If you want to discuss years of poor terminology, please remember that every series 1 from 1958 thru 1969 had 110 cards (some years were 1 to 110; others were 1-109 with an extra copy of checklist 1). So, checklist 1 would be printed 4x (albeit most had subtle variations), 44 cards cards in the print run were printed 3x, and 65 cards were printed 2x.

Every series 1 during those years used a similar print pattern (4 rows 3x, 6 rows 2x) and yet SPs are not considered (i.e, labeled) in those years except in rare circumstances (e.g., 1966 Mantle is called a DP).

Moreover, as many of us who read this forum have found out, some cards long considered as SPs truly were not.
