A 2013 $20 bill might be worth more than its face value—if you know what to look for. Across the U.S., collectors are buzzing over a rare printing error that slipped through the cracks and made its way into general circulation. This anomaly, known as a serial number mismatch, has turned a few ordinary bills into highly sought-after collectibles, and some may still be hiding in wallets and cash registers today.
What Is a Serial Number Mismatch?
Every U.S. dollar bill is printed with two identical serial numbers—one on the left and one on the right side of the front. These serials are supposed to match perfectly. However, due to a rare printing mistake during the production of certain 2013 $20 bills, a small number of notes were released with non-matching serial numbers—a detail most people wouldn’t even notice at first glance.
Such mismatches are extremely uncommon and are considered “error notes” in numismatic circles. These bills defy standard protocol and instantly stand out to collectors who value printing oddities. When authenticated, these bills can fetch hundreds or even thousands of dollars, depending on their condition and how drastic the error is.
How This Error Happened
According to currency experts, the error likely occurred at the Fort Worth, Texas, facility of the Bureau of Engraving and Printing, one of the two locations responsible for producing paper currency in the United States. In rare instances, sheets of bills are accidentally overprinted or misaligned, leading to mismatched serials or even mismatched seals and series years.
This printing mistake was not caught before the notes were bundled, packed, and sent to banks for distribution. As a result, the flawed bills entered everyday circulation, and a few lucky individuals unknowingly became the owners of potential collector’s items.
How to Check Your 2013 $20 Bill
To determine whether you’re holding one of these rare error notes, take a close look at both serial numbers on your 2013 $20 bill. They should be identical—but if even one digit is different, you could be looking at a valuable rarity. Here are some things to inspect:
- Compare the left and right serial numbers carefully.
- Ensure you’re looking at a 2013 series note (this is printed near the bottom right corner of President Andrew Jackson’s portrait).
- Look for unaltered and undamaged bills, as pristine condition increases value.
- Check the Federal Reserve seal—any inconsistencies here could also be a red flag for an error.
Recent Sales and Collector Interest
Collectors have already paid top dollar for authenticated 2013 $20 bills with this rare mismatch. On various online marketplaces and auction sites, such bills have sold for $500 to $2,000 depending on rarity and bill condition.
As awareness spreads, more people are checking their wallets, especially with inflation making even small windfalls feel significant. With limited error notes confirmed, demand is high—and rising.
Should You Hold or Sell?
If you discover a serial mismatch on a 2013 $20 bill, you have two options: hold it as a long-term collectible or sell it now while demand is strong. Either way, you’ll need to get it authenticated by a trusted currency grader like PMG (Paper Money Guaranty) or PCGS Currency to prove its legitimacy and determine its true value.
