10 000 Yuan Year of the Dog, Scalloped

China's annual lunar gold bullion program has issued kilogram pieces since the 1980s, but the scalloped edge on this format was introduced to distinguish the premium collector tier from the round issues struck in the same year. The 2018 Dog year kilogram is one of the heaviest and largest pieces routinely produced within the series, with the People's Bank of China tightly controlling authorized mintages through a small number of licensed distributors.

Scalloped edges on coins of this mass present genuine technical difficulty at the die stage — maintaining clean lobe definition across a 100mm planchet requires precise pressure tolerances.
