Where do you find info on a 1996 edition top five drivers metal Dale Earnhardt Sr. trading card?

I have the set of (5) five unopened cards altho the metal box is not in perfect shape and has been opened. Set includes Terry Labonte (1), Jeff Gordon (2), Dale Jarrett (3), Dale Earnhardt (4), & Mark Martin (5). To find info, I 'googled' it. Lots of answers to choose from.
