Other than the initial Australian 1966 50 cent coin which was round, all subsequent Australian 50 cent coins from 1969 have been dodecagonal or 12 sided.
Because they are of a similar size to the 20 cent coin, they were made 12 sided so that vision impaired people could feel the difference.

Can you shape an Australian coin?
No. Australian coins, with the exception of the 50 cent coin which is 12 sided or dodecagonal, come in the regulation shape of "round".

Such a coin does not exist. There were no Australian 1967 50 cent coins minted.
Why was the metallic composition and shape of the 1966 Australian 50 cent coin changed?
The Australian 1966 50 cent coin was the first and last round Australian 50 cent coin produced by the Royal Australian Mint. With the wisdom of hindsight, this coin was a bit of a blunder on the part of the Royal Australian Mint. It was only very slightly larger in size to the Australian 20 cent coin and it had an 80% silver content at a time when the price of silver was increasing rapidly. It took only three of these coins to get one ounce of silver.

Why isn't the Australian 50 cent coin round anymore?
The round Australian 50 cent coin was only ever issued once, in 1966. Three of these 50 cent coins contained one ounce of silver and, as the price of silver increased, the silver content was worth much more than the face value of the coin. The round 50 cent coin at 31.5 mm was also considered to be too similar in size to the 20 cent coin at 28.52 mm. The replacement 12 sided (dodecahedronal) 50 cent coin first issued in 1969 is still 31.5 mm, but its distinctive shape makes it stand out in appearance and feel from other Australian coins.
What does an Australian 50 cent coin look like?
