Frequently Asked Questions
How do I know if my series 2013 $1 has the duplicated serial number error?
To determine if your Series 2013 $1 bill has the duplicated serial number error, you need to check three things: the series, the Federal Reserve Seal, and the serial number itself.
1. Check the Series
Look at the front of the bill, to the right of George Washington's portrait. It must be a Series 2013 note.
2. Check the Federal Reserve Seal
The bill must have a "B" federal reserve seal. This seal is a letter inside a circle, located on the left side of the bill, below the words "FEDERAL RESERVE NOTE."
3. Check the Serial Number
The serial number must end with a star (*) and fall within one of two specific ranges:
B00000001* to B00250000*
B03200001* to B09600000*
If your dollar bill meets all three of these criteria, it is one of the notes from the duplicated print run. Finding one of these bills is a rare and exciting discovery, and you may consider registering it with one of the online communities dedicated to helping people find the matching pair. Images and further detail can be found in the Duplicate Serial Number Guide
What is a 'star note'?
A "star note" is a replacement banknote issued by the Bureau of Engraving and Printing (BEP) to replace a bill that was damaged or misprinted during the production process.
What serial number ranges apply to the duplicated serial number production error?
The serial number ranges that apply to the duplicated 2013B star note production error are: B00000001* – B00250000* and B03200001* – B09600000*. To be a part of this error, a bill must have one of these serial numbers, be a Series 2013 note, and have a "B" federal reserve seal. The duplicates were created because the Bureau of Engraving and Printing (BEP) facilities in Fort Worth, Texas, and Washington, D.C., both printed notes with these same serial number ranges.
Why are 2013B duplicate star notes valuable?
The value of these notes comes from an extremely rare printing error. Two different printing facilities—one in Fort Worth, Texas, and the other in Washington, D.C.—unknowingly produced duplicate batches of star notes for the 2013 series. This error resulted in two bills with the exact same serial number, which should never happen. The existence of these pairs is what makes them highly collectible and valuable to paper currency collectors.
Will I be contacted when a bill matching the serial number of my bill is submitted to this site?
Yes! Usually within 24 hours. Once you registered your bill, you don't need to do anything further but wait for email notification when and if a match is found for your bill. This is the main purpose of this site! Be sure to check you spam folder (or junk mail folder) as well. Any message coming from this website will have 'Project 2013B' somewhere in the subject line.
Why should I submit my serial numbers to Project 2013B?
Submitting your bill to Project 2013B gives you the best chance of finding its matching note. This project has the largest database of these specific bills on the internet, with over 80,000 unique serial numbers as of August 2025. This project is the most prominent resource for this effort and has been featured in news outlets such as Coin World, Fox News, and The New York Post. By registering your bill, you're joining a community-driven effort that has already successfully united over 190 matched pairs. Without your submission, no one will know that your bill exists, and your chances of finding its valuable twin are virtually zero. A friend of mine search over 4,000 dollar bills he withdrew from his local bank, and his search yielded only ONE 2013B star note. Now think about what are the odds of him searching another 4,000 notes, finding another 2013B star note, and that star note having the same serial number as the previous star note he found? Although all dollar bills are printed in only 2 facilities, those dollar bills are distributed to all the banks throughout the US. You match could easily be on the other side of the country, or even outside of the US itself.
I have hundreds to 2013B star notes, but I don't want to register them one at a time!
There is a process for bulk submissions if you have 20 or more notes at bulk.2013b.com
What is the difference between submitting and registering my bill in this project?
Nothing. I use the words interchangeably. It simply describes getting your serial number(s) into the database (also known as 'The List').
I have a 2013 bill that is in range but it doesn't end with a star. Does this count as anything?
NO.
Can I sell a single note?
Yes, you can sell a single 2013B star note, but it's important to understand the significant difference in value between a single note and a matched pair.
A single, unmatched note from this group is still valuable to collectors. For example, in January 2025, individual notes sold for an average of $30 on eBay. These notes are often bought by collectors hoping to find the matching bill later on.
The true value of these notes is unlocked only when they are sold as a matched pair. When both bills with the same serial number are sold together, the price can increase dramatically. Matched pairs have sold at auction for anywhere from $500 to $25,000, with the price depending on the condition of the bills.
Selling a single note is a good option, but be aware that you're only capturing a fraction of its total potential value.
What if I submitted before but had no contact info?
We have removed older submissions from our database, particularly those from the Zegers-Winograd project, if they were missing valid contact information. If you were one of these users, you will need to resubmit your information to be included in our active database.
Please note: Any new submission without a valid email address will be automatically rejected.
We highly recommend providing a phone number that can receive text messages; however, a valid email address is the minimum required to be included.
Where can I sell or consign my 2013B duplicate note?
You can sell or consign through top auction houses, eBay, and Project 2013B's Marketplace.
Does a matching bill exist for each 2013 star note?
Yes, a matching bill for each 2013B star note from the specific duplicated serial number ranges does exist. This is the core of the error that makes these bills so collectible.
The error occurred because two different Bureau of Engraving and Printing (BEP) facilities—one in Washington, D.C., and one in Fort Worth, Texas—printed the same batch of replacement notes (star notes) with the same serial numbers.
While a matching bill was printed for every note in the affected serial number ranges, finding its twin is an enormous challenge. Many of these bills have been lost, destroyed, stored in collections, or are still in circulation, which is why matched pairs are so rare and valuable. This "treasure hunt" for the matching note is what drives the high prices for a complete pair.
I submitted my serial number but I didn't get any kind of confirmation, or see it anywhere on the website!
First check the status of your submission here: check.2013b.com
The status of submissions go back 3 weeks. The page also lists the most common reasons why a submission may of been rejected. If you submitted your serial number over a month ago, AND you think it was a valid number, then you will need to request a report of all of the serial numbers in the database that are linked to your email address: report.2013b.com
Please allow 24-48 hours to receive your report. If your serial number is not in the emailed report, then your serial number was probably not submitted, or rejected, or was submitted under a different email address. For future submissions, always use the same email address to keep your records organized.
I entered a bill on the submission form, but when I click, on the purple submit button, it stays on the same page. Why?
Chances are you entered an invalid email address, or one of the pieces of information you entered are wrong. There should be some red warning text on the form telling you what entry was invalid. Please refer to the graphics in the submission form. Is your bill really a $1 bill? Is it series 2013? Does it really have a 'B' seal? Does the serial number really start with a B and end with a star? Feel free to refer to (and share) the following infographic: https://project2013b.blogspot.com/2024/12/ultimate-guide-identifying-rare-2013.html
I checked the check.2013b.com link and my bill was rejected! WHY?
Scroll down the page that has the submission status table and there will be a list of 8 different reasons why a serial number was rejected.
I made a typo in the bill information I submitted! What should I do?

How long do the serial numbers remain on the list?
Your serial number submission will remain on the list permanently.
Even if you sell, spend, or lose your bill, the serial number stays in the database as a permanent record that the note exists. This is important because Series 2013B notes are becoming increasingly rare in circulation.
The Federal Reserve regularly destroys old, worn-out currency. This, combined with bills lost to fire, natural disasters, or other reasons, means that fewer of these notes are available every day. The serial numbers in the database serve as a vital record, helping collectors track and eventually find matching pairs.
Years ago I submitted a serial number and got an email confirmation. Why doesn't it do that anymore?
A lot of email providers, even gmail, have limits to how many emails you can send per day, and even per hour. The online submission status page handles this now and is available 24/7, with the added feature of telling you why your bill might of been rejected. Check this link: check.2013b.com
Why are there ads on this site?
The ads on this website help to cover the significant costs associated with running and maintaining this project.
This is a free service that helps people find their matching notes. The hours spent on maintenance, website updates, and contacting users are extensive. While donations are accepted, they do not come close to covering the total costs of operating this project. As of September 2025, this project has successfully helped co-owners sell matched pairs for a combined total of over $195,000, all thanks to this free service.
Why am I being asked for my credit card?
Project 2013B will never ask you for a credit card. You have clicked on an advertisement.
What is the cryptic looking member/Owner ID?
The cryptic ID, like Vi3P for example, is generated from your email address. It is the project's way to mention you specificially without giving away your real name.
I do not know what my Owner ID is.
In the grand scheme of things it does not matter what your Owner ID is as you are mainly identified by the project (behind the scenes) by your email address. If a match is found for your bill, you will be contacted through the email address you entered at the time of submission. If you REALLY want to know your owner ID, you can request a report of all of the serial numbers that you currently have in the Project 2013B database: report.2013b.com
NOTE: if you use a different email address each time you submit a serial number, you will be assigned a different Owner ID for that specific serial number. It does not matter if you have 1 consistent Owner ID, or 17 of them, as long as the email addresses are ones that you check for messages from this website.

I submitted my serial numbers with my email address, but where can I add my phone number?
You can submit your phone number (to be contacted by text) at change.2013b.com
What is a confirmed match?
A "confirmed match" means that a complete, duplicated pair of 2013B star notes has been officially verified by Project 2013B.
When two identical serial numbers are submitted to the database, a project administrator contacts both owners. Each owner is asked to send a photo of their bill. Once the photos are verified and the authenticity of both notes (one from the Washington, D.C. print and one from the Fort Worth print) is confirmed, the match is official.
At this point, the email addresses of the two owners are shared with each other. They can then decide how to proceed, whether it's to sell the matched pair together, or for one owner to buy the other's bill.
How can I check to see if my bill has a match?
Once your serial number is in the database, there's no need to check on its status. The list is updated daily, and the system automatically scans for new matching pairs with each update. When a match is found, both bill owners will be contacted by the project within 24 hours. Given the high volume of daily submissions (from 30 to over 200), it's crucial that you check your spam or junk folder, as the notification email may end up there. For extra peace of mind, you can add your phone number at change.2013b.com to receive a text message alert.
Can I have a copy of your list?
No. The reasons can be read about here: Restricted
I was contacted by Project 2013B that I have a bill that is part of a matching pair and responded, but the owner of the other bill has not responded at all for months/years. What should I do?
Once you've submitted your note, the process requires patience. For the price of just one dollar, you essentially have a lottery ticket for a matched pair that could be worth hundreds or thousands of dollars. Keep in mind that finding a match and connecting with the other owner can take time. There is also a chance the other bill has been spent, destroyed, or lost, meaning a match may never be found. While waiting, you may even be able to sell your single note for a premium to a collector hoping to find the matching pair themselves. Finding a match is a numbers game, and while some people are lucky, many are not. Every day, the Federal Reserve removes old, damaged currency from circulation and destroys it. This means that with each passing day, there are fewer and fewer of these valuable notes left in existence.

With the number of confirmed matches this project has produced, will the value plummet over time?
Everyday, worn-out and damaged bills get removed from circulation for destruction and replaced by new bills. As time goes by, finding a duplicate serial number pair should become harder and rarer. Based on data from the Federal Reserve, the average lifespan of a dollar bill in circulation is about 6.6 years. Given this, it's estimated that only around 15-20% of Series 2013 $1 bills are still in circulation today. The Federal Reserve estimates that around 7-10% of currency is removed from circulation each year due to wear and tear, damage, or being taken out of circulation for other reasons. This percentage applies broadly to all denominations, including Series 2013 $1 bills.
Will my name or email address ever be shown or shared on this website or the database?
No. Privacy is priority #1. Some people on the list are serious paper money collectors and coin collectors. No one wants to advertise that their home might have valuables in it. Also, no one wants SPAM, nor scams. Each member of the project is only referred to by a crptic 3-5 character code. E.g. qdiHP

I saw a website with the same name as your project other than a version number on the end. What is it?
It is a copy-cat site, where the individual could not even come up with an original name. I refer to him as "Sly".
Sly, an unethical individual, created a copycat version of my website. Although he is free to create his own site and list, it was dishonorable to copy my project name and simply add "2.0." This small change has already caused confusion among users. Some have asked if it is a new version, while others have asked if THIS site is still active. THIS SITE is VERY MUCH ACTIVE.
Additionally, Sly copied an old list of 47,066 serial numbers from Project 2013B without permission. This list did not include contact information for the banknote owners, nor their identities. Nevertheless, Sly falsely inflates his total serial numbers to over 60,000, misleading users about the true scope and integrity of his database.
If you are ever in doubt as to which site is the Original (and BEST), simply go to 2013b.com
I type 2013b.com, but the address in the browser changes
The address 2013b.com is an easy to remember address that simply redirects to this specific website. It is easier to remember (and in my case promote) than the address of https://project2013b.blogspot.com/
How can I help?
You can help Project 2013B by spreading the word. Share information about the project with friends and on social media platforms like X, Reddit and Facebook. The more people who know about the project, the greater the chance of finding a match for your bill. You can also visit the website regularly, as increased traffic helps the site's visibility on Google. Feel free to use and share the promotional images and materials found at promote.2013b.com to help get the word out.
