"The opinion sellers"
So my experience with the opinion sellers is they are all over the map with some of the odd/less seen by them issues. I have seen cards with the same numerical grades that non hobby novices would be able to clearly identify 1 as clearly better condition. I have seen trimmed cards in holders with number grades. I am not familiar with the particular issue in question so have no personal opinion to add as to if they are trimmed or not.
