1909-10 Watermark Crown over Double-lined A Thick Paper 1d Rose-red and Green Die II Perf 11 mint with part OG, well centred and of fine appearance. While the least rare of the three perf 11 stamps of this series, the 1d is still a major rarity with only a handful of stamps recorded, it is rarely seen offered for sale and when it is, many stamps turn out to be the common thin paper version. It is believed that only one or two other mint stamps are known. BW D79 cat AU$7,500, SG D74 cat £3000
