After a few inquiries and suggestions we've expanded the listings in the slot card guide and on the ChipGuide for the Palms Hot Shot, Big Shot and Super Hot Shot cards.

These cards have an expiration date printed in the bottom right corner on the front of the card and they were issued approximately every 3 months. We've listed all known dates individually and the ChipGuide has scans for all the different cards we've been able to find so far. If you have any cards we don't have scans of I would appreciate getting scans for the ChipGuide. If you see any dates we've missed please let me know and/or send scans.

Here's a link to the ChipGuide listings for the Palms
