GB 1902 Edward VII Board of Trade Perfins Mint Set of 8 to 1/-

Mint set of eight Edward VII Board of Trade Perfins from ½d to 1s. The 2d indicates a reversed perfin layout which happens when sheets were fed into the perforating machine face-down or sideways; a scarce variation. Finding official government department perfins in mint condition with original gum is quite scarce as they were intended for internal office use and rarely survived unused.
