1 Crown - Elizabeth II Blue British Short Hair Cat, Silver Issue

The Isle of Man's annual cat crown series, running continuously since 1988, became one of the most aggressively collected modern series of the 1990s — a phenomenon driven largely by the Franklin Mint and Bradford Exchange secondary market, which inflated perceived scarcity and pushed collectors to chase each annual variety. The British Shorthair issue appeared near the peak of that speculative bubble. Most examples were immediately slabbed and shelved, which is precisely why so many survive in pristine condition today.

KM#966a denotes the silver proof variant within a release matrix that also included base-metal and gold options — the Isle of Man Treasury routinely issuing the same design across multiple compositions simultaneously.
