New Zealand ten-cent coin

The New Zealand ten-cent coin is the lowest-denomination coin of the New Zealand dollar. The 10-cent coin was introduced when the New Zealand dollar was introduced on 10 July 1967, replacing the New Zealand shilling coin. In 2006 its size was reduced as part of a revision of New Zealand's coins, which also saw its alloy become copper-plated steel.

1967 to 2006

On 10 July 1967, New Zealand decimalised its currency, replacing the pound with the dollar at a rate of one pound to two dollars and one shilling to ten cents. The 10-cent coin was introduced to directly replace the one-shilling coin.

The coin was made of cupronickel, 23.62 mm in diameter, and weighed 5.66 grams. It included the words "one shilling" for the years 1967, 1968 and 1969; this was dropped in 1970.

2006 onwards

On 31 July 2006, the new 10-cent coin was released alongside the new 20-cent and 50-cent coins as part of the Reserve Bank's "Change for the better" silver coin replacement. The new 10-cent coin had the same reverse as the 1967 to 2006 minted coins and the same obverse as the 1999-onward coins, but the coins were reduced in size. The new 10-cent coins are made of steel, plated with copper. The new coins are 20.5 mm in diameter and 3.30 grams in weight. They have unmilled edges. It also appears that the new coin has taken on a possible new feature located between the tongue of the tiki, this feature is are two small letters engraved into the coin, these letters are J on the left side and B on the right.

The old 10-cent coins were demonetised on 1 November 2006.

gollark: Well, I would hope so.
gollark: But JS uses double-precision floats for everything, which can represent up to 2^53-1 with no loss of precision, so it's fine***.

gollark: I mean, they do, but not full-color ones, just ASCII art.
