We are SLOWLY getting a better feel on the value of these matched pairs. When I first learned of the 2013B printing error a few years back, there were some heady prediction as high as $150,000! Well, maybe if both notes were graded 70 EPQ (exceptional paper quality), and the serial number was 00000001.
As these auctions happen, I will update the following table. This table has been added to the online database and can be found at this link: Auction History
TIP: If you are new to currency collecting and have a bill in 'like brand new' condition, DO NOT FOLD THE BILL! As soon as a bill shows evidence of being folded the highest grade it will get is a 58.
Here is the ebay listing once the auction ended:
