Measuring Slabbed Cards

You need both measurement and a look at edge quality.

I'm not sure how I'd measure thickness while a card is in the slab. Out of a slab, a $40 digital caliper will give very accurate measurements of thickness, to check for pressing and retrimming corners, you'd want to measure the thickness somewhere in the interior of the card, and at all four corners.
Then you also have to know how thick it should be.
