Hello, can someone help me make a decision on whether this is worth keeping? If it was a lower denomination I would just keep it but since it's a $100 I'm not sure because I don't really know the value of it. Is it worth $101 or $120? If I try to sell it what should I expect? Or should I just spend it? It does have a crease down the middle & a little bend in the corner but it looks decent. Thanks!
