Doug AllenIt is the not the size it is the cut and the edge. The cutting process for T206s and other vintage cards is much different than it is today. The problem is too many collectors depend way too much on whether or not a card measures up as opposed to learning what the cut and edge should look like on a T206.
Regardless of whether or not you like or dislike PSA or SGC I commend them on understanding these nuances. I measure my cards and if they are within 1/16th of an inch I move beyond size to the cut and the edge.
