What Are S-Mint Quarters?
S-mint quarters are U.S. quarters struck at the San Francisco Mint, denoted by the small “S” mintmark. Although the mint was founded in the 1800s, it became well-known for producing limited-run proof and commemorative coins, especially from 1937 onward.
What sets these coins apart is their low production volume and occasional minting anomalies, making some editions incredibly rare—and highly valuable.
Why Are They So Valuable?
Rarity
The primary driver of value in S-mint quarters is rarity. Some years saw extremely limited production, and in some cases, minting errors further reduced the number of quality surviving examples. These limited releases create immense demand among collectors.
Condition & Grade
The condition—or “grade”—of a coin significantly influences its market value. Coins are graded on a 70-point scale, with MS-70 (Mint State) being perfect. A rare coin in mint condition can command a dramatically higher price than one that is worn or damaged.
Special Features & Historical Relevance
Some quarters gain value from their unique designs or ties to historic events. Proof coins, known for their mirror-like finish, are particularly coveted. Bicentennial editions or coins with historically significant mint years often carry added appeal.
Million-Dollar Quarters: Notable Examples
Here are four standout S-mint quarters that have sold for astounding prices:
1. 1932-S Washington Quarter

2. 1916-S Standing Liberty Quarter
Only 52,000 were minted, making it one of the rarest S-mint quarters. High-grade examples have fetched as much as $2.4 million.
3. 1927-S Standing Liberty Quarter
With 1.6 million minted, it’s not the rarest, but its value spikes with condition. Pristine versions can sell for $100,000 or more.
4. 1896-S Barber Quarter
One of the most elusive Barber quarters, the 1896-S is extremely rare in good condition. Collectors have paid $100,000+ for well-preserved pieces.
How to Identify Rare S-Mint Quarters
Think you might have struck gold (or silver)? Here’s how to tell if your coin is something special:
- Find the Mintmark
Look for a small “S” on the reverse side, usually near the eagle’s talons or along the rim. - Check the Year & Mintage Numbers
Some years are far rarer than others. Compare yours to published mintage records. - Evaluate the Condition
Examine for scratches, wear, or tarnishing. Higher-grade coins are significantly more valuable. - Seek Expert Evaluation
A certified coin dealer or numismatist can provide a professional appraisal and grade.
Tips for Collecting S-Mint Quarters
- Study Before You Buy: Know what you’re looking for. Research years, types, and grading scales.
- Condition is Everything: Whenever possible, invest in coins with minimal wear.
- Buy from Trusted Sources: Work with reputable dealers and insist on authenticated coins.
- Store Coins Properly: Use protective cases or capsules to prevent wear, moisture, and damage.
