1 Gunayh - Abd al-Azīz

The Saudi gold Guinea — modeled dimensionally on the British sovereign — was introduced in 1951 as part of Abd al-Aziz ibn Saud's effort to establish a credible gold-backed currency at a moment when oil revenues were beginning to transform the kingdom's finances. The Philadelphia Mint struck these pieces under contract, an arrangement that suited a country without its own minting infrastructure.

Mintage was relatively brief; by 1954 the Saudi Arabian Monetary Agency had shifted priorities toward paper currency backed by silver riyals. Philadelphia's involvement makes this one of the more unusual contractual relationships in mid-century American mint history.
