In a surprising turn of events in the world of rare currency collecting, a $10 bill with an extremely rare “ladder” serial number — 12345678 — recently sold for a staggering $96,000 at a U.S. currency auction. While it may look like an ordinary bill to the untrained eye, this note has become a hot topic among collectors and investors alike.
So why is this serial number so special? And could you be carrying one of these valuable bills in your wallet or stash without even realizing it?
What Is a Ladder Serial Number?

A ladder serial number is a sequence where the digits run in perfect ascending or descending order. For example:
- 12345678 (ascending)
- 87654321 (descending)
These serial numbers are incredibly rare because only one such note can exist per denomination and series for each configuration. Since serial numbers are randomly printed, the chances of a perfect sequential run on any bill are slim.
Why This $10 Bill Sold for $96,000
The bill in question wasn’t made of gold, nor was it from a century ago. It was a modern $10 Federal Reserve Note with a pristine ladder serial number. Here’s what made it stand out:
- Perfect condition (graded by a professional agency)
- Extremely rare serial number
- Strong demand from collectors
The bill was auctioned through a major currency auction house and drew massive interest due to its serial number alone. Experts say that even worn versions of ladder serials can sell for thousands — but this one, being in near-perfect condition, took things to another level.
How Rare Are Ladder Serial Numbers?
Out of the billions of banknotes printed by the Bureau of Engraving and Printing, ladder serials are one of the rarest types. To put it into perspective:
- There are only 90 possible combinations of 8-digit ladder serials.
- Each Federal Reserve district can issue just one per combination.
- The odds of randomly receiving a ladder bill from an ATM or cash register? Astronomically low.
Still, they’re technically in circulation, and that means there’s a chance you could find one.
What To Look for in Your Wallet
Before you spend your $10 bill, take a quick glance at the serial number in the top right and bottom left corners. You’re looking for:
- Sequential serial numbers (12345678 or similar)
- Repeater patterns (like 12121212)
- Radar serials (palindromes like 12344321)
- Low serial numbers (like 00000001)
Even if you don’t have a ladder bill, some of these patterns can still make your currency worth far more than face value.
Collector Interest Is Growing
The growing interest in rare serial number bills is being fueled by social media, online marketplaces, and live auctions. Collectors are not just looking for old or misprinted bills anymore — they’re chasing rarity through numbers, even on modern notes.
Currency dealers report that some rare serial-numbered bills are now being bought and sold like NFTs — a blend of finance, art, and collectibility.
What Should You Do If You Find One?
If you’re lucky enough to find a bill with a ladder serial number:
- Do not spend it.
- Keep it in a protective sleeve or plastic holder to avoid damage.
- Have it professionally graded by a service like PMG (Paper Money Guaranty).
- Consider listing it with a reputable auction house or dealer.
Some collectors will pay thousands for even lower-grade examples, depending on the rarity and demand.
