Could your Rare $5 Note be Worth $4.5 Million:The idea that an ordinary piece of paper—one that slips through wallets, cash registers, and coat pockets unnoticed—could secretly be worth a lot of money is fascinating. That’s what happened with a rare five-dollar bill bearing a radar serial number, specifically 31000, that has attracted a lot of collectors. In fact, some currency experts say the note could be worth as much as $4.5 million.

Yes, you read that right. A five-dollar bill. Worth millions.
So, how can you tell if your ordinary five-dollar bill is one of these exceptional rarities? The answer lies in a unique serial number, an immaculate condition, and an incredibly rare printing pattern that few people in the world have ever seen.
Let’s take a closer look—and help you figure out if you’re unknowingly sitting on a multimillion-dollar treasure.
What is a radar serial number?
First, let’s understand the term. A radar serial number is one that looks the same on the front and back—like a mirror image. Think of it like a numerical palindrome.
Here are some simple examples:
- 1234321
- 5441445
- 3100013
Radar notes are considered valuable by collectors because of their symmetry and rarity. Most notes have randomly assigned serial numbers printed on them. A radar number, especially one with a low number or a repeated pattern, is already rare. Combine that with excellent condition and a unique pattern, and you’ve got the recipe for something really valuable.
The “31000” serial number is particularly rare. Although it’s only five digits long, it’s part of a larger 8-digit serial stamped on the bill—which appears as 00031000—making it a perfect radar. The low number and mirror-reflection quality make it different from common radar notes.
The five-dollar note that stunned the collecting world
The reason this particular radar note is so famous is that a five-dollar note from the 2009 series, with serial number 00031000, surfaced in 2024 and was certified as a radar note in perfect condition. It was graded Gem Uncirculated 68 EPQ by PMG (Paper Money Guarantee), one of the highest grades possible.
When it was quietly offered at a private auction, bidding was fierce. Collectors knew what they were looking at: a unique note passed down from generation to generation.
The final bid? A staggering $4.5 million.
Yes — for a five-dollar note.
It shattered previous records and instantly became one of the most expensive small denomination notes ever sold.
Why so valuable?
Several factors play into its historic value:
- Perfect Radar Serial Number (00031000) – Not only is it a Radar, but it also has zeros imprinted on it, making it rare and highly sought after.
- Low Denominations – High-value flawed or rare notes in small denominations are especially attractive, as they often slip into circulation unnoticed.
- Perfect Condition – Grade 68 EPQ, which means it’s crisp, uncirculated and exceptional in every way.
- Historical and Collector Demand – As demand for rare U.S. currency continues to grow, prices for excellent currencies are skyrocketing.
How to Check Your $5 Notes
If you’re now eager to check every $5 note you own (and you should!), here’s how:
Step 1: Check the serial number
Look for the radar pattern: the number should be the same on the front and back.
Look for small numbers with symmetry or unique repeated digits (e.g. 00031000, 1234321, 7880887).
Step 2: Check the series year
Most radar notes of interest to collectors come from recent series: 2006, 2009, 2013, 2017A.
Step 3: Check the condition
Notes without folds, wear and tear and with sharp edges are worth a lot more.
Even a radar note in poor condition might not fetch much money – but in good condition? This could be a game changer.
Step 4: Verify with collectors
If you think you’ve found something, consult forums or collectors.
Get it authenticated with a PMG or PCGS banknote.
What to do if you find one
- Don’t spend it – it’s not just five dollars anymore.
- Handle it with care – use gloves or a currency sleeve to avoid scuffing or damage.
- Get it authenticated – a grading service can verify and evaluate it.
- Consult an auction house – reputable auction houses like Heritage Auctions or Stack’s Bowers can help you sell it safely.
