The $2 bills you have are Federal Reserve Notes which have a green seal. At one time, they made US Notes which had red seals. USNs were made in $1 (for one series), $2, $5, and one series of $100. You can occasionally still find $2 red seal notes in circulation. Here are a couple examples of $2 red seal notes. The first is a series 1928G and the second is a 1953. Both came from circulation in the last year or so.
man, i REALLY need to get a PT time job at bank lol they may not be worth a ton, but they are so cool to find!!!
No, they aren't worth much but they are fun to find one. And before anyone says anything, I think all of the red seals I have found at the bank came in night drop business deposits. I think I have found 5 or 6 of them since I started working there in October.
