Let’s explore why, and how you can check if you’re sitting on a fortune.
What Makes a $5 Bill Valuable?
While most paper money is worth only its face value, there are certain features collectors crave including:
- Rare serial numbers
- Printing errors or misalignments
- Unusual patterns like repeaters, radars, and low numbers
- Condition (uncirculated bills are best)
- Unique historical significance or limited print runs
In the case of this headline-grabbing $5 bill, it’s the serial number 00031000 a rare radar pattern that caught everyone’s attention.
What Is a Radar Serial Number?
A radar serial number is a palindrome it reads the same forward and backward.
For example:
- 12344321
- 04555450
- 00031000
These serials are extremely rare, especially when they appear cleanly centered and on older notes. Collectors are particularly interested in numbers with:
- All zeros with a pattern in the middle
- Birth years (like 19901990)
- Low serial numbers (e.g., 00000001)
- Repeating patterns (e.g., 12341234)
The serial 00031000 is special because it’s not only a radar number but also a “pocket mirror” number meaning it reflects perfectly from the center outward.
