I have a few boxes of 204 all different slot cards for sale or trade.
These are mostly older cards and would make a great way to start a new collection. Cards are from all over and are dupes from my 4 cross country trips from Boston to Las Vegas.

I will trade for 204 different of your slot and/or room keys. Or if you prefer $20 postpaid.

204 are about the most cards you can fit into a small priority flat rate box.
