I shared it on social media, because I was so fascinated with the idea. I have since had several friends claim records that belonged to them. They simply had to verify their information, and the money came to them from the various state treasuries where it was sitting.
I check my name periodically, because the information is updated regularly. I have yet to find any records in my name in any of the states in which we've lived, but I think that's because I've always been careful to redeem all discounts and reclaim any deposits that were mine.
Not every state currently participates, but every state should have an "unclaimed property" database; if a place where you live or have lived is not linked to this site, you can search for your state's name and "unclaimed property" and it shouldn't be difficult to find.
I encourage you to check your name in any state where you have lived, and see if you might have a little surprise bonus sitting in a treasury, waiting for you. Let me know in the comments if you find anything!
