Need help with these cards

[mikepro44]

There was a thread talking about these retro cards and how some of them are different based on there look and I can't find that thread. Can someone tell me if these cards are the retro's that are listed in the beckett?There is writing on the back of the cards. I am going to put them in my sell thread but don't know what they are worth. Thanks for your help. Mike
