Welcome Treasure Hunter

This site was created to revive a failed manual attempt to offer a free matching service for 2013B Star Note Duplicate $1 bills. That site was: "Project 2013B", https://project2013b.blogspot.com/2021/10/welcome.html.


Duplicate Dollars is an attempt to resurrect that idea. Not with manual labor and time, but instead putting compute and automation behind the effort.

No human is needed to curate and contact matches. This is done in real-time. We are continuing the aspect of privacy, by keeping match owners contact information private. When a match is located, email notifications are sent, your dashboard is updated and a private MatchChat chatroom on the site is created. This allows the dealing to go forward between the parties. In the event you want peace of mind, we offer a service to broker the deal.


Yes, we charge .99 cents per month, it's not a lot. You have lost more in the laundry. The charge helps maintain the code and keep me in an occasional beer. If 0.99 is too much for you to invest in this hunt, then you should not be hunting. In the end you get what you pay for. Good Luck!
