The 2009 1oz Silver Australian Lunar Series I bullion coin celebrates the Year of the Ox and was struck by The Perth Mint in 999 fine silver. It forms part of the Australian Lunar programme, pairing a changing Chinese zodiac reverse with Australian legal tender status and strong collector appeal among silver stackers. It also sits in a period of stronger modern bullion demand, which can support a slightly higher collector premium than a plain low-premium silver coin.
