50 Pence - Charles III Jurassic Britain - Loricatosaurus, Silver proof

Loricatosaurus pricus was excavated from the Oxford Clay Formation in Oxfordshire, a Jurassic marine deposit that has yielded some of Britain's most significant dinosaur material since the 19th century. The Isle of Man Treasury has built an aggressive commemorative program around such themes, issuing themed wildlife and palaeontology series partly to distinguish its coinage from Royal Mint output. This particular strike in .925 silver is the proof variant of a base-metal circulation issue, a familiar structure for the series.

The Oxford Clay sites where Loricatosaurus material was found were largely exposed during Victorian-era brick quarrying operations near Peterborough.
