In late August 2016 on the Australian Coin Forum a possible mule of a 2014 ANZAC $1 with a 10c obverse was reported. The images showed a distinct stepped rim around the entire obverse, very similar to the 2000 $1 mule, and the obverse was reported to be the same size as that of a 10c obverse die. The reported coin's specifications were given as 9g mass and 25.05mm diameter.
At the current time no other examples have been reported and no further tests have been carried out on the coin in question so the existence of the variety remains unconfirmed. The images certainly appear convincing and authentic, though the reported diameter is somewhat larger than is to be expected: a $1 coin should be exactly 25.00mm (RAM: One Dolar) however measuring 7 random circulated $1 coins produced mixed results– the narrowest diameter was 24.82mm while the largest diameter was 24.92mm – both short of the expected 25.00mm but certainly showing a lot of variability.
If the variety does turn out to be genuine it would hardly be surprising – a 10c piece has a diameter of 23.60mm – just 1.4mm short of the $1 and an easy difference to miss at a glance. Given that such a die mix-up already occurred in 2000 a reoccurrence would hardly seem unlikely. Whatever the outcome, it certainly pays to check your change.
