I read a newspaper article once (yes, I'm that old) about an American forger who was making phony $20 bills. He was making them by cutting the corners off of legit 20s and pasting them onto the corners of legit singles. So, he was ruining $21 worth of valid currency to create a counterfeit $20 that fooled literally no one.
