What does centering really mean?
Does it refer to the picture being in the center of the stamp?
Yes. Most stamps (at least classic stamps) had a frame around the design that makes it easier to assess. Most of us just eyeball the margins, looking to see if they are even or not. Very fine centering means almost but not necessarily perfectly even margins. Extremely fine means perfectly even so far as one can tell with the naked eye. Fine means, off center but not too badly. And so on down the line. The samples in the front of the catalogue don't bother to go below fine/very fine, doesn't even illustrate a "fine" stamp. It has a category of f/vf below the "very fine," shows slightly off-centered stamps. The catalogue value is pegged at very fine.
In theory, no "real, serious collector" is supposed to ever bother buying off-centered stamps (or at least never admit in polite company at the stamp club that he has done so), but in practice, most of us plebeians are willing to compromise our high principles. . . . Well, at least I am. But whaddaIknow?
