All coins have length, width and depth, and are thus 3D objects. The Australian 50 cent coin has twelve sides, and so is dodecagonal in shape.
No. Australian coins, with the exception of the 50 cent coin which is 12 sided or dodecagonal, come in the regulation shape of "round".
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.

Yes. The 50 cent coin is commonly used in Australia. As of 2016, there is no plan to remove the 50 cent piece from circulation.
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.
The volume of the dodecagonal Australian 50 cent coin is about 2,338 cubic mm.
Such a coin does not exist. There were no Australian 1967 50 cent coins minted.
Prior to 1948 the image of Lady Liberty was on the 50 cent coin. From 1948 to 1963 Benjamin Franklin's image was on the 50 cent coin. From 1964 to present John F. Kennedy's image is on the 50 cent coin.
