The Australian twenty-cent coin of the Australian decimal fraction currency organization was issued with conversion to decimal fraction currency on 14 February 1966, [ 1 ] replacing the guilder which was worth two shillings – a tenth of a impound. ( The Australian pound was converted to two australian dollars. ) To date, four different obverse face designs have been used : from 1966 to 1984, the head of Queen Elizabeth II by Arnold Machin ; from 1985 to 1998, the head by Raphael Maklouf ; from 1999 to 2019, the oral sex by Ian Rank-Broadley ; and since 2019, the capitulum by Jody Clark. The obverse has the dedication AUSTRALIA and the year-of-issue on the right hand side, and ELIZABETH II on the leave hand slope.
From 1966 to 1994, the design for the reverse face was Stuart Devlin ‘s platypus. With the exception of commemorative issues, it continues to be the criterion design for the inverse face. [ 1 ] The United Nations 20c was the first commemorative mint issued for circulation in 1995. [ 1 ] Five-cent, ten-cent, twenty-cent, and fifty-cent coins are legal tender up to the sum of $ 5. [ 2 ]
commemorative coins [edit ]
There have been diverse commemorative issues with following reversion face designs : [ 1 ]
Varieties [edit ]
Excepting commemorative varieties, there have been a number of varieties of regular issue coins identified by collectors, on both the obverse and turn back faces. The first of these seen is a highly respect variety show of the 1966 offspring, with a “ wave ” on the top of the bottomland stroke of the 2 in “ 20 ” on the change by reversal grimace. These coins are immediately sold for over $ 200, depending on condition. other varieties of the invert face generally involve the length and number of the claw of the platypus. These are prone to change if wrong pigeonhole pressure is used in universe of dies for the coins. such variations are most frequently seen on coins produced at foreign mints. [ citation needed ] For the Broadley head obverse, to date there have been several variations : [ 3 ]
- 1999 with thicker lettering.
- 2000–2003 slightly reduced lettering by 0.01 mm.
- The 2004 issue had two forms:
- “the small head”: a head reduced all around by 2 mm, and thicker lettering. The version was in general circulation.
- “the large head”: an issue identical to the 2000–03 obverse. This version was only available in mint packs though, it is rarely found in circulation.
- 2005 non-commemorative and subsequent issues have reverted to “the large head” obverse.
- The 2005 WWII commemorative issue had an even larger head.
1981 Mintings [edit ]
In 1981, a big number of 20-cent coins were required, far more than the capacity of the Royal Australian Mint facility in Canberra, leading to some coins being minted at early facilities. The canadian depression of the 20-cent coin is known as the “ Ottawa Mint ” adaptation, which may be misleading as, post 1976, the Ottawa Mint only produced precious metallic element commemorative coins, like the Perth Mint, meaning the coins may have been produced at the Royal Canadian Mint ‘s [ 1 ] Winnipeg facilities.
due to differences in the mill and annealing process, the canadian assortment of the 1981 20-cent mint is classifiable to attentive collectors and flush cash handlers. The top and bottom edges of the mill is rounded over, not squared like the australian and London varieties, and despite being in circulation for well over 25 years, evening when well tire, the fields remain bright, and not dulled like those produced at other mints. These qualities are besides observed in canadian neologism of like ages. Some of the canadian coins were produced with a shortened first gear toe on the properly claw. These are referred to as the “ 3+1⁄2 claw ” variety .
Mintages [edit ]
The measure of 1981 and 1982 mintages of the 20-cent coin was sufficient to not require many coins released for circulation until 1990. The 1983 and 1984 coins were struck for circulation with mintages of 55.11 million and 27.82 million coins respectively, but were never released for general circulation. subsequently they were resmelted by the Royal Australian Mint, leaving the coins relatively rare. significant premiums have been paid for a belittled count of mint rolls from these years that have shown up in auctions. The Royal Australian Mint web site reports an issue of 2.7 million coins for 1985, but no 20c was minted for 1988. none were released in 1983-84 and there were no coins minted for circulation in 1986–1993 and 1995 ( Standard platypus design merely ) [ 1 ] [ 3 ] [ 4 ] [ 5 ]
