I don't collect paper money unless I just stumble upon something, but I always check my money when it is handed to me for stars. I got this from the ATM yesterday. I know people collect serial number patterns, and I thought the six consecutive 7s was neat, especially since 7 is probably the most popular number. I know it's not probably not enough of a pattern to be collectible though, and it is definitely circulated.
Not too special???? It has 6 consecutive 7s, it's definitely worth more than $20 --------------------- Nice note!
Only 3 numbers make up the serial number. As opposed to a binary, where only 2 make up the serial number.
