The Australian one kilo silver piece (abbreviated as 1 kg and designated with Ag for "silver") is a bullion coin format. Uniquely, in Australia there are two mints authorised to strike legal tender: the Royal Australian Mint (which also makes the country's circulating coinage) and the Perth Mint which only makes collector and bullion coins, as well as other bullion products.
Both mints endeavour to create coins with attractive designs, and to introduce new designs and themes often, in order to raise the numismatic value of the coins over the value of previous metal used.
This commemorative silver one kilo (1 kg) coin denominated as $30 celebrates the Centenary (100th anniversary) of Qantas.
Qantas Airways Limited is the flag carrier of Australia, and is the third-oldest airline in the world after KLM and Avianca. The company was founded in November 1920; it began international passenger flights in May 1935. The Qantas name comes from "QANTAS", an acronym for its original name, Queensland and Northern Territory Aerial Services, as it originally served Queensland and the Northern Territory only. It is nicknamed "The Flying Kangaroo".
The coins are in Proof FDC grade and were released boxed. They are plated with 99.99% gold. |
