500 Yuan Yandi, Semi-mythical First Emperor

The Yandi and Huangdi (Yellow Emperor) series, launched by the People's Bank of China in the early 1990s, drew on founding mythological figures whose historical existence remains genuinely contested among Chinese scholars. Yandi — the Flame Emperor — is traditionally credited with teaching agriculture and herbal medicine to early Chinese civilization, placing his supposed reign somewhere around 2700 BCE. The PBC issued these large-format gold pieces partly in response to surging collector demand from overseas Chinese communities, particularly in Taiwan, Hong Kong, and Southeast Asia, where ancestral identity carries commercial weight.

At five troy ounces, this is among the heaviest single pieces in the series.
