This has been bugging me all day. There is some sort of media that I've watched or read somewhat recently where time travel was involved and based on the time where the person/s reappear their currency can change (like a different president on a $20).
I'm completely blanking on what it could be, but I'm wondering if it was The Man in the High Castle or either maybe from some of the recent Flash comic series? Maybe the Dark Tower series (I'm only through book 5)? I'm blanking on what in the world it could be. Anybody have an idea?
