The first New Zealand coins were issued in 1933 and included the Threepence, Sixpence, Shilling, Florin and Halfcrown coins. The Penny and Halfpenny were first issued in 1940. Did not have much much luck finding any pictures.
The Florin was introduced into the British currency in 1848 as a tentative step towards decimalisation which was not realised for another 120 years. A Florin was worth 24 Pence or two Shillings or one tenth of a Pound depending on your frame of reference. One tenth of a Florin was equal to 2.4 Pence in the predecimal currency, for which there was no equivalent coin or combination of coins. In the British decimal currency, a Florin converted to 10 New Pence, so one tenth of a Florin converted to One New Penny.
The New Zealand Florin (Two Shillings) was first issued in 1933 and last issued in 1965. The most valuable New Zealand Florin would be 1936 coin. A distant second would be the 1940 and 1946 coins. The 1946 coin with the value shows the kiwi with a flattened back. It should be noted that the valuable coins only have the high value if the coins are in "mint uncirculated" condition.
