Hello, one more from the Gold Coast today and this one from a 1918 GV issue. 

An interesting set of stamps  from the 1/2d through to the 20 shilling value.  Plenty to look out for and as always it is important to have a good catalogue to help you.

One thing to know is the  Die types of the Key Type design.   SG will explain this well but one very clearly distinction is the  angled or vertical cut of the line on each side of the crown above the Kings head -  notation A in this image.

A useful rule of thumb,  although with a few exceptions, is that the  watermark multiple crown issues are Die I and watermark multiple crown script are Die II.   Always worth checking very carefully as the catalogue prices for Die II issues are  generally much higher than Die I type.
