Attack? Surely not from a member of the Bar. I'll be in Las Vegas on the 14th of this month, so I won't make it to this year's convention. You are correct in assuming my chip is in better condition if yours has had any use at all. The condition of mine is almost pristine. A scan of the chip is below. I'll trade you for a Nevada chip of equal TCR value if I don't already have it. I have no idea what the Sahara Dunes chip is worth but you probably do. I trust you (I think). Email me if you're interested. If I don't hear from you, I'll keep it as a monument to my lack of knowledge.
