I've noticed that there are a ton of used casino cards available for purchase in numerous places, but they are always cheap paper cards. I have never noticed casino used cards that were plastic (other than the Copag WSOP cards). Why is that? Are all of those cards for sale cards that were used for blackjack? I don't play in casinos, so I don't know what cards are used for poker. And do most casinos still use standard index for poker?
