For a while now my dad has been collecting Omani Rial banknotes with numbers scrawled across them in the hopes of finding all the numbers from 1 to 100 so he can frame them. It's kinda fun, and today I suggested looking through them all, because he honestly had no idea which numbers he was still looking for. Unexpectedly he only has about 10 more to find! Which I'm sure will be the hardest 10, but he's so close!
