Roo FU 1s Emerald 2nd WM CA Monogram pair CDS "SHIPS MAIL ROOM - sYDNEY - N.S.W. - 4JA17". As for the 2.5d Monogram block of 4 I have listed, this Used 1s pair is difficult to value because a used vertical pair with the monogram intact is not something one would normally expect to come across and, probably for that reason, no CV for Used is provided in the ACSC. However, arguably, a used Monogram pair is much scarcer than MUH or MH examples with an obvious, although different, parallel being the used CV of 2 pound Roo compared to the CV of 2 pound Roo over printed Specimen. The CA Monogram at the bottom of this pair has has had small lower portion of the Circle cut off which detracts from its value.
