Yeah, it sounds like the $10x10 bills from 1913 wouldn’t be the ones you’d want to spend at Starbucks. I remember the silver certificates but I have no clue if I’ve ever seen a red seal. I doubt I have.
Someone came into the store a couple of years ago with a bunch of silver certificates that his grandfather had left him.
I told him that he might want to take them to be appraised as they were worth a bit more then face value.
