Australia #278 (SG#281) 3.5d Carmine Red, 1955 Rotary Issue, a VFNH block of 4 Showing Damaged Shading on the Globe of Upper Right Stamp

A well centered and very fine NH block of 4 of the 3.5d carmine red Rotary stamp from 1955, showing damage to the diagonal shading in the globe of the upper right stamp. Unlisted in either Scott or Gibbons, so I have no idea as to whether or not this is a constant variety. My estimate of the value is $5 for the block.

The block offered here grades 80 as follows:

Centering/Margins 50/70

Paper freshness: 5/5

Colour: 5/5

Impression: 5/5

Absence of visible paper flaws: 5/5

Perforations: 10/10
