10 Dollars - Elizabeth II Year of the Snake

Pobjoy Mint, operating out of Surrey, has produced bimetallic titanium-and-silver issues for various client territories since the late 1990s, and the technical challenges remain non-trivial — titanium cannot be struck with the same die pressures used for silver, requiring separate tooling and careful assembly of the two components before final striking. The Chinese lunar series issued through Pobjoy for territories like the Isle of Man and others became a reliable annual franchise, though collector fatigue and proliferating competing issues from larger mints gradually eroded their secondary market premiums through the 2010s.

The titanium centre on these pieces characteristically develops a subtle iridescent tone over time, a natural oxidation effect specific to the metal.
