I don't actually have the chip. It belongs to someone I was in contact with, regarding maybe buying some chips from him. He sent me a few photos of his stuff and it appeared to be mostly new stuff. There seems to be a lot of high denom fantasy and promo stuff. I felt it wasn't what I was looking for so I sort of begged off. He lives a pretty good distance from me. I felt not worth the long drive. I thought the Miramar chip was neat but, the chunks out by the bottom corners cooled my interest. I didn't ask about the flip side. I didn't want to seem "TOO" interested. I think the chip is about 35MM across, perhaps a tad more. The 50 looks inked so I guess the other type was too. I left things on good terms I hope. I never want to burn bridges where chips are concerned.
