Size Variation of 1953 Bowman Color
 

I recently received some 1953 Bowman Color cards back from PSA that were returned unslabbed with a flip indicating that there was evidence of trimming, but I honestly do not think they were. I am wondering if I should resubmit them.

How much of a range of size have you seen for 1953 Bowman Color?

Since the factory cut size of these cards varies, how could a determination be made of whether a particular card has been trimmed, or if it is simply a smaller factory cut?
