2012 International Year of Co-operatives PNC - Issue 4 A unique tribute to the International Year of Co-operatives (IYC), this is an official commemorative issue from Australia Post. Features a not-issued-for-circulation $1 coin from the Royal Australian Mint. About the International Year of Co-operatives: On 18 December 2009, the United Nations proclaimed 2012 as the International Year of Co-operatives. The co-operative business model is voluntary, democratic, independent, and self-sufficient, playing a major role in economic growth and social development. Since the 1850s, co-operatives have been part of Australia's socio-economic landscape, employing locals and redistributing profits back into local communities. The coin features building blocks, representing the stability co-operatives provide in a fast-paced global economy. Limited to 15,000 produced. Certificate numbers will vary.
