50 Pence - Elizabeth II Algy Pug, Gold Proof

The Algy Pug coin is part of the Isle of Man Treasury's long-running commemorative pug series, which began in 1996 and has issued annual variants ever since — an unusually sustained run for a breed-specific numismatic programme. The Isle of Man has historically used its fiscal autonomy from the United Kingdom to pursue aggressively niche commemorative subjects that no sovereign mint operating under parliamentary scrutiny would sanction.

Struck at 22-carat in a 15.5g flan, this issue matches the half-sovereign weight standard — a deliberate choice that keeps the gold content commercially legible to bullion-aware buyers without formally entering the sovereign series.
