1956 Topps Mantle Gray Back
 

Can someone explain the gray back mantle '56. What are the other variations? When I look I can't tell. Which are rarer or more expensive? thanks

Hi Anthony- you might get a better response with this on the post war forum.

Thanks Barry, I'll go ahead and post my question over there. Whenever I post I think I need a Huge Banner stating you are about to post to this particular section, therefore, I can get my threads in the proper place.
