like $1 a chip on ebay selling as a lot. There are only a small handful of people that collect this type of chip. Even with even numbers of each color you would be lucky to get 25c a piece.
Lots like this change hands between dealers at 5c a chip. If you want to sell 10 sets, I will pay $25 shipped.

"Also, if you're interested in doing me a favor and buying all at 25 cents a chip, thanks but no"
Sorry if you were offended by my offer last time, but I see you still have the chips
