1 Crown - Elizabeth II Harry Potter and Portkey, Silver Proof

The Isle of Man Treasury built its reputation as a licensing pioneer for commemorative coinage, securing pop-culture franchises years before major mints took the practice seriously. This 2005 issue coincides with the peak of global Potter mania — the year both the Goblet of Fire film and the Half-Blood Prince novel were released — making it one of several IoM Crown types jostling for collector attention within a single calendar year.

KM# 1290 is one of the more obscure entries in the Potter Crown subseries, the Portkey scene drawing from Goblet of Fire specifically.
