Like Pat said, they should be fine, as long as they were kept out of the weather. But do check them for little holes, or sawdust on the ground around them. Little beetles like pine bores, do a really bad number on them, and they are useless, except for fire starters.
I lost a bunch of shafts to those little @#*&^#!!'s!
I don't worry too much about them up here in Montana. Not that they aren't here. Just not as climatically friendly, for them as in Florida.
go ahead and try them, but check for tiny little holes, and the dust on the floor.
