Trimmed or not?

I just got some 1958 cards in that I bought off Ebay and was looking at them trying to decide which ones to send off for grading, this one has what looks like a razor blade cut off the top edge. What is the actual measurement for cards supposed to be, this one measures about 2.503" wide by 3.512" tall.

"trimmed," to me.
The "cut" might even be a thumbnail; somebody trying to
scrape the stain off. (?)
My guess is: Not Trimmed.
