Hello, let’s look at another Malay State. This time Negri Sembilan. 

Negri Sembilan was a federation of smaller states and included Sungei Ujong which was absorbed into Negri Sembilan in 1895.  You might find Straits Settlement stamps on mail from Malaya in the early 1890s with Sungei or Ujong cancels, overprints or surcharges.  All covers with have rather expensive catalogue values.

Negri Sembilan was placed under the British control in 1887. The first stamp was issued in August 1891, overprinting "Negri Sembilan" on stamps of the Strait Settlements, and then in  1891 came a stamp with the drawing of a jumping tiger. In 1896, a series of stamps with the image of a tiger's head was issued – Note: not necessarily the actual stamps shown as various values were issued between 1896 and 1899.

In 1896, the Federated Malay States were formed. The first stamps of the Federated Malay States began in 1900, when the stamps of Negri-Sembilan and Perak were overprinted "Federated Malay States".

Federated Malay States ceased in 1935 and were replaced by stamps of the individual states.

As we have seen from previous States I have shown, the stamps of Johore were used from 1965  with the Arms of Negri Sembilan and inscribed NEGERI SEMBILAN on the orchid issue and  from 1971 we see the Malayasia butterfly issue again with the inscription but in lower case for  “negeri sembilan”

I hope these images help a little.

Certainly an interesting area to collect.   Enjoy your stamps   Michael cddstamps.com
