Nothing, it's just an item that was included in the original mining game in Diamond/Pearl/Platinum and that wasn't removed in this one. Normally it would give the player a chance to catch Spiritomb, but that feature doesn't exist in this game.

Just sell them whenever you can. They won't have any other use.
