Yeah, I cracked it..
I did it twice before and got the same exact grade before.. so I was happy.. And the grade was accurate.. This card fit so perfectly into the csa slab I decided before buying it that it wasn't likely trimmed.. and upon holding it up to other cards it measures fine.. I have heard they've graded a fair amount of trimmed pre-war stuff.... but the post war stuff is easier to tell because it fits snugly into their standard holder/gasket..
