If you've concluded that this bidder appears to want to purchase your chips for resale, then it looks as if he, rather than you, may find the final resting place for your chips (until those buyers resell them and continue the cycle). Enjoy your profits.

Perhaps a better way to find a good home for your chips would have been to offer them here, on the ChipBoard, first. This way you could weed out the chip dealers and give a higher priority to the collectors. If you feel that strongly about the future home of your chips, you can end the eBay auctions and try this venue first. All perfectly acceptable. Good luck with whatever you decide.
