Just tried Don's suggested search and got 1161 items. BUT, many of them were not chips (I only scrolled through the first 200 and would go nuts looking at all the ashtrays, matchbook covers, elvis albums, etc.)!!

Someone (wish I could remember who so I could give proper credit, but I can't) suggested the search

casino chip* or poker chip*

(in the old search format). I have been using that with a consistent return of around 400 chip only items (not all casino chips, though, as this also gets antiques, advertising and a few other miscellaneous chips; anything which the seller labels as a casino or poker chip). Tried it this morning and found 417 items. After puttering around a little more, I found that in the new format

(casino,poker) chip*

got me about the same results (actually, about 10% more items -- 460).
