50 Pence - Charles III Monopoly

Issued under a licensing arrangement between the Royal Mint and Hasbro, this piece is legal tender in the technical sense but was produced entirely for the collector market. The Monopoly board game traces its commercial origins to 1935 in the UK, though the underlying game mechanics were developed by Elizabeth Magie in 1903 under her Landlord's Game patent — a fact Hasbro's predecessor Parker Brothers actively suppressed for decades to avoid paying royalties.
