50 Yuan Panda

China's Panda gold series dropped its fixed-weight standard in 1982 and has issued annually since, but 2001 marked one of the last years before the series underwent a significant packaging and marketing overhaul by the People's Bank of China. Mintage figures for this date were never officially published with full transparency, which is characteristic of the series broadly — a deliberate policy that has historically sustained collector demand by keeping supply ambiguous.
