Great Britain
William IV Proof Shilling 1831 PR65 NGC, KM713, S-3835. Plain edge. A spectacular representative from William IV's coronation Proof set. Arguably deserving of a plus designation for its arresting toning pattern, that weaves electric blue and amethyst around the artfully maintained devices.
