½d green Plate 2 lower-right corner block of 4 with the lower units Imperforate at the Base ACSC 1Ab, the second unit with Excess Colour at Lower-Right ACSC 1(2)m, a few characteristic irregular perfs, ironed-out diagonal crease in the margins well clear of the stamps, lightly to very lightly mounted, Cat $15,000+. [See also Lot 7 and 8] Provenance: A Rasmussen Jack Cato Herbert McNess Arthur Gray, Lot 95, sold for US$7,762. Julian Sterling Part 1, Lot 2, sold for $11,435. Stuart Hardy's block of 6 with three error units sold for $16,300. This is the block illustrated in the Australian Commonwealth Specialists' Catalogue at note 3, where it is stated that four Plate 2 sheets were affected, creating 48 examples of the error. The ACSC identifies 29 of the possible 48 examples, of which four monogram pieces - comprising two singles and two blocks of 12 - are stated to be institutionalised (one of which is Greg Pope's front cover illustration). This block of 4 and Stuart Hardy's block of 6 account for a further 5 units, bringing the recorded total to 34 of the 48 affected stamps. The ACSC lists the Excess Colour at Lower-Right variety at Pos [2R48] only. On this block the variety is present at Pos [2R54]. Greg Pope at page 73 shows that both positions had a similar colour flaw.

Provenance: 'Besancon' Part II, Lot 3587, sold for SFr968. This block is of far superior quality to the Morgan Collection Die I corner block of 9, with the characteristic creasing and a small tear in the upper margin, that sold for £2400. As an inter-pane piece, this is also a more significant item.

NB: the ACSC does not record or price the monogram pieces. Provenance: Rodney Perry auction of 11.9.1974, Lot 52 as a block of 12, estimated at $375 but unsold! Rodney Perry auction of 28.4.1976, Lot 64 as a block of 6, sold for $200! Status International auction of 26.10.2017, Lot 938, sold for $15,790. Private transaction. The Australian Commonwealth Specialists' Catalogue states that a complete uncut sheet of 480 was discovered in 1964 and was subsequently divided into numerous blocks of varying sizes. The upper Plates A & B had no monograms. Peter O'Rourke owned a Die II block of 48 (12x4) from Plate D with both monograms. The present item is the unique Die I 'JBC' Monogram piece, from Plate C.

1d red Die I Plate B with the Watermark Sideways (Crown Pointing to Left when viewed from the face) ACSC 2Aab(B) in a No Monogram corner block of 6 (3x2) from the left of the sheet, Pos [L50] with Break in Left Frame by Foot of the First 'A' of 'AUSTRALIA' ACSC 2(B)i, the upper-right unit with a small and insignificant gum blemish otherwise superb unmounted, Cat $45,000 in footnote 2. Royal Philatelic Society of Victoria Certificate (2013) states "crown pointing to right when viewed from reverse". This explains the incorrect classification as ACSC 2aa on the Certificate. Editor Geoff Kellow has confirmed to us that the ACSC listing refers to the watermark as seen from the front of the stamp(s). The unique Sideways Watermark No Monogram piece: the Australian Commonwealth Specialists' Catalogue identifies only two 'monogram' pieces with Sideways Watermark: this No Monogram block and one 'CA' Monogram block of 6: see Lot 16. Provenance: Stuart Hardy, Lot 29, sold for $37,280. 'Chartwell', Lot 469, sold for £18,000. Stuart Hardy loved to tell the story of how he acquired this gem. Back in the speculator-driven 'stamp boom' of the late-1970s and early-1980s, a dealer used this one-of-a-kind block to entice Stuart to part with his sizeable holding of unmounted Coat of Arms sets, that he had bought from the Post Office as new issues!

The ACSC states that varieties punctured Large 'OS' are worth double the unpunctured stamps: on that basis, Cat $3500 for a mounted monogram strip of 3, $240 for two mounted varieties, and $85 x31 for the other unmounted singles = $6375+.

The Australian Commonwealth Specialists' Catalogue does not list any monogram pieces for the 1d Die II with Watermark Sideways. It is stated in footnote 2 below ACSC 2 (Die I) that "One CA Monogram block of 6 exists", which we believe is a reference to this Die II block. The only other Sideways Watermark 'monogram' piece listed is the Die I No Monogram block of 6: see Lot 11.

Provenance: Julian Sterling Part 1, Lot 41, sold for $825. The Australian Commonwealth Specialists' Catalogue does not mention that variety 'g' is present in the 'CA' Monogram strips; presumably these should be priced the same as the 'JBC' Monogram strips ($3250), which also include a variety priced the same as 'g'; see the next lot.

Far superior to Peter O'Rourke's similar strip - toning & one unit mounted - that sold for $3800. This is a technically important piece, being a precursor to a later substitution. In early Third Watermark printings a more advanced state of the flaw on Pos [L55] included a 'comet trail' impinging on the Western Austalian coast: ACSC 7(1)ka, not recorded in a monogram strip of 3. This unit was subsequently replaced with the the Die IIA Substituted Cliché ACSC 7(1)kb, Cat $37,500 in a monogram strip of 3.

3d Die I imperforate plate proof in black on ungummed unwatermarked coarse wove blue paper ACSC 12PP(1)A, marginal block of 4 from the left of the pane with vertical jubilee line at left, margins large to huge, all but the upper-right unit with areas of the design poorly printed which is a characteristic of this proof, with none of the creasing and other faults that are usually seen, Cat $2500+ for two pairs. Provenance: 'Besancon' Part III, Lot 3742, sold for SFr850. Arthur Gray's block of 4 - Die I/Die II but cut close at right - sold for US$2875. The Morgan pair sold for £1320. A single sold at our auction of 14.4.2005 for $1745. This item was described in 'Besancon' Part III as "on blued granite thick safety paper, worn and with surface rubbing". We do not agree with this assessment: the block is actually in very fine condition; what may look to be "surface rubbing" is merely where the design did not print properly. The uneven impressions strongly suggest that this was in the nature of a 'makeready proof', a trial sheet made by the printer, JB Cooke, to check where elements of the plate required technical attention. The paper does not appear to be "blued" or "thick" but is a consistent blue colour front & back, and of ordinary thickness. While there are obvious fibres in the paper, it is not what the Swiss would call "granite paper". We are unsure what was meant by "safety paper", but there do not appear to be any special security features: the paper used was likely the cheapest available for the purpose.
