Ok this was a good video. Though this guy has misstated a few thigns. First the top 4 grading companies should be PCGS, NGC, ANACS, AND ICGS. Second, a mint state coins is not a coin that has never been touched. A mint state starts off has coins with ware, but can have blemishes, scratches, and bag marks. Third, eBay is ok to use, just watch out for ratings, if they guarantee returns, and never buy from China
