T206Collector...does wonderful grading of moon rocks. I tried to have my moon rocks graded by SGC, but they wouldn't do it. GAI will authenticate moon rocks, but they always slide around in their holders. Seriously, for moon rocks, it has to be NASA. Also, NASA has some great authenticated "space worn" cards -- like pieces of Neil Armstrong's boot for their "One Small Step For Man" series. The Apollo 13 series is terrific, too. I love my NASA rocks and cards.
