I m a 69 yr. old disabled VietNam veteran living in Las Vegas. I have been collecting some graded coins as investments and because I like the way that a really nice coin looks. Living in Las Vegas I have also been collecting $10 Casino silver strikes and $1 Casino slot tokens for display.Being new to collecting I have some questions regarding graded coins from NGC and PCGS and thought this might be a good place to get some of my questions answered since "Google doesn't seem to help much.
