in the episode, "Are you or have you ever been?", Angel is looking at the Hyperion hotel to set up his new office. he starts having flashbacks about when he was there before. blah blah blah, girl comes into the flashback and she had stolen money in a suitcase from the bank she worked at. the flashbacks were set back in 1952 and at the end of the show when Angel finds the suitcase where the woman had hid it long ago, it has all new $20 bills in it! now, correct me if i'm wrong, but didn't those new $20's only come out a few years ago?
