1 Dollar Golden Wedding

Issued to mark the golden wedding anniversary of Queen Elizabeth II and Prince Philip in 1997, this piece belongs to a wave of commemorative coinage produced by Commonwealth-adjacent and non-Commonwealth nations alike, many with no constitutional link to the British crown whatsoever. Sierra Leone had been a republic since 1971 and had no obligation — ceremonial or political — to issue such a piece. The motivation was almost certainly commercial: the late 1990s market for British royal commemoratives among collectors in the UK and North America was substantial enough to make licensed issues from distant mints genuinely profitable.
