1 Crown - Elizabeth II Harry Potter and Portkey

Issued under the Isle of Man's long-running licensing arrangement with Warner Bros., this crown appeared during the peak of the franchise's commercial dominance — Goblet of Fire hit cinemas the same year. The Isle of Man has operated as one of the most prolific producers of licensed pop-culture coinage since the 1980s, a revenue strategy that makes its commemorative output vast and, for serious collectors, largely uncharted territory.
