50 Dollars H.S.B.C.

Bradbury Wilkinson printed the HSBC note series through this period using their characteristic intaglio work, and P#164 is among the more durable issues of the interwar Hong Kong dollar — a currency that had to navigate the colony's partial de-linkage from silver during the early 1930s as global silver prices collapsed. Hong Kong did not formally abandon the silver standard until 1935, meaning notes issued in this window were still nominally tied to a metal whose value was actively destroying the monetary systems of silver-dependent economies across Asia.

The New Malden plant handled security printing for numerous colonial issuers simultaneously, which occasionally introduced minor plate wear into later impressions of long-running series like this one.
