Does This Mark on a $20 Bill Make It Valuable? What Collectors Should Know
Finding an unusual symbol on a banknote can make anyone wonder whether they have discovered something rare. A viral image circulating online shows a U.S. $20 bill with a small handwritten-looking mark circled near the left side of the reverse, accompanied by the claim that people who own a bill with this feature are especially lucky.
But does this mark actually make the banknote valuable?
An unusual mark alone does not make a $20 bill rare or valuable to collectors. Its significance depends on how the mark was created, whether it is part of the original printing, and whether the banknote has other collectible features.
1. What Is the Mark on the Bill?
The circled symbol appears to be a small dark mark on the printed surface of the banknote. From the photograph alone, it is not possible to determine whether it is handwriting, an accidental ink mark, damage, or a printing-related feature.
Marks added after a bill leaves the printing facility are generally considered alterations or damage rather than valuable printing errors.
To identify the mark accurately, collectors would need a clearer close-up and information about the note’s series, condition, and other identifying details.
2. Can a Printing Error Make a $20 Bill Valuable?
Yes. Certain genuine U.S. currency printing errors can attract collector interest. Examples may include:
Misaligned printing that affects the design.
Missing or incomplete printing caused by a production error.
Incorrectly positioned serial numbers or other verified printing anomalies.
Certain unusual errors confirmed to have occurred during production.
However, not every irregularity is a genuine printing error. Ink stains, pen marks, folds, scratches, and damage that occur during circulation generally do not qualify as valuable minting or printing errors.
3. What About Rare Serial Numbers?
Sometimes a banknote’s serial number is more important to collectors than a small mark on its design.
Examples of potentially collectible serial numbers include:
Solid numbers: All digits are identical, such as 77777777.
Repeating patterns: Numbers such as 12121212.
Low serial numbers: Notes with unusually low serial numbers.
Radar numbers: Numbers that read the same forward and backward, such as 12344321.
Ladder numbers: Sequential digits, such as 12345678.
The value of a particular note depends on the serial number, condition, demand, and other factors. A special serial number does not guarantee a high selling price.
4. How Can You Check Whether Your $20 Bill Is Valuable?
If you have a note with an unusual mark, take these steps before assuming it is rare:
Examine both sides under good lighting.
Identify the series year and serial number.
Check whether the mark appears to be part of the original printing or was added later.
Compare the note with reliable references for recognized U.S. currency errors.
Ask a reputable banknote dealer or currency authentication specialist for an assessment if the feature appears unusual.
Avoid cleaning, erasing, or altering the banknote, as this could reduce its collectible value.
5. Should You Keep a $20 Bill With This Mark?
You can certainly keep it as a curiosity, but there is no reliable evidence from the image alone that the mark makes the note rare or exceptionally valuable.
A collector would need to examine the banknote’s overall condition, printing characteristics, serial number, and provenance before making a meaningful valuation.
Final Thoughts
An unusual symbol on a $20 bill may look intriguing, but it does not automatically make the note a collector’s treasure. Genuine printing errors and unusual serial numbers can sometimes increase a banknote’s value, while ordinary marks added during circulation generally do not.
Before spending money on an appraisal or assuming you have found a valuable bill, verify the feature carefully. The real value lies in the banknote’s documented characteristics—not simply in a mark highlighted by a viral social media post.
