1975 "No S" Proof Roosevelt Dime Value Guide

The 1975 'No S' Proof Roosevelt Dime is one of the most significant and elusive modern error coins in United States numismatics. While standard proof coins from this era were struck at the San Francisco Mint and should bear an 'S' mint mark, a tiny fraction were released without it, creating an instant holy grail for collectors.

What Is 1975 "No S" Proof Roosevelt Dime Worth?

The typical price range for 1975 "No S" Proof Roosevelt Dime is $75,000 - $82,500 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Numerical grade and preservation, as higher-tier proof specimens command the top end of the $75,000-$82,500 range.
• The presence of 'Deep Cameo' or 'Ultra Cameo' contrast between the frosted devices and mirrored fields.
• Market demand and auction provenance, as only two confirmed examples are widely known to exist in the collecting community.
• Certification status by major third-party grading companies to guarantee the coin is not a deceptive Philadelphia mint alteration.

How to Identify 1975 "No S" Proof Roosevelt Dime?

• Verify the coin has a mirror-like proof finish, which distinguishes it from the common Philadelphia business strikes of 1975.
• Inspect the area above the date; an authentic error will be completely blank where the 'S' mint mark is typically located.
• Confirm the coin is housed in an original 1975 Proof Set or has been certified by a reputable grading service like PCGS or NGC.
• Check for the sharp, high-relief details characteristic of the proof die striking process on the copper-nickel clad surface.
