2 Dollars - Elizabeth II 4th Portrait - Year of the Pig - Silver Bullion Coin

The 2007 Year of the Pig completed Perth Mint's first full twelve-year Lunar Series I cycle, which had begun with the 1996 Year of the Rat. Closing out a series carries its own collector logic — demand for the final release typically spikes among those completing sets, and Perth recognized this, producing the Pig in multiple weights and finishes simultaneously.

The two-troy-ounce denomination is a Perth convention rather than a legal tender reality; the face value is nominal, with Australia's legal tender framework under the Currency Act simply accommodating commemorative issues of this kind.
