I don't collect room keys myself but I did just get a big batch of room key cards with a slot card collection I recently acquired. I just finished going through the cards and added everything we were missing on the ChipGuide. If you get the daily email newsletter from the ChipGuide you would have seen all the new additions when they were added. There were just way too many new additions (140+) to list here. And while I was at it, I did some major cleanup on the room key listings to get them better organized and/or added details in the listings. There were a bunch of new variations of old cards as well as many newly found cards. I have a few people looking through them now and then I'll post what's left on my Delcampe store.
