British West Africa's silver sixpence series was struck at both the Royal Mint in London and the Heaton Mint in Birmingham, with Heaton-struck pieces identifiable by an 'H' mintmark. The 1913–1919 window spans the whole of the First World War, during which metal supplies and mint capacity were under considerable strain — production was frequently diverted or curtailed to meet military coinage demands across the empire.
The .925 silver standard matched sterling, a deliberate policy choice to maintain exchange parity with British coinage circulating alongside it in the West African Currency Board's territory.
