Tự Đức's reign was the longest of any Nguyễn emperor, but it unfolded almost entirely under the pressure of French military encroachment — the 1862 Treaty of Saigon ceded three southern provinces, and subsequent conventions stripped the court of meaningful fiscal independence. Gold issues of this type were never intended for commercial circulation; they functioned as court currency, used in ritual payments, imperial gifts, and mandarin salary disbursements at the highest ranks. Surviving examples almost invariably come from hoards or aristocratic family collections rather than any form of trade context.
The French takeover of the imperial treasury in 1885 scattered much of what remained.
