Could any of my pro wrestling items be worth some money now or in the future?

i am a huge wrestling fan, and i collect wwe magazines and cards and etc ...i was wondering could cards from wcw be worth something...i have cards of stars like chris benoit, eddie guerrero, brian adams, sting and others . the cards came out in 1998 and are in great condition!!..plus i also have a wwf lita bobble head that came out in 2001...so just asking could any of those items could be worth something? probably in the future?
