From 1965 to 1989, Canadian one cent coins featured the effigy of Queen Elizabeth II, designed by Arnold Machin. The reverse design remained consistent with the iconic maple leaf, symbolizing Canadian identity.
In 1982, a major change occurred when the composition shifted from bronze to a copper-plated steel to address metal shortages. This transition, alongside minor design adjustments, marked significant changes in the coin's production.
Collectors often seek these coins for their historical and material transitions, with certain years and mint marks being particularly prized. The period from 1965 to 1989 is notable for its blend of tradition and innovation in Canadian numismatics.
