1952 topps questions

[callou2131]

Any experts out there? One of my Pcs is Luke Easter. He was my moms favorite player while growing up. Anyway I wanted to get a few replacement cards because of condition issues. I picked up a 52 off of ebay. When I got it I saw that it had a black back. The one I had was a red back., I know that the Blacks are from the first print run. I have also heard of Gray face cards. When looking at the printing colors, I think this may be a gray face. I am definitely getting it graded. I think it is a strong 7 or may get an 8. Just wondering if the black back gray faces are more scarce, and if they carry a premium? Here are the two cards side by side.
