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.

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.

Why was the original Australian 50 cent coin changed?
The original Australian 1966 50 cent coin was made from 80% silver, and after the steep increases in the price of silver in the 1960's, the silver in the coin was worth more than the coin. It took only three 50 cent coins to make one ounce of silver. The coin was no longer cost effective to produce. The 1967 issue was halted and the coins melted down. The next, and all subsequent Australian 50 cent coins were dodecagonal and made from cupro-nickel. The change in shape was to make them more distinguishable from the slightly smaller 20 cent coin.
