I noticed The Chip Rack and The Official U.S. Casino Price Guide do not include this $500 Maxim chip. An individual e-mailed me several months ago wanting to sell this chip (he had five), but he was asking at least face value. He stated he won them while playing at the Maxim and since the casino closed the chips are non-negotiable. I was definitely not willing to pay face for the chips but thought it may be a good chip to include in the price guides.
