During the 1980's, when I completed my basic 407-card 1952 TOPPS (52T) set, I searched for these "mysterious" mid-series gray backs.
Back then, they were selling for the price of a common 52T low # card. Billy Martin was about $75. And, since I was a Billy Martin fan, I
acquired 2 of his gray backs.
In recent years, I was offered "big bucks" for these cards. I sold the lower condition card, and kept the Martin shown here.
