Collectors will pay a premium for unique coins or rare bank notes. So, if you’ve got any $1 dollar bills lying around, you may want to examine them closely before spending them as they could be worth thousands.
Ordinarily, dollar bills each have their own individual serial numbers. However, in 2014, the Bureau of Engraving and Printing made a rare printing error that resulted in millions of $1 bills with duplicate serial numbers entering into circulation, according to PMG, the world’s largest third-party paper money grading service.
Although these special pairs of $1 bills with matching serial numbers were initially printed in Washington, D.C., and Forth Worth, Texas, they could be anywhere in the world after a little more than 10 years in circulation.
It’s important to note that the misprint doesn’t make these $1 bills unusable, and they’re probably not worth more than a dollar on their own. However, if you manage to find a matching pair, you could earn thousands from collectors.
A pair of $1 bills with duplicated serial numbers sold for $2,340 at an auction held by Stack’s Bowers in March. Another pair sold for $7,200 at a Stack’s Bowers auction in 2021.
