JK0093PS,Sg 16b,1d Red,plate 96. A superb used Archer Experimental perforation from Die 1. Cancelled with a Double ring date stamp. December 4th 1904. Superbly centered with full perforations and no faults. Comes with B,P,A. Certificate. Almost certainly Unique. Catalogued at £1,250.00. for well centered examples without this usage. All Queen Victoria issues except the SG172 Id Lilac were put out of circulation on the 1st June 1901. Archer trial perforations were put to press from 1850. This make this stamp some 54 year before actually used. Truly remarkable.
