Twenty Cents, Coin Type from Fiji - detailed information

In 1969, Fiji changed to a decimal currency. The currency structure was the 1c, 2c, 5c, 10c and 20c coins, and the $0.50, $1, $2, $5, $10, and $20 notes.

In October 2008, the issuance of 1 and 2 cents coins ceased. In February 2009, a new set of smaller size and lighter coins were introduced. The larger size coins of 5, 10, 20 and 50 cents as well as the 1 and 2 cents were demonetised in April 2009.

According to Krause:
From 1969 to 1987, twenty cent coins were copper-nickel and measured 28.5 mm, with a mass of 11.31 g.
From 1990 to 2006, twenty cent coins were nickel-plated steel and measured 28.5 mm, with a mass of 10.5 g. (except the 2003 South Pacific Games Commemorative, which is listed as copper-nickel with mass of 11.24 g.).
2009 and later issues are nickel-plated steel and measure 24 mm, with a mass of 4.68 g.
