Zanzibar 1926-30 12c black/green Postage Due error, SGD7/a Egypt stamps gave the British the slip2500. 00 Zanzibar 1926 30 12c black green Postage Due, VERTICAL PAIR from R4 5 1 on the sheet (lower left corner), the upper stamp exceptionally showing the error "cent. s", lightly cancelled by complete "JA 7 31" circular date stamp, which barely impinges on the lower stamp, D7 a. A very fine used pair, particularly high quality for this issue. There is some trivial discolouration (as often seen with this value), but one of the best quality examples
