Series 2013 Duplicate Serial Number Notes Pass $200K in Auctions

Since it launched, Project 2013B has verified well over 200 matched-pairs of the rare series 2013B “duplicate serial number” star notes. Impressively, many of those matched pairs have moved into the collector market and been sold or auctioned. Combined, just the portion of matched pairs that have gone through auctions have now generated over US $200,000 in hammer prices — a milestone that underscores how these pieces of currency-error history have become vibrant collector items. 

 What’s more, the project continues to maintain a detailed, publicly accessible record of auction history — you can explore this full list of sales on the project’s own site at auction-history.2013b.com . This snapshot not only reflects the growing demand for these matched pairs, but also provides valuable transparency around what the marketplace is willing to pay for them. 

 While the momentum behind these sales has been remarkable, it’s also clear that pricing for matched pairs can be highly volatile, even among notes of the same grade. Because the market is still relatively young and many collectors are only beginning to learn about the 2013B duplication error, realized prices can swing significantly from one auction to the next. Over time, however, as more sales data accumulates and the error becomes more widely recognized within the paper-money community, these values are expected to stabilize. The continually expanding auction record—documented at auction-history.2013b.com—will play an important role in helping collectors and dealers better understand fair market ranges for these unique matched pairs.
