The 2013 $1 “B” star notes* have captured the attention of collectors due to a rare printing anomaly: duplicate serial numbers. In this unusual occurrence, the Bureau of Engraving and Printing mistakenly printed 6.65 million $1 Federal Reserve Bank of New York (“B”) star notes twice within specific serial ranges: B 00000001 – B 00250000** and B 03200001 – B 09600000**.
This error has created a unique collecting challenge—finding pairs of notes with identical serial numbers, often called “Twins.”
The Value of a Twin Pair
Because these Twin pairs are a printing error and extremely rare, they are highly sought after by collectors and investors alike. Their scarcity is a major factor driving up value.
Limited Finds
As of early 2022, only about a dozen Twin pairs have been located and reunited, making them exceptionally rare.
Auction History
One Twin pair appeared in two public auctions: first selling for $7,200 in August 2021 at Stacks & Bowers, and later for $9,300 in March 2022 on eBay.
Value Potential
While these two sales don’t establish a definitive market value, a Twin pair in good condition is expected to fetch several thousand dollars.
This rare printing error has turned what would otherwise be ordinary $1 bills into highly collectible treasures. The hunt for these elusive Twins continues to excite collectors, adding an extra layer of thrill to star note collecting.
