PSA Question
 

Ok is the holder the same for example a normal standard sized card and a larger one like 1952 topps? Is the holder the same size for the 33 goudeys?
Are the cases diffrent sizes for diffrent card issues?

The holder is the same size
 

The interior opening in the slab where the card fits is differently sized for different issues. They have tobacco card, Goudey/PlayBall, '52-'56 Topps/Bowman, and modern card openings (and probably a few more I'm not recalling at the moment).

A standard sized Topps card, a larger sized Topps card ('52) and a '33 Goudey are all slabbed in the same size holder. Some larger issues like Exhibit cards and postcards get larger holders.

Does any one know if it's the same for bgs?
