There is basically no correlation. For example in the last year I've sold what should be some very common autographs on very common cards at decent prices, simply because of what card they were on. For example, 1963 Willie Stargell autographed card for $1,000, 1965 Catfish Hunter autographed card for $550, 1951 Bowman Mickey Mantle autographed card for $8500 (when it was signed on basically the equivalent of a PSA 2 to 3 quality card) and several others that escape me at the moment. Some other examples that come to mind are the 49 Bowman autographed cards of Hodges, Ashburn, Doby, Lemon, etc. very common autographs AND very common cards, but put the combo together and it sells at a premium.
