I have all of the Overstreet Guides from #9 (1979) on...I remember at the time the top $$$ comic was Marvel Comics #1 for $10,000....Action was only at $8400. This year they're at $420,000 and $600,000 respectively!

I must add that I think the articles in Overstreet used to be more informative...now they seem like fluff pieces.
