Ok, most of the casinos I've been in I've noticed what was said above about the black vs. A on the peek.
BUT...at a casino which is my fav, I actually have a supposedly "used" deck. Hole punch through the cards.. and even a time/date stamp on a card insert with torn jokers....
And the casino uses the mirror peak. The cards DON'T have the black in the corners on the 10s. So they must be seeing the card value through the mirror, right? At least they arn't seeing black v. A.
