I have been "given" some old US currency from a friend in exchange for some work I have done. As much as I would like to keep them all I can't. I realize I could just spend it as with any US currency but I have looked and there are some that are worth a lot more than face value. These range in date from 1899 up to 1953 and in denomination of $1 up to $100. There are both gold and silver certificates, consecutive numbered, & "Black Eagles" as they are called. Also several of the so called "horse blankets" because they are so large. Where would be the best place to get a fair price on these so I can recoup some of my "wages"? I would be glad to post some pictures if anyone was interested. I think I have about 20-30 of them. Should I just sell them on Flea-Bay?
