At the time of the first Moon landing at nine years old I had recently begun to get interested in mineral collecting. I wrote to NASA asking if they could spare a small piece of moon rock for my collection. They replied saying they didn't have any to spare but sent me a terrific pack of colour photos from the mission and all kinds of NASA publicity material.
Two or three years later a sample collected from the Moon made a tour of British museums. It was displayed under a plastic dome with all kinds of security measures in place. Fortunately, one of the members of the local mineral and mining club of which I was a member was also the natural history curator of Plymouth Museum. He arranged an evening when a group of us came in and were able to handle the specimen. Though there was a certain thrill in handling a piece of Moon rock, the sample itself was actually rather uninspiring. And no, I didn't get to scrape a piece off with my fingernail! Apparently the sample was accurately weighed before it was despatched from the US and would be as accurately weighed on its return!
