The Bank of Korea was established in 1909 under Japanese colonial supervision, just months before Japan formally annexed Korea in 1910. This note was issued during that narrow window when the bank nominally operated under Korean authority — a distinction that collapsed almost immediately. After annexation, the Bank of Korea was reorganized as the Bank of Chōsen, and this series was absorbed into the new colonial monetary system without reissue.

Surviving examples are scarce. The short issuance window, combined with subsequent currency consolidation under Japanese administration, meant few notes remained in private hands.
