1876-85 BROAD STAR PERF 11½-12½: 6d Prussian blue as SG O25 horizontal pair Imperforate Vertically with a separation fault at right, light squared-circle cancels. Unlisted by Gibbons. Ex John White. RPSofV Certificate (1963) as the then SG 425 states "imperforate between", which is true but our assessment is that it is also imperf at the sides. Absent from Gary Diffen's collection, and believed to be the only recorded example.

Grade B (Image1)

Estimate AU$1,000

1876-85 BROAD STAR PERF 11½-12½: 6d Prussian blue as SG O25 but Imperforate, good even margins, very lightly cancelled. Unlisted by Gibbons. Absent from Gary Diffen's collection, and believed to be the only recorded example. It might be thought that perforations have been trimmed from all sides of this stamp. However, stamps with perforations clear of the design on all sides are extremely elusive and we consider the likelihood of perfs having been removed from this stamp to be extremely low. We share Don Pearce's confidence that this is a genuine error.
