Straits Settlements Queen Victoria 1883-1891 Definitive Stamps

Just bought an entire lot of Straits Settlements stamps off Ebay and one of the sets includes the Straits Settlements QV Definitive II from 1883-1891.  Have the 2c, 4c, 5c, 6c, 24c and 32c USED.  Please see the scan below.

As I have some duplicates, was thinking that it was possible to actually perhaps sell the extra ones off Ebay.  However, I am not so sure about paying a listing price when there is no confirmation that anyone will actually buy these stamps.

Postal Codes and Mail Sorting

A few days back, I wrote about Singapore's Postal Code system and how it has evolved over the past from a 2 digit code to a 4 digit code and finally to the current 6 digit numerical code.  Searched online for a video on how mail sorting is done and am surprised to realise that it is now almost fully automated with computers being able to analyse even handwriting.  Feel free to watch the video below.

 

Queen Victoria Straits Settlements Stamps

Look what just arrived in my mail box.  A lovely set of 4 stamps from the Straits Settlements era from various Queen Victoria definitive set.  Seriously, I can't really tell the difference between all the various definitive especially for the King Edward VII sets.  They all look the same to me.  Anyway, here is a scan of the stamps:

I believe the top row (from left) is a 1882 Queen Victoria Definitive 1(b) 8 cents and 10 cents. This is followed by the carmine rose "THREE CENTS" surcharge on 32 cents.  The last stamp is a 1892-1899 Queen Victoria Definitive III 3 cent brown colored stamp.

Do let me know if I got my stamps correctly defined.
