Australian $1 Coins

2000 Mule

In 2000 the Royal Australian Mint released into circulation the standard design $1 coin. Most of these were released in Perth, Western Australia. In 2002 it was noticed that the obverse on some of these coins was different. Closer examination showed that the obverse was 1.9mm smaller than the usual design, more examinations then found that it was actually the 10c obverse. It seems that during manufacture a 10c obverse die was used by mistake and some escaped detection before leaving the mint.
As yet there is no accurate figure on the number in existence, the two people that have found and researched most of the mules disagree slightly on an estimate of actual numbers in existence, one places it around 6,000 with about 1/3 found, the other places it down in the 2,000 range.

A comparison between the mule obverse and the normal obverse, notice the "double rim" formed by the smaller die with the obverse also being noticably smaller when compared to "normal" coins.



Most of these coins have been found in Perth but some have traveled as far as Cairns, quite a few have been found in Victoria, some in Sydney but none have been reported from the Northern Territory, South Australia and Tasmania with most being found in Very Fine condition, however, the best known example of this coin was only found in early 2005, giving hope to all those searching that there are more to be found.
The Mint has been maintaining a stony silence about these coins and are not as yet officially recognizing these coins existence.
What is known for sure is the number of avid collectors eagerly searching through large volumes of $1 coins to find them with varying degrees of success will continue on their quest for that elusive mule.
