Collecting rare currency can be both an exciting and profitable hobby. One type of currency that stands out among collectors is the “solid serial number” bill, where every digit in the serial number is identical,
like 88888888 or 55555555. These bills are rare and highly valuable. In this article, we’ll explore what solid serial number bills are, how to identify them, and which denominations are worth the most.
What Are Solid Serial Number Bills?
Solid serial number bills have serial numbers where all eight digits are the same, such as 11111111 or 99999999.
These bills are rare, making them valuable to collectors for both their uniqueness and aesthetic appeal. Due to the limited number of these bills in circulation, their value increases over time.
How to Identify Solid Serial Number Bills
Identifying a solid serial number bill is easy. Just follow these steps:
- Check the serial number: Look at the upper right and lower left corners of your bill to see if the serial number has the same digit repeated across all eight spaces.
- Condition matters: Bills that are uncirculated or in mint condition are worth more, so try to preserve their quality.
- Series year: Older series are more valuable, so be sure to check the year printed on the bill.
