I see (1923-29) 839 A276
Could you be mis-reading something?
US stamps design A276 is the 1 Cent Washington issue of the 1938 Prexie series and that's very different from these Franklins.
These Franklins are design A155 and the only coils that I see (ignoring the pre-cancels) with vertical perfs is Sc 597. Same view as Nuggethill.
(Vertical perf'ed coils are coils in which the perfs run vertically, on the side rather than bottom and top.)
Does this help?
