1 Sovereign - Elizabeth II Lest we forget, Gold Proof

Gibraltar's sovereign issues occupy an odd corner of numismatics — the territory has no independent monetary authority, yet has issued collector coinage under royal warrant since the 1970s, largely through the Pobjoy Mint and later the Tower Mint. The "Lest We Forget" series tied to World War I centenary commemorations ran across multiple years and issuers, this 2016 piece marking the centenary of the Somme — a battle that killed or wounded over one million men between July and November of that year.

The .917 gold specification matches the traditional sovereign standard established by the Great Recoinage of 1816.
