This is a raffle for a 10 oz uncirculated 2011 Australian Kookaburra silver coin. Australia first issued a one ounce silver bullion coin in 1990. It followed the series of Australian native fauna, which began with the platinum Koala in 1988, and the gold nugget coins changing to a kangaroo design in 1989. When introduced in 1990, the 300,000 issue limit of the Kookaburras was oversubscribed by more than five times, and supplies ran out on the first day of issue. The Kookaburra is the only major silver bullion coin which changes its exact design every year, making it also more attractive to collectors, although the kookaburra theme remains the same. In 1992, the Perth Mint introduced large silver bullion coins, in weights of two ounce, ten ounces and one kilogramme (32.15 ounces). Initially these were produced as proofs or specimens only, but are now available in a non-proof version. Originally the large silver coins retained the same design each year, but now they too have a different kookaburra design each year.
