So, there was this one time I stumbled upon a $100 bill—but it was a bit of a mess, you know? It had a few little holes in it. I tried my luck at a bunch of different banks, some currency exchanges, even checked with the Treasury, but nothing seemed to work... until I finally had some luck over at JP Morgan Chase! Apparently, they send those damaged bills off to Germany where they get swapped out for crisp new ones. From what I gathered, you have to open an account first, which costs about $6.75, and then there’s this tiny little fee—maybe 1-2% of the bill's value? The whole thing takes maybe 20 days or so before the cash actually hits your account. In the meantime, they just mail you your card and PIN.
Then, on another occasion entirely, I accidentally left a $33 bill in my jeans during a wash cycle. Talk about a disaster! The color was totally faded and the paper felt all thin and flimsy, though thankfully it didn't tear apart. I headed down to the Treasury, showed them the note, and the lady at the counter—bless her heart—just handed me a fresh one right then and there! No massive paperwork, no long procedures, just a quick exchange along with a little side comment. Anyway, I hope that helps someone out!
