errors in U.S. coinage.
Key Identifying Features of the 1970-S No S Proof Dime
If you suspect you have one of these valuable dimes, look for these distinguishing features:
- Missing Mint Mark: The absence of the “S” above the date on the obverse side is the primary giveaway.
- Proof Finish: Unlike standard dimes, proof coins exhibit a highly reflective, mirror-like surface with well-defined details.
- Limited Mintage: Only around 2,000 of these coins were ever produced, making them an extreme rarity.
How Did These Coins Enter Circulation?
Despite being intended for collectors, some of these dimes made their way into everyday transactions due to:
- Lack of Awareness: Many original owners or their heirs may not have recognized their rarity and mistakenly spent them.
- Estate Sales & Liquidations: Rare coins often get mixed into collections that are later sold or inherited, unintentionally entering circulation.
This means that checking your loose change could lead to an unexpected and valuable discovery!
