I don't really dabble in notes, moreso just coinage... But that said I always look at the serial numbers for something interesting, but I never find any even remotely different

... And that's looking over quite a few bills, lol.
And then yesterday I was going through $1K in 20's and found this one, I doubt there's any premium but I figured I'd ask the pros.. As this is definitely the closest to a radar I've found... Too bad that "15" in the middle wasn't an "11" or "55"... Uugh.... Soooo close.... Lol. But it is neat....
