What Is a Star Note?
A star note is a replacement currency note printed by the Bureau of Engraving and Printing (BEP). When a misprinted or damaged note is removed from a batch, it is replaced by a new one with a star symbol at the end of the serial number — hence the name.
- Star notes are used to maintain the correct count of notes in circulation.
- They are relatively common, but some runs are very limited, making them more valuable.
What Is a Duplicate Star Note?
A duplicate star note refers to two different star notes that share the exact same serial number, including the prefix, number, and star.
This happens under very rare circumstances — often when a printing error or system overlap results in the accidental duplication of serial numbers.
There are two known types of duplicates:
- Same serial number across different Federal Reserve districts
- Same serial number within the same district (much rarer)
💡 Keyword Alert: A duplicate serial number on U.S. currency is extremely rare and can increase collector interest significantly.
How Do Duplicate Star Notes Happen?
The BEP prints notes for multiple Federal Reserve Banks. Each bank uses a unique letter prefix and has its own serial number series. However, due to massive production volumes and complex printing schedules, there are rare instances where duplicate serial numbers are printed — especially among replacement star notes.
This typically occurs when:
- Two districts use overlapping star note serial ranges
- A manual or system error fails to detect a duplicate
- Older production systems create an oversight
Important: These are unintentional errors, and the BEP does not recall such notes unless discovered immediately.
How Rare Are Duplicate Star Notes?
Extremely rare. While star notes themselves are not unusual, duplicate star notes are considered collectible oddities. Only a small number of confirmed cases exist, and they are often documented by numismatists or posted in collector forums.
The odds of finding one are estimated to be less than 1 in several million — especially if they’re from the same district.
Bold Keyword: If you find a duplicate star note with matching serial numbers, it may be worth a premium due to its rarity and error status.
How to Confirm a Duplicate Star Note
To verify whether you have a duplicate star note, follow these steps:
- Check Serial Number Format
- Make sure both notes have the exact prefix, numbers, and star at the end.
- Compare Federal Reserve Bank Indicators
- Look for different district letters or seal identifiers.
- Authenticate Both Notes
- Confirm they are not altered or counterfeit.
- Consult Collectors or Forums
- Share your find on trusted paper money forums or consult a certified appraiser.
🧠 Tip: High-resolution scans and detailed photos help with authentication.
What Is a Duplicate Star Note Worth?
The value of a duplicate star note depends on multiple factors:
| Factor | Impact on Value |
|---|---|
| Condition (Grade) | Crisp, uncirculated notes fetch more |
| Series Year | Older notes can be rarer |
| Matching Pair | Value skyrockets if you own both notes |
| Districts Involved | Same-district duplicates are more valuable |
| Verified Rarity | Published or recognized finds have collector appeal |
⚡ Estimated Value Ranges:
- Single duplicate star note (unverified match): $10–$50 (if condition is good)
- Verified pair of duplicate star notes: $500–$2,000+ depending on condition and demand
- Historic or rare series match: $5,000 or more (very rare)
If you have both notes in the pair, your find could be extremely valuable to collectors looking for unique printing errors.
How to Sell a Duplicate Star Note

What If I Only Have One of the Pair?

Some collectors may even offer to buy the note in hopes of completing the pair.
Conclusion
