    Description

    HI all!
    My name is Mark Lyon, and I’m a member of the International Meteorite Collectors Association, member number 6752. My business model is to buy in bulk and turn over inventory quickly (often through no-reserve auctions) giving you the best possible prices.
    When you finish looking at this, please look at my other no reserve sales and auctions, and feel free to contact me if you don't see exactly what you are looking for.
    Up for sale here is a  beautiful 20.80 gram slice of NWA 13951 "starry night" lunar.
    I am going on vacation next week so anything that is not paid for by Sunday night (US time) might not be shipped until after the following week's auction.
