Bonsour Monica,
You might also try the CC>CC chippers chat site:

The Chipboard.com

and put a post on the site. Of what you are looking for. There are thousands of chip collectors out there and in the CC>CC club. That's what they love to do collect casino chips and tokens. I would think 1 of them would have a extra 1 that they would part with.
Good luck,
Dan
