Gilbert MainesIf I understand you correctly, then Mr. Cycleback, an autograph of an obscure player which is infrequently encountered sees demand from specialists who collect autographs by team and collectors who specialize in rare baseball player autographs.
I wonder if there is a counterpart in the baseball card hobby. Specifically those who specialize in rare cards, simply because they are rare. Andy Baran's website comes to mind. But I am not sure that rarity is the primary focus there.
Lots of people seek out scarce cards preferentially, but that is different.
