I searched ebay for the Westerner chip you described and found this closed auction...

As you described it is the 25¢ orange smcrown chip that sold for $877. But this one was sold by a different seller name... asds143. Has to be the same guy as your rumphman57 right? Or a couple of people have them???

Just curious!
