Are you M.I.A?

Do you have a match but are not aware of it?


Project 2013B might already be looking for you!

Be sure to check the latest blog entry to see if any of your serial numbers are there. These are serial numbers of matching pairs that were discovered in the database, but are NOT verified since we have yet to hear back from one (or both) banknote owners!


New Submissions:
Anyone who submits more serial numbers in the future, but uses a different email than in the past, your member ID will be different since the ID is automatically generated using your email address as an input which is then encrypted.

2013B Serial Number Database
Project 2013B News and Blog
Each month there is a list of missing members published in the newsletter



Special note for people who registered with the Zegers/Winograd Project or thru SilverPicker:

Close to 100% of the serial numbers that are marked as having no email address are from the previous Zegers/Winograd list or submissions from the SilverPicker site. Due to 'privacy concerns' the list owner did not pass on the email addresses to Project 2013B. Since the start of Project 2013B, many have come forward to submit their contact information, but many have not (or are simply not aware). 

When a matching pair is discovered in the database, but one of the bill owners is from the Zegers/Winograd list and missing an email address, the previous list owner was cooperative in contacting the bill owner if he had the contact information. This is NO LONGER THE CASE. 

Anyone who was on the original  Zeger-Winograd list who did not submit their email address to Project 2013B has been purged from the list, and will need to re-submit their serial numbers.  Those members had over 2 years to update their contact information, and it has become a real waste of time and effort to detect a newly matched pair, only to disappoint the other party that there is "no email on file" for the person who has the matching bill.
