50 Yuan Panda

China's Panda silver series, running continuously since 1983 with one interruption in 2001, shifted to metric weight standards in 2016 — abandoning the troy ounce denominations that had defined the series for three decades. This 150-gram piece sits at the top of the standard annual bullion lineup, issued in strictly controlled quantities alongside the smaller 30-gram, 8-gram, and 3-gram coins. The People's Bank sets annual mintages without advance disclosure, a deliberate policy that sustains secondary market tension.
