I sold 100 of them (50 of each) for around $6-8 each. Chips sold as singles would bring perhaps an extra buck or so. The 'chip set' collector market (as contrasted to the 'chip' collector market) has pretty much collapsed since then (to prices of probably half or less in large lots), although I imagine as singles your chips would probably still fetch $7-10 each.

Hope this helps.
