A second variation of the black 1st issue Starter Card from the original Golden Nugget (Wynn) casino in Atlantic City, NJ was just reported and added in both the slot guide and ChipGuide.

One card has "Good Thru" on the front with a date of 12/86 and 6 lines of text on the back.

The other card doesn't have "Good Thru" printed on the front but has a date of 12/87 and 8 lines of text on the back.

Both AC cards mention "may be" in the reverse text (with the space) where the similar looking Las Vegas cards don't have the space and mention "maybe"

Here's a link to the scans of the AC cards that are now on the ChipGuide
