vestmoriado you know how banknotes look after being washed with the laundry?
CatoblepasBills are made to be able to go through the wash for the exact reason that yours ended up in the wash, people carry them around in their pockets and it’s easy to miss or forget about. The bill might look slightly more worn but it won’t have all the color washed out or anything like that, assuming you didn’t dump it in a load of whites with a ton of bleach. It shouldn’t hurt your clothes either.
jeffwI think the washing resistance is more so to prevent counterfeiting in which people bleach bills and print them to be higher denominations.
breadsmasherI thought it was to make sure when money is laundered it doesn’t disintegrate in the machine
It functions that way as well, but durability for every day use is also a consideration in the material choice. Bills being uncounterfeitable isn’t particularly useful if they’re constantly being removed from circulation because someone left a bill in their jeans when they washed them.
