today in change I got a beat-up $1 bill with the serial number: B81881881E my thoughts revolve around it having just 2 numbers as well as being a repeater do I have anything? or should I just put it back into circulation?
Pretty cool! The only thing I found was a 20 with 6 2's in a row. I was young and decided to spend it. I have no idea if it was valuable or not. I'm not a paper collector, but I always look for radar's and stars.
Some collectors consider this a binary, while purists only consider 0's & 1's as binaries. Unfortunately, it's not really a radar or repeater......kinda something in between. If you like, then that automatically makes it a keeper.
