And there's a guy down at the mall with a machine that can engrave numbers on things just like that number on your chip. What do you think I can get for an error chip, where the number was engraved upside down? Or for chip number 777?

Of all people, you Gene should understand the value of proper marks made by proper people vs. forgeries. The chip shown here has marks put on it with a sharpie. If they were put there by the person pictured on the other side of the chip, I think I've got a valuable autograph. If you put them on, I think I've got a defaced chip. Of course, I watched them being applied. If I bought the CN chip from the gift shop, or from someone I trust who knows it came from the gift shop, I'd believe the gold marks were authentic. And all this controversy just makes them more valuable!

You're in the process of investigating a non-incused Rondevous $100. What is the difference in value if it was a second run for the casino vs. a Borland fake?
