Aventine+ Media — On This Day

59 years ago today, New Zealand’s currency was first called the dollar.

On 10 July 1967 — the Reserve Bank issued an entirely new series of banknotes. Each depicted Queen Elizabeth II, a Captain Cook watermark, Māori motifs — and on the back, a native bird paired with a native plant.

Do you remember D.C. Day — or still have one of the 1967 notes tucked away?

Aventine+ Media: The Failed Australian Colony in Paraguay

In the early 1890s, an Australian journalist and union organiser named William Lane became convinced that a fairer society could not be built at home. To achieve this vision, Lane founded the New Australia Co-operative Settlement Association and established the Colony of New Australia in Paraguay.

Among the colony’s most notable settlers was Dame Mary Gilmore, whose portrait appears on the current Australian ten-dollar polymer banknote.

The example here is among the finest survivors of that extremely rare issue: the clasped-hands vignette with bare forearms — Symes Type 1 — a one-peso printed in red, dated 2 October 1895. Only two examples in private hands are recorded by Symes.
