Turns out there are two variations of the 2nd issue slot card used at Jackpot Joanie's and Winchell's Pub & Grill in Las Vegas, NV. These are the all black cards used before the yellow band was added at the bottom for the player info printing. What was discovered is that when the first batch of these cards were printed apparently the reverse was upside down compared to the front and they supposedly quickly replaced the cards with cards where the back was right-side up (i.e. normal). I added the card with the upside down reverse as the 2nd issue and bumped the original 2nd and 3rd issue numbers up one. The new info will appear on the ChipGuide soon.

Here's the scan of the card I'm talking about
