I just finished adding more rare slot cards on eBay, including the rare MOOCHER card from the original Palms Casino in Las Vegas. There where only 10 of these cards ever made and they were only given to high profile customers who had to return the cards when the left the property. The last one of these on eBay sold around $400 a few years ago!

Here's a link to all my current auctions listed under the SLOTCARDEXCHANGE on eBay. There's some pretty interesting cards listed, including an error card with an extra magnetic tripe on the front and a Plaza card signed by Jackie Gaughan!
