50 Pence - Charles III Lunar south pole, Silver

The British Antarctic Territory, though a real UK Overseas Territory administered from the Foreign Commonwealth & Development Office, has never had a civilian population requiring circulating currency. Its coins are legal tender in name only, issued exclusively for the collector market under Crown authority. This lunar south pole piece reflects sustained international interest following NASA's Artemis program and ISRO's Chandrayaan-3 mission, which successfully landed near the lunar south pole in August 2023 — the first spacecraft to do so.
