2000 Yuan Year of the Pig

China's lunar gold series has been running since 1981, making the 2007 Year of the Pig the completion of the second full twelve-year cycle. The 155.55g weight corresponds to exactly five troy ounces — a format the People's Bank of China introduced to target institutional and high-net-worth collectors rather than the retail bullion market.

Mintages on the five-ounce lunar issues from this period were tightly controlled, typically in the low hundreds.
