While it may seem like $1 and $2 bills aren’t worth much on the surface, you should hold on to them just in case, because certain denominations may be worth more than you think.
Several versions of these bills are worth thousands of dollars and some currency collectors are willing to pay top dollar for them.
So, if you have a $1 or $2 bill stashed in your wallet or under the sofa, here’s what you should look for to determine the value.
How to find $1 bills worth thousands of dollars
Some $1 bills printed in 2014 and 2016 are highlighted by a mistake from the US Bureau of Engraving and Printing that could make the denominations worth $150,000 by collectors, per Wealthynickel.com.
There are approximately 6.4 million $1 bills printed with this error in 2014 and 2016, the Bureau of Engraving and Printing noted.

If you believe you’re holding one of these rare $1 bills, Wealthynickel shares three things to look for to find the misprinted bills possibly worth a ton of cash:
- The series date located near the photograph of George Washington must read "Series 2013"
- The bill must have a "B" Federal Reserve seal above the serial number
- The serial number must end with a star (*) and fall between B00000001* – B00250000* or B03200001*-B09600000*
One thing to remember is the value of this specific misprint is pairing it to the other bill with a matching serial number. According to Wealthynickel.com, there have been 37 complete pairs identified so far.
Experts estimate that matching pairs of bills would sell for between $20,000 and $150,000, depending on the condition and serial number.
