Two from Arizona, Claypool and Yuma.
I got the MC chips in 1998 From Club member John Long. Dennis O’Neill, from TRK confirmed the chips. All MC chips are not created equal. There are minor variations in the MC on several different orders. You have to look close to tell the difference.

John wrote a research article on the chips that he found, and it appeared in the CCGTCC magazine. I believe it was 1999. I do not have the article in my files. If John sees this post he might be able to post it.
