The 2009 1oz Silver Australian Lunar Series II 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.
