10 Yuan Panda

China's Panda gold series abandoned its fixed-weight system in 2016, switching from troy ounces to metric weights — a deliberate alignment with international bullion standards that also conveniently rendered the entire pre-2016 series incompatible with the new sizing. The 1g piece sits at the smallest end of the annual Panda lineup, sharing its issue year with five other sizes struck simultaneously at the Beijing, Shanghai, and Shenzhen mints.

Designs change annually by statutory requirement, a policy in place since 1982 with the sole exception of 1987–1988.
