Natal-1876-1 Shiling-(Green)-Postage Stamp-Local Overprint-Illustrated

Shown below is the 1876 Natal 1 Shilling (green) stamp with "Postage" overprint. The stamp was overprinted locally. The overprint is very similar to an overprint used in the first issue of the stamp of 1869, The 1869 overprint is quite rare, only 60 are known to have been overprinted, making the 1869 variety quite valuable. The watermark for both issues of the stamp is a crown over "CC" and both have a perforation of 14. The watermark is illustrated below the stamp face illustration
