No clue on the value, but here's my .02:
When I worked as a team leader (basically a shift supervisor) at a grocery store, I had the opportunity to sort through thousands of dollars of bills each night when I would count cash register drawers. I bought the older and star notes that I found because I thought "why not?" They were neat and they didn't cost me anything over face. True, nothing I found was of any consequential value ($5 53-a, $5 34-b, 2x $20 50-b, $50 34, all very wrinkled), but I'm likely to never see anything like them in circulation, ever again. If you can afford to set aside $10, I say go for it. Perhaps in 20 years or so it'll go up in value as new collectors enter the market or older collectors start a new series. If I were ever in a situation where $100 was absolutely needed to pay the bills, I would spend my currency collection with a heavy heart, but for now I can afford to hold onto them, so I do.
I would definitely keep that nice $10, even it's not worth any more than face.
