I'd bet many coins and bills that old have value as collectibles aside from their monetary value.
Bills that old would have been extra large sized in comparison to today's bills. Definitely collector items.
You would win that bet.
The collectable nature of older US coins and paper money varies, but folks who have any questions should be careful.
I'd suggest checking with a "reputable dealer", if you know one, (good luck with that BTW).
But the best thing would be to check what your items are bringing at e-Bay. Remember that collectors are crazy in a way. One small variation can sometimes mean BIG bucks when setting a price to sell an item.
