Why not? You can always spend it later if needed. Maybe keep it until you get one with 6 4's in it and then 7 4's and so on.
today i got 2 bills with cool serial numbers, one is 01238835, and the other one is 21991119. both on 2003A $1 bills.
the 54441 got a 98.1%, the 01238 got a 95.9% and the 21991 got a 97.1%. nobody wanted them at auction, so i entered them into wg? marked them with my stamps, and spent them.
I picked up a 2003A $1, #33333000. It has a coolness factor of 99.51%. The coolness number site has some interesting stats on serial numbers that I didn't know.
when i get bills in change, the first thing i do is look at the serial numbers. i can usually pick out the ones that are probaly going to be cool. then i go to coolnumbers, and i find out that there were more cool serial numbers i didn't even see! that website is great.:high5:
i have been carring a one dollar with the number 14444446 for several years. i never heard of the coolnes factor itrates 99.05.
I also have dollar bills with serial number.04440222-90729207-19011910-44344347-83421384-77664646-19411029-7766467-33337892-66202505-88457547-13131366-73444373-03766307-57957977-77000303-05406546-24735186-36262377-44505505- $5-33733333
