I know this falls under a couple different fancy serial number categories but not exactly sure if it is worth keeping in the condition it’s in. Does it have any value? I would appreciate any advice. I typically just collect coins
I'd guess you could find a serial number collector willing to pay you a few bucks for it, even with the damage.
Welcome to CT @Sherie . It’s a radar. Some would also include the term binary, but I reserve that for a note with 1s and 0s. The condition and stamp affect the value, but I’m sure someone will want it.
It's a binary radar note. Even with the damage from a tellers stamp it should bring a small premium to a collector of sorts.
