Hong Kong's coinage authority shifted from the Royal Mint to domestic arrangements following the city's evolving pre-handover governance structure in the early 1990s. The Hong Kong Monetary Authority, established in 1993 through the merger of the Office of the Exchange Fund and the Commissioner of Banking, issued coins under its own name for only a brief window before the 1997 handover to the People's Republic of China rendered the issuing authority politically obsolete. Post-1997 issues continued the same coinage series under revised authority, making the HKMA-marked pieces confined to a five-year production span.
