The rarest Australian coin minted for general circulation would be the 1930 Penny of which there were only 3,000 minted. It is currently esitmated that there are still about 1,500 of these still being traded in the market.
The rarest Australian Halfpenny is the 1916 (mule) coin, the 1923 coin is rare, and 1915, 1918 and 1939 (kangaroo reverse) coins are considered to be scarce.
If you refer to general circulation Australian Pennies rather than Proof coins, the order runs something like this - 1. 1930 Penny is the rarest 2. 1920 Penny with no dots on the reverse 3. 1925 Penny 4. 1946 Penny
The rarest Australian Halfpenny issued for general circulation would be the 1923 Halfpenny. It is thought that there were only 15,000 minted. One of these coins, even in poor condition, might fetch over $1,000 AUD. The rarest of all Australian Halfpennies is the 1916 "mule". It has the reverse of the Australian Halfpenny and the obverse of the Indian Quarter Anna coin struck on an Australian Halfpenny blank (or planchet). These are an error coin and should never have made it into circulation. It is thought that less 10 were struck and are worth tens of thousands of Dollars AUD. All known examples of this coin are accounted for.
The 1916-D is the rarest with a mintage of only 264,000 coins.
If you refer to the collector value of 1954 Australian coins, not much. Any value would be dependent on the condition of the coins.

An Australian Twenty cent coin weighs 11.31 grams, so there would be about 88 Twenty cent coins in a Kilogram.
There are no Australian general circulation decimal coins that could be considered to be rare. They have not been around long enough to become rare and, in every year they were minted, there were millions of each type minted. Even the oldest of the decimal coins are only just now reaching their maximum life expectancy of 40 to 50 years. Ask again in 50 to 100 years and there may be a few rarities.

The original Australian decimal coins were designed by Stuart Devlin and mostly produced by the Royal Australian Mint Canberra.
Australia puts famous or historically significant Australian identities or scenes on its banknotes, and distinctive or definitive Australian animals on the reverse of most coins to make the coins and banknotes identifiably and uniquely Australian. There does not seem to be much point to featuring US Presidents, Brazilian animals, Russian statues or Chinese emblems on Australian coins and banknotes, since it would all become very confusing.
