They do buy baseball cards but I'm not sure from what year. Call them in advance to find out.
It is hard to say I do not know what they are buying but take them in and ask they are really nice guys you may have some they are looking for
Depends on a variety of things such as which players , condition of cards and so forth. I know as a collector myself I am always buying cards myself.
I went there once to have some cards checked out. They weren't worth much. So I put them in my bicycle spokes.
