50 Cents - Elizabeth II 2nd portrait, nickel

Canada's fifty-cent piece was effectively dead as a circulating coin long before this series ended. By the 1970s the denomination had vanished from everyday transactions — the Royal Canadian Mint continued striking them largely for sets, which is why so many survive in near-pristine condition while worn examples are genuinely hard to locate. The 1978 issue saw a subtle but documented reduction in rim width as part of a broader retooling of production dies.
