Some don't like to bid on undisclosed reserves. In your case, I don't know if that will be a hindrance, given the rarity of your chip. I just thought I should mention it. Like Von, I don't collect that type of chip. I am just trying to be helpful. I should also mention that, although Don may not like private auctions, there may be plenty of other bidders that don't care or prefer them. I was only trying to offer some explanation why Don may have written what he did.
Good luck on your auction.
