What Makes the 1970-S No S Proof Roosevelt Dime So Special?
The Roosevelt Dime, first introduced in 1946, was created to honor President Franklin D. Roosevelt and his legacy, particularly his contributions to public health through the March of Dimes. Proof versions of this dime, made specifically for collectors, are renowned for their exceptional quality, with mirror-like finishes and sharp detailing. Typically, proof coins from the San Francisco Mint bear an “S” mint mark to indicate their origin.
However, in a rare twist of fate, a small batch of these coins was struck without the mint mark in 1970. This oversight led to one of the most sought-after error coins in U.S. numismatics. While these dimes were originally distributed as part of proof sets for collectors, some found their way into general circulation over time.
Identifying the 1970-S No S Proof Roosevelt Dime
If you think you’ve come across one of these rare dimes, here’s how to identify it:
- Missing Mint Mark: The most obvious sign of this error coin is the absence of the “S” mint mark above the date on the front of the coin.
- Proof Finish: Unlike regular circulation coins, proof coins have a glossy, mirror-like surface and crisp, detailed features.
- Rarity: With only around 2,000 coins believed to have been minted, the 1970-S No S Proof Roosevelt Dime is one of the rarest dimes ever made.
How These Dimes Ended Up in Circulation
Although the 1970-S No S Proof Roosevelt Dime was never meant for circulation, a few of these coins have unexpectedly ended up in the pockets of everyday people. Here are some of the reasons why:
- Lack of Recognition: Many of the original owners may not have known the coin’s rarity, and they might have spent it like any other dime.
- Estate Sales and Liquidations: Rare coins sometimes get mixed in with other items during estate sales, leading to their inadvertent release into circulation.
This means that if you’re lucky, you could stumble upon one of these valuable coins in your change.
