The 1975 Roosevelt Dime: A Brief Overview

The 1975 dime belongs to the Roosevelt Dime series, introduced in 1946 to honor President Franklin D. Roosevelt, who passed away in 1945. Featuring Roosevelt’s portrait on the obverse and a torch flanked by an olive and oak branch on the reverse, these dimes are composed of a copper-nickel clad (75% copper, 25% nickel) with a reeded edge. In 1975, the U.S. Mint produced dimes at three facilities:

Philadelphia Mint: 585,673,900 dimes, no mint mark.
Denver Mint: 313,705,000 dimes, marked with a “D.”
San Francisco Mint: 2,845,450 proof dimes, marked with an “S.”

Most 1975 dimes, especially those from Philadelphia and Denver, are common and worth only their face value (10 cents) in circulated condition. However, a specific error in the San Francisco proof sets has made a tiny number of 1975 dimes incredibly rare and valuable.

The $505,000 Dime: The 1975 No-S Proof Roosevelt Dime

The 1975 dime that commands prices upwards of $505,000 is the No-S Proof Roosevelt Dime, a coin so rare that only two examples are known to exist. This coin was part of the 1975 proof sets produced by the San Francisco Mint, which were sold to collectors for $7 each. Proof coins are specially struck with polished dies and planchets, resulting in a mirror-like finish and sharp details. All San Francisco proof dimes were intended to bear an “S” mint mark, but due to a minting error, two dimes were struck without it.

Why Is the No-S Dime So Valuable?

The value of the 1975 No-S Proof Dime stems from its extreme rarity and historical significance:

Scarcity: With only two authenticated examples, it’s one of the rarest modern U.S. coins. No additional No-S dimes from 1975 have been reported since their discovery in the late 1970s.
Minting Error: The absence of the “S” mint mark was an unintentional mistake, likely due to a die without the mint mark being used during proof striking. Such errors are highly prized in numismatics.
Condition: Both known examples are in pristine proof condition, graded highly by services like the Professional Coin Grading Service (PCGS). One is graded PR67, and the other PR68, with the latter valued at up to $575,000.
Provenance: The coins have a compelling story, including being held in a bank vault for decades by an Ohio family, adding to their allure.

In October 2024, one of these dimes sold at auction for $506,250, setting a record for this coin type, as reported by GreatCollections. The other sold for $456,000 in 2019, demonstrating consistent high demand among collectors.

How to Identify a 1975 No-S Proof Dime

If you’re wondering whether your 1975 dime is the valuable No-S variety, here’s what to look for:

Proof Characteristics: The coin must be a proof strike, identifiable by its mirror-like surface, frosted design elements, and exceptional clarity. Regular circulation dimes lack this reflective quality.
No Mint Mark: Check below Roosevelt’s neck on the obverse. If there’s no “S” mint mark, it could be a candidate. Note that Philadelphia dimes from 1975 also lack a mint mark, but they are business strikes, not proofs.
Source: The No-S dimes were found in 1975 proof sets, typically housed in hard plastic cases. If your dime is loose or circulated, it’s unlikely to be the rare variety.

Common Misconceptions

Many people mistake regular 1975 Philadelphia dimes (no mint mark) for the rare No-S proof dime. Philadelphia produced over 585 million dimes without mint marks for circulation, and these are worth only 10 cents in worn condition. Even in mint state, they fetch modest prices ($0.15 to $3). The key difference is that the valuable No-S dime is a proof coin, not a business strike.

Other Valuable 1975 Dime Varieties

While the No-S Proof Dime is the star, other 1975 dimes can also hold value due to errors or high grades:

S Over S Proof Dime: Some 1975 San Francisco proof dimes have a doubled “S” mint mark, where one “S” is punched over another. These are less rare but can be worth $800 in PR69 Deep Cameo condition.
Full Band Designation: For Denver (“D”) dimes, those with fully struck horizontal bands on the torch (Full Band designation) are more valuable. A 1975-D MS67+ Full Band dime is valued at $1,250.
High-Grade Coins: Uncirculated 1975 dimes, especially those graded MS65 or higher, can fetch $7 to $30, depending on the mint mark and condition.

How to Determine Your Dime’s Value

If you suspect you have a valuable 1975 dime, follow these steps:

Examine the Coin: Use a magnifying glass to check for the mint mark and proof characteristics. Compare it to images of proof coins online.
Preserve Condition: Avoid cleaning or handling the coin excessively, as this can reduce its value. Store it in a protective holder.
Get It Authenticated: Submit the coin to a reputable grading service like PCGS or NGC. Authentication is crucial for rare coins like the No-S dime, as counterfeits exist.
Consult an Expert: Contact a numismatist or auction house like GreatCollections for an appraisal. They can guide you on selling options if the coin is valuable.

Where to Sell a Rare 1975 Dime

If you confirm your dime is a No-S Proof, consider these selling avenues:

Auction Houses: GreatCollections, Heritage Auctions, or Stack’s Bowers specialize in rare coins and can maximize your sale price. The 1975 No-S dime that sold for $506,250 was auctioned by GreatCollections.
Coin Dealers: Reputable dealers can offer fair prices, though auctions often yield higher returns due to competitive bidding.
Online Platforms: Avoid generic platforms like eBay for such rare coins, as scams are prevalent. Use platforms with numismatic expertise.

The Story Behind the No-S Dime

The 1975 No-S Proof Dime has a fascinating history. Discovered in 1977 by California collector Fred Vollmer, the coins were part of proof sets purchased directly from the Mint. In 1978, an Ohio family bought one for $18,200 (equivalent to ~$90,000 today), storing it in a bank vault for over 40 years. After the family’s brother passed away, three sisters inherited the coin, which was auctioned in 2024. This narrative of family legacy and hidden treasure adds to the coin’s mystique.

Why Coin Collecting Matters

The allure of the 1975 No-S Dime highlights why coin collecting captivates millions. Numismatics combines history, art, and the thrill of discovery. Errors like the No-S dime remind us that even small mistakes can create treasures. As Ian Russell of GreatCollections noted, “If you have old proof sets at home, check the dime.” The possibility that a $7 proof set could contain a half-million-dollar coin keeps collectors searching.

In Summary

Is your 1975 dime worth $505,000? Unless it’s one of the two known No-S Proof Roosevelt Dimes, the answer is likely no. However, the story of this rare coin serves as a reminder to inspect your collection carefully. Most 1975 dimes are worth only their face value, but errors, high grades, or proof characteristics can elevate their price. If you own a 1975 proof set, take a moment to check the dime for that missing “S.” You might just uncover a numismatic gem that could change your life.
