I recently bought a heavily trimmed 1938 Goudey Dimaggio. I have a photo of it below with a regular sized 1938 Goudey card behind it.

My question is: How heavily can a card be trimmed before a grading company will no longer encapsulate/slab it? I know that it's different for every card, but I was just wondering if anybody has experience with this? Is there a general rule?

I reached out to SGC customer service about it and was told I needed to send it in for grading to find out.

Thanks in advance.
