What Key Cards Should Be Graded
I saw a thread on another board discussing whether or not a 54 Topps Aaron should be graded. Someone made a statement that it is a "Key Card" and should be graded.
In the boards opinion which cards are "Key Cards" and should be graded?
I will start with the obvious 1952 Topps Mantle.
