Imagine finding a seemingly ordinary quarter in your coin jar, only to learn it’s worth up to $7 million. That’s the story behind the rare 1975 “No S” Proof Bicentennial Quarter, a numismatic treasure that continues to capture the fascination of collectors across the globe. In this article, you’ll discover what makes this coin so valuable, how to identify it, and tips for turning rare finds into real profit.
What Is the $7 Million Bicentennial Quarter?
The Bicentennial Quarter, issued to commemorate 200 years of U.S. independence, usually features the dates 1776–1976 and a colonial drummer design. However, in an extremely rare instance, a 1975 proof version missing the “S” mint mark from the San Francisco Mint was accidentally released. That missing “S” transforms an ordinary proof into a once-in-a-generation rarity.

Why Is This Coin Worth Millions?
Several factors contribute to the staggering value of this quarter:
1. Extreme Rarity
Only a few known pieces exist. Mistakes like this—especially on proof coins—are exceptionally uncommon.
2. Proof Quality
Proof coins are not for circulation. They’re produced with high precision and mirror-like finishes. That quality, paired with a minting error, raises collector interest.
3. Cultural and Historical Appeal
Released during the U.S. Bicentennial celebration, these quarters hold deep historical significance, increasing emotional and collectible value.
4. Demand in Auctions
Bidding wars have been known to break out at major auctions for this coin. With few in existence and many collectors eager to own one, prices climb fast.
How to Spot the Rare “No S” Bicentennial Quarter
If you think you might be sitting on treasure, here are key steps to examine your coin:
Step 1: Look for the Mint Mark
- Normal proof quarters from 1975 have an “S” for San Francisco.
- The rare coin has no mint mark at all—a result of a die setup error.
Step 2: Examine the Finish
- It should have a glossy, mirror-like surface—a sign of proof quality.
- If the coin looks like a proof but lacks the “S,” that’s a major clue.
Step 3: Confirm the Dual Date
All Bicentennial quarters feature “1776–1976”—a must-have detail for identification.
Step 4: Condition is Critical
- Coins with no scratches, minimal wear, and full luster are worth more.
- Avoid cleaning it—this can lower its value significantly.
Step 5: Get It Appraised
- Contact a professional numismatist.
- Use certification services like PCGS or NGC for official grading.
Why Do Minting Errors Like This Happen?
Even with modern technology, minting mistakes still occur due to:
- Human Error: Incorrect die setup can skip mint marks.
- Mechanical Failures: Equipment may malfunction.
- Quality Control Lapses: Especially under production pressure, some coins slip through checks.
In the case of this rare quarter, a proof die without the “S” mint mark was likely used in error before being caught—resulting in a few rare pieces entering the collector market.
What Should You Do If You Find One?
- Handle With Gloves – Prevent skin oils from damaging the coin.
- Avoid Cleaning It – Cleaning lowers its market value.
- Get It Verified – Use PCGS or NGC for authentication.
- Store Securely – Keep it in a hard case, away from moisture.
- Consider Selling – Use reputable auction houses or dealers specializing in rare coins.
