Think all the valuable pennies have already been found? Think again! Until recently, collectors believed that every 1990 No-S Proof Penny was accounted for—but that theory just got shattered. Three more have been discovered, proving that these ultra-rare coins are still out there.
What Makes This Penny So Valuable?
The 1990 San Francisco Proof Penny is supposed to have an “S” mint mark below the date. However, a rare error resulted in a small batch being struck without the “S” mint mark—a mistake that now makes these coins worth over $3,500 on average!
How to Identify a 1990 No-S Proof Penny
- Look at the finish – A proof penny has a mirror-like surface, while a regular penny looks dull.
- Check for the mint mark – All 1990 proof cents should have an “S” below the date.
- No “S”? Jackpot! – If your proof penny is missing the “S,” you may have struck gold!
