Australian 1966 Silver 50 cents – The round fifty cent coin was the highest-denomination and largest diameter coin of the Australian dollar‘s decimal coins, introduced in 1966. Due to large amounts made in 1966 and the rising cost of silver, it was not made in any other year. It was replaced by a dodecagonal 50 cent coin in 1969, which retained its reverse of the Australian Coat of Arms. It was made of 80% silver and 20% copper, but as the value of a free-floating silver price became higher, the coins’ bullion value became higher than their face value and so were withdrawn from circulation. A total of 36.45 million coins were minted with 14 million put into circulation.

I just signed up for this Artisan event/market in York WA.
If you are planning to be in the area (100 km east of Perth) and you like to meet me in person and see my work first hand then try to make it to this Arts & Crafts Fair. I will have a stall inside York Town Hall.
