Gene - I only know what I was told by a friend who sold it to me. He is a pit boss there and said that they got new chips and someone noticed the error. They immediately pulled and checked EVERY chip in the house and found a few errors which were destroyed. A few weeks later someone was trying to turn this one in and he bought it before it hit the cage. He has not seen any more and I have not heard of anyone else having one. Do you have one?
