50 Cent Coins 2006 Onwards

New Zealand’s plated steel coins

In 2006, new and smaller plated steel coins were introduced to replace the older cupronickel 50, 20 and 10 cent pieces.

New Zealand’s plated steel coins are manufactured by the Royal Canadian Mint, in its Winnipeg factory.

Plated steel coins differ from older cupronickel coins which were demonetised in November 2006. During the manufacturing process the steel core is covered with layers of nickel and copper, giving the coin its characteristic colour and surface.

The Missing B error is completely gone but there are a number of coins where it was getting weaker
