This find highlights the value of checking proof sets thoroughly. Few rare coins are ever found outside of collections, and with numismatic prices increasing all the time, it’s never a more advantageous time to examine your coin collection.

What is the 1975 No-S Roosevelt Dime?

The error 1975 No-S Roosevelt Dime is an extremely rare proof coin that was accidentally minted without the presence of the “S” mint mark. This was done at the San Francisco Mint, which produced all its coins as proof coins that were supposed to bear the “S” mark. Yet, at least two dimes in the proof sets were minted without it, which makes this one of the most uncommon coins in recent U.S. history.

Understanding the Minting Error

In 1975, the United States Mint stamped more than 2.8 million proof sets, but no more than two dimes had no “S” mint mark. Unlike standard Philadelphia-minted dimes, these pieces feature a proof finish, having been specially crafted for collectors’ purposes, characterized by mirror surfaces and more prominent details.

Mint mistakes such as these are very rare, so any fresh find is a numismatic giant event. These mistakes usually happen when a mint mark die is accidentally left out or replaced while making the coins.

How to Spot the 1975 No-S Roosevelt Dime

Locating a 1975 No-S dime is all about noticing details. Here’s how to inspect:

Step 1: Check for Proof Features

• A true No-S dime features a mirror-like appearance with frosted motifs. If your 1975 dime appears to be dull or circulated in look, it’s probably not the rare proof edition.

Step 2: Inspect the Mint Mark

• San Francisco proof dimes would feature an “S” mint mark below Roosevelt’s neck.
• If your proof coin lacks a mint mark, it might be the rare error coin.
• If your 1975 dime is a normal coin without a mint mark, it’s from Philadelphia, and not unusual.

Step 3: Check the Source

• These dimes were discovered in proof sets, rather than in general circulation.
• If you own a 1975 proof set, inspect the dime thoroughly.
• Proof sets are in plastic capsules, usually with five or six coins (cent, nickel, dime, quarter, and half-dollar).

Step 4: Check the Coin

If you think you have a No-S dime, submit it to a professional grading service like:

• PCGS (Professional Coin Grading Service)
• NGC (Numismatic Guaranty Company)

They will authenticate its legitimacy and give it a grade, which can make a big difference in its value.
