Ron I have not been involve with any of this before, but from the little I get from your post, I think you need to forget all the input and do what is right for you. Put them on ebay and let the bidding begin.
If I had a lot of individual chips to sale I don't think I would try to do that here, because of all the e-mails and side deals of these combinations for this price versus this group for this price. Too much hassel and potential for people thinking you are favoring him over my offer. This may be where you are now. Good luck --
Treat this like all the rest another 2 cents worth of advice.
