5 Pounds - Elizabeth II Three Graces

Tristan da Cunha, a British Overseas Territory in the South Atlantic with a permanent population under 300, issues coins primarily for the collector market — they see no meaningful circulation. This 2018 piece is struck in Jasperware, the distinctive unglazed stoneware developed by Josiah Wedgwood in the 1770s, most famously produced in pale blue with white relief figures. Using ceramic as a coin substrate is a deliberate nod to that material's association with the Three Graces motif, which Wedgwood reproduced extensively.

PCGS certification of ceramic pieces involves separate handling protocols from metal coins, as the substrate is brittle and vulnerable to edge chipping during encapsulation.
