D15 1924-31 George V 4d Dull Grey Green Postage Due Watermark Block Cypher I 28 Perforated Control in fine and fresh unmounted mint condition.

A very scarce control on this value and issue and falling just short of the Post Office fresh grade here with minor gum bend to note that few others would.

Not that there is generally a simple formula to calculate prices but noting retail UM trades at a four fold increase on mounted and the only listed price you will see for such controls is for mounted mint and just a little shy of £200.


Like every stamp I sell this has been fully checked and confirmed by myself as correctly identified and described, not just removed from album where it was listed as such.
