1 Dollar The Wedding of Prince Edward

Prince Edward's 1999 marriage to Sophie Rhys-Jones generated an unusually large wave of Commonwealth commemorative issues, with several smaller nations producing crown-sized copper-nickel pieces aimed squarely at the collector gift market rather than circulation. Sierra Leone was in the grip of a brutal civil war that year — the RUF's campaign had devastated the country's infrastructure — making this coin a product of a government-in-exile arrangement rather than any functioning domestic mint operation.
