正面描述 The fourth portrait effigy of Queen Elizabeth II, designed by Susanna Blunt, is depicted in right-facing profile bust, wearing a diamond diadem and pearl drop earrings, with a pearl necklace visible at the base of the neck. The effigy is set against a finely engraved radial line background that extends across the entire field, a security feature introduced on the Gold Maple Leaf series. The legend ELIZABETH II arcs along the upper periphery, while the denomination 50 DOLLARS and the date appear along the lower periphery. The designer's initials SB are incused below the Queen's truncation. The overall portrait is rendered in high relief with crisp, detailed modeling.

附加信息

Canada's Gold Maple Leaf gained its security leaf and radial line background in 2013 and 2015 respectively, direct responses to a sophisticated counterfeiting problem that had embarrassed the Royal Canadian Mint. The laser-etched maple leaf micro-feature, visible only under magnification, was developed in partnership with the Canadian Bank Note Company — an unusual collaboration between a coin producer and a currency printer. The .9999 fineness itself, introduced in 1982, was a deliberate one-upmanship over the South African Krugerrand's .9167 standard, a commercial calculation that paid off handsomely in export markets.
