Comment
Australia's first 12-sided 50-cent coin issued into circulation by the Royal Australian Mint (RAM) in 1969 replacing the 80% silver round 50-cent of 1966.No 50 cent coins were issued in 1967 and 1968.
* Diameter note: 12-sided (dodecagonal) shape - 31.5mm across flats, 32.5mm point to point.
For the variety "two parallel horizontal bars behind Emu's head" for the years 1979 and 1980, this is what you have to look for:
