Hi Larry - since you're only putting them in there as freebies for others, I don't have a problem with it. I would request that rather than putting them in pages, if you put them in an envelope, clearly labeled that they're non-casino keys & free for the taking. Although I haven't published the listings yet (hopefully tonight, time permitting), you are toward the end of Group #14 and I'm not sure there are any non-casino key collectors following you. You might just want to offer the lot on the message board. It's your call.
Thanks,
Jim
