New Guinean mark

It was equal to the German Mark, which was also legal tender in the colony.

These coins were demonetized on 15 April 1911, in exchange for the German Mark, the only legal tender after that date.

In 1914, during World War I, German New Guinea was quickly occupied by Australia.

That year, the Australian authorities issued Treasury notes denominated in marks.
