Have you ever held a penny and wondered if it could be worth a fortune? Hidden among ordinary coins lies one of modern numismatics’ most elusive treasures—the 1999-S “Close AM” Proof Lincoln Cent. With only a handful known to exist, this unassuming penny has sold for over $1.2 million at auction. Could one be hiding in your collection?
The Million-Dollar Mystery: What Makes This Penny So Valuable?
In 1999, the U.S. Mint accidentally struck a small number of proof pennies using a 1998 proof die, creating a rare and highly sought-after variety. The key identifier? The letters “A” and “M” in “AMERICA” nearly touch, unlike the widely spaced “AM” on standard 1999 pennies.
Why Collectors Are Willing to Pay Millions
- Extreme Rarity: Only five confirmed specimens exist, all held in private collections or museums.
- Historical Significance: A minting error that was never supposed to happen.
- Elite Demand: Top collectors and institutions compete fiercely when one appears at auction.
How to Spot the 1999-S “Close AM” Proof Penny
Before you start digging through your spare change, here’s what to look for:
The “Close AM” Feature
- Examine the reverse side of the coin.
- The “A” and “M” in “AMERICA” should almost touch (compare to a normal 1999 penny, where they’re clearly separated).
Proof Quality
- Must be a San Francisco (S) Mint proof coin with a mirror-like finish.
- Look for sharp details and no signs of wear.
Red Flags & Common Mistakes
- Normal 1999 pennies (even S-mint proofs) are not valuable unless they have the “Close AM” error.
- Beware of altered coins—experts can spot fakes instantly.
What to Do If You Think You’ve Found One
- Handle with Care
- Hold the coin by its edges to avoid fingerprints.
- Never clean or polish it—this destroys its value.
- Magnify & Compare
- Use a 30x-40x loupe to check the “AM” spacing.
- Compare it to verified images of the “Close AM” variety.
- Get It Certified
- Submit it to PCGS or NGC for professional authentication.
- High-grade examples (PR-69 or PR-70) can fetch $250,000 to $1.2 million.
The Thrilling Market for Ultra-Rare Errors
The last known sale of a 1999-S “Close AM” proof penny set a record at $1.2 million, and prices are still climbing. Why?
- Museums and investors are competing to own a piece of numismatic history.
- Registry set collectors (those who aim for the most complete collections) will pay top dollar to complete their sets.
- Modern errors are outperforming classic coins in auction results.
A Word of Caution: Don’t Get Scammed
While the dream of finding a million-dollar penny is exciting, beware of:
- Fake listings online claiming to sell this rare coin.
- “Too good to be true” offers—always verify with a grading service.
- Altered coins that mimic the “Close AM” look but aren’t genuine.

Submit high-resolution photos to a trusted coin authentication service.
