Rare 1975 No‑S Roosevelt Dime Worth Over $500K – Collector’s Identification Guide

Rare 1975 No‑S Roosevelt Dime Worth Over $500K: The Roosevelt Dime has been a cornerstone of American coinage since 1946, honoring President Franklin D. Roosevelt. While most examples are common and circulate widely, certain rare varieties have become legendary in the world of numismatics. Among them, the 1975 No S Roosevelt Dime stands out as one of the most valuable modern coins, with pristine specimens selling for more than $500,000. This guide explores the history, rarity, and identification tips for collectors seeking to understand this remarkable coin.

Historical Background

The Roosevelt Dime was introduced to replace the Mercury Dime, with a design by John R. Sinnock. The obverse features Roosevelt’s portrait, while the reverse depicts a torch flanked by an olive branch and an oak branch, symbolizing liberty, peace, and strength. By the 1970s, proof coins were struck at the San Francisco Mint, identified by the “S” mint mark. The absence of this mark in 1975 created one of the rarest modern coin varieties.

The 1975 No S Roosevelt Dime

In 1975, a small number of proof dimes were mistakenly struck without the “S” mint mark. These coins were never intended for circulation and were only discovered in proof sets. Because so few exist, they are considered one of the rarest modern U.S. coins. High-grade examples certified by professional grading services have sold for over $500,000, making them a crown jewel for collectors.

Why It Is So Valuable

Several factors contribute to the extraordinary value of the 1975 No S Roosevelt Dime:

  • Extreme rarity: Only a handful of examples are known to exist.
  • Proof quality: These coins were struck with special dies for collectors, giving them exceptional detail and finish.
  • Historical significance: The error highlights the importance of mint marks in coinage history.
  • Collector demand: Modern rarities attract intense interest from both seasoned numismatists and investors.

Identifying the 1975 No S Dime

Collectors must carefully examine proof sets to identify this rarity:

  • Selling cleaned or damaged coins as “uncirculated.”
  • Misrepresenting proof coins as rare varieties.
    Collectors should buy from reputable dealers and seek certification before investing in high-value pieces.
