Casino playing cards are finished to 0.05mm margin of accuracy, this means that cards produced six months ago from a different batch will marry identically to those produced in a new run today. That is according to Roland, who make the machine that finishes 90% of cards used by Las Vegas casino's. So I guess its unlikely that you will find a deck with a difference in a six deck shoe.

Once every four years IPEX the world trade printing show is on here and I have been to it often. I have seen the Roland machines in action there and its like waching something from Willy Wonkers Toy Factotry, quite marvelous. http://www.youtube.com/user/RollemStuart/videos

Ever see the movie Kaleidoscope ?
instead of the cutter.....we want the plates ?

they actually pulled that scam in real life about 10 years or more ago in south Africa.

the guy who marked the plates never used then, as the story goes.

he sold the secret of the marks to people....so other people were able to read the marks in casinos.

to his dismay, the casinos found out and tracked the secret down to him.

Yeh it was a good film and yes I know of that case.

At the IPEX one can see the latest in secrurity printing, inks etc. I seen some beatiful casino chips there, just hologram security stickers on them but they were cool. You see the casoni cloths being printed, most start white to my surprise. You could spend a week there and not see everthing. Lots of little interesting things.
