Well...I did pay a $1 premium for it. I'll wash (Gasp!) an' starch it (Ughh!)...and keep it forever. Anything wrong with that?
I had to take a second look at the 20, It looks really worn but still a 20. Good luck with what ever you do with it.
after working at a bank for many years i wouldn't even touch a bill that dirty with my hands. lol who knows what could be on that thing. there are still so many of those notes out there, you can get a better example for a small premium. just my .02
