10 Fen Pattern, 2nd series, nickel, with Jin

By 1936, the Nationalist government under Chiang Kai-shek was pushing hard to standardize China's chaotic coinage system, and the Central Mint in Shanghai produced multiple competing pattern submissions for the proposed second-series decimal coinage. The "with Jin" designation refers to the inclusion of the character 鎳 (jin, meaning nickel) on the coin, an explicit compositional declaration that appeared on some pattern variants but not others — a detail that generated genuine debate among mint officials about whether labeling metal content was necessary or redundant given the planned public education campaigns.

The full second-series program was effectively killed by the outbreak of full-scale war with Japan in 1937. These patterns never reached circulation.
