First of all this chip is not from Mather AFB, in Rancho Cordova, CA. The original base was activated as Mather Field in 1919. And it was deactivated and closed in 1993. I was stationed there from 1976 to 1982. So I know a little bit of the history of the base. It was never known as " MATHER AIR BASE " It was a Strategic Air Command Air Force Base " AFB " The other L mold chips are legit, this HUB mold chip is not from Mather AFB. Just because the the chip was delivered to an address in Roseville, CA makes no sense. This is a Govt. Military operation. The chips used in their Off. and NCO Open Mess clubs would have been sent directly to the base. Military bases did not have illegal gaming operations.
