I don't agree with that.. Anyone can ask for whatever price they want which many times makes no sense.
I doubt it, but to a collector that focuses on *star* notes, they may pay a slight premium, but I personally would just spend them. If they were $1 or $5 notes, I'd hang on to them.
You might get a slight premium for them. If I found in circulation I'd keep it but I sure wouldn't pay any extra for it.
