The First Printings of the Halfpenny Green Queen Victoria Keyplate of Lagos 1885-1886
- There were a staggering 42 printings of the halfpenny stamp made between 1885 and 1902.
- There were 49 printings of the 1d carmine made between 1884 and 1902.
- The period before 1887, when the earlier colour changes were issued.
- The period from 1887 to 1900 when plate 1 continued to be used.
- The period from 1900-1902 when plate 2 was in use.
- Any stamp cancelled with an 8-bar oval killer will likely be from before 1887.
- Any mint stamp that either has no gum, brownish gum or crackly gum is likely to be from the period before 1887.
- The last three printings before 1887 will have the later double gum and these will be more difficult to identify with certainty.
