I'd agree with Greg's sentiment regarding the grading of low grade gray backs and high series. You'd have to have you head examined if you don't belive high series are available in the same quantities. If you prerouse a local you are likely to find none, at the national you are likely to find 3 or 4 dealers with them one being 707 sportscard museum.

As far as the gray backs, yes they were printed first, but I'm not sold on the leftover stock idea. They key to grays being printed first is the Frank House yellow tiger variation and error. However they sometimes have a muddled or grayish front which previous series did not have.
