Australia 2006 Proof Set
40th Anniversary of the Introduction of Decimal Currency
The only way you can get a 2006 silver 50c coin is via this set.
Australia has been producing proof year sets ever since decimal currency was introduced in 1966.
Proof coins are the same as those we see in our change, but are struck with specially prepared machinery on specially prepared blanks - the designs always stand out magnificently.
For the first time in 40 years, the 50c coin was not only round, but it was also produced using 80% pure silver.
This coin was only available in the proof set - the 2006 mint set includes a dodecahedron 50c coin struck in standard copper nickel.
The 2006 proof set was also the first to include 1c coins since 1991 - incredible when we consider they haven't been produced for circulation for close to two decades now.
The coins in this set are in perfect condition, as is the packaging.
