I just listed some very rare and hard(er) to find chips on eBay (7 day listings), including a set of all 4 chips from the Pershing Hotel in Lovelock NV, a set of both chips from the Cave casino in Carson City NV, and individual chips from the Eagle Club in Yerington NV and Town Hall Club in Tonopah NV.

If you want to make a trade/purchase offer outside of eBay, let me know before I get a bid on the item or I can't stop the auction. Update on Desert Inn chips: My $25 Desert Inn (Contact NV) chip has a bid on it, so that one's going to the finish line. Both Desert Inn chips have over 100 views and 9 watchers.
