Ever pulled out a $5 bill and thought nothing of it? In July 2025, one collector did—and later learned it was worth $66,000.
That’s right: a seemingly ordinary note turned out to have a rare “super radar” serial number and perfect condition, making it a numismatic goldmine.
What’s a “Super Radar” Serial Number?
Every U.S. bill has a unique serial number assigned by the Bureau of Engraving and Printing, but some patterns stand out:
| Pattern Type | Description |
|---|---|
| Radar / Palindrome | Reads the same backward and forward |
| Super Radar | Palindrome with extra matching digits at ends |
| Low Serial | Starts with many zeros (e.g. 00000055) |
| Repeater | Repeating digits (e.g. 45454545) |
| Ladder | Sequential ascending or descending (e.g. 12345678) |
| Solid | All digits the same (e.g. 77777777) |
These fancy serial numbers are rare—and when they land on a crisp, uncirculated note, collectors pay top dollar.
The $66,000 $5 Bill — What Made It Special?
- Serial Number: Radar-style “super radar” (e.g., 40000004 pattern)
- Grade: Gem uncirculated—no folds, blemishes, or wear
- Sale Price: $66,000 at U.S. auction in July 2025
The combination of a unique palindrome, perfect condition, and newer printing year (2024–2025) made it irresistible to collectors.
Why Serial Number Patterns Matter
Collectors look for these high-value traits:
- Palindrome / Radar: Serial reads identical in both directions
- Super Radar: Extra symmetry at the start and end digits
- Low numbers: e.g., 00000055 is ultra-rare
- Condition: Gem uncirculated notes fetch the highest premiums
Even modern bills—not just antique notes—can carry serious collector value due to these traits.
Common Fancy Serial Values
According to a market guide:
- $5 six-of-a-kind green serials: $10–$15, red: $15–$20+
- Double-digit low serials (00000055 style): $60–$90+
- Super radar or ladder: Market prices escalate significantly
But note: each auction is unique, and exact sale prices can vary.
How to Check Your Wallet for a Windfall
- Examine Serial Numbers: Look for palindromes, repeated digits, low numbers
- Condition Counts: Crisp, uncirculated notes are worth far more
- Verify Serial Matches: Front and back should be identical
- Get Expert Opinion: Submit to grading services like PMG or PCGS
- Tap Auction Houses: If authenticated, list it—some have dedicated currency auctions
A Reddit user emphasized:
“The ‘bill serial number’ collector market is very small and totally fickle.
That means values may vary—but a rare find can be life-changing.
Why These Sales Still Happen
- Millions of bills print daily—rare serials slip into circulation
- Collectors hunt actively, so even recent vintage notes can fetch big
- High-grade notes often come from untouched ATM withdrawals or collections
Your next trip to the café might include a collector’s dream in your change.
What seems like a just another $5 bill may actually be worth tens of thousands of dollars—if its serial number is rare and it’s in gem condition.
The $66K sale in July 2025 proves modern payroll prints can still surprise. So next time you handle a crisp $5, inspect the serial, keep it safe, and consider grading before spending.
