These are the new cards being used at all Landry owned Golden Nugget casinos except that the cards that showed up in AC have a manufacturer number on the top right corner of the reverse (092001) which the earlier cards that came out in LA, MS and NV didn't have. Otherwise the cards are identical front and back.

Not sure if anyone noticed but Golden Nugget is using different player number prefixes that I'm assuming indicate where the player first signed up for a card like the Harrah's cards. I have a contact at Golden Nugget and I'm trying to get a list of what the prefix numbers represent.
