If you compare this PSA 7(OC) to the PSA 2.5 below it, you can clearly see that the PSA 2.5 has bigger top and bottom borders.

Now there is one thing I want to point out here: according to Ted Zanidakis, the Mantle was printed on the uppermost left corner on its 72-card sheet. Therefore, some Mantle cards may be slightly narrower than 2 1/16, while others may be slightly wider than 2 1/16.

Now it's a bit difficult to tell if this PSA 7(OC) is undersized left-to-right due to the centering issues. I did compare it to a couple of off-centered examples and I didn't see anything.

So, is this PSA 7(OC) trimmed? Maybe. Maybe not.
