50 Yuan Panda

China's Panda gold series, launched in 1982, made a deliberate break from most major bullion programs by changing the reverse design annually — a policy that transformed the series from a straightforward bullion product into an actively collected annual issue. The decision created substantial secondary-market premiums on individual dates, particularly low-mintage years.

The 2007 issue was produced the same year China overtook South Africa as the world's leading gold producer, a shift that ended over a century of South African dominance.
