Need some advice. Going to list this Resorts chip on ebay soon. It belongs to the father-in-law of a person my wife works with. He was about to punch a hole in it and make a keychain!!!

When he heard the potential value of it, he wants to sell and I said I would help.

Has anyone seen one for sale before, and what did it go for? What's the best way to ship and insure this item if it does get sold?

Please let me know your opinion. I never had a chip this valuable. Thanks.
