3d olive-green Die II Inserted 'CA' Monogram single ACSC 13(1)za (SG 37da variety) alongside 6d pale greyish-violet Die II block of 4 (the scarcest of the Harrison shades before introduction of the Die IIB plate, light stain from wax seal on the reverse) & single tied by Sydney cds of 28JE21 to oversized cover (280x123mm) to Congoleum Co in Pennsylvania with printed 'No Dutiable Matter whatever is con-/tained in this letter' at upper-left, some soiling/minor stains, Cat $3000+ for a 3d Monogram mounted mint single (not priced used) and 6d used x5 singles. A spectacular showpiece for any collection of Kangaroo stamps, "usage", or postal history. The rate was 3d per ½oz foreign letter x11, and the envelope presumably contained a sample of congoleum (linoleum flooring). It could have been sent at the Samples Rate of 3d per 4oz but is not endorsed for that rate & its use is unlikely because at 2/9d the envelope would have weighed an improbable 44oz! The rarity of commercially used monograms is beginning to be appreciated. A used example of this 3d monogram sold at our auction of 21.2.2024 for $1140 but, correctly used in-period on commercial cover, is another level of rarity altogether. By comparison, a £1 grey is catalogued at $575 used but at $5000 on commercial cover (supported by a recent sale at that level of the only known usage on a similarly-oversized cover). The comparative mounted monogram price ($2250) and the realisation for a commercially used one would support an on-cover catalogue value of $20,000+ for this item.
