A Very Fine Used single of the 5d dull purple & chestnut King Edward VII from the 1905-1907 Imperium Keyplates Issue With Multiple Crown CA Wmk On Chalky Paper scarce used example with nov. 21 1906 cancel. This suggests that this value was so issued much earler than Gibbons(1907) or McCaig(1909) indicates. A bit of toning on back, which I would leave alone, as the colors are fugitive on these, so you shouldnt soak them.
