Unique Set of Canadian Quarters
Overstruck by 1978 Canadian Cent Dies
Certified by PCGS
SOLD
This is an amazing and unique set of Canadian quarter mint errors. Each of these are Canadian quarters struck by Canadian cent dies and are referred to as double denominations. These are among the rarest type of double denomination since they were deliberately overstruck by dies of a smaller denomination. Six out of the seven have dates that differ from the 1978 Canadian cent dies which makes them "dual date" mint errors as well. PCGS has authenticated and certified these as mint errors.
The Canadian quarter struck from 1968-1978 depicts the second portrait of Queen Elizabeth II on the obverse and the reverse portrays a caribou. These were struck in nickel composition with a weight of 5.05 grams and a diameter of 23.88 mm. In 1973, a different design was used for the reverse, portraying the Royal Canadian Mounted Police. It was a circulating commemorative coin. To my knowledge, this 1973 commemorative quarter overstruck by 1978 Canadian cent dies is unique.
Two of the seven quarters were overstruck off-center by the cent dies, the other five were struck within in the diameter of the quarter. PCGS noted on the inserts that two of the quarters were scratched and when this occurs, they are not given a numeric grade. In my professional opinion, having dealt in major mint errors for 45 years, it is more likely that the scratches are actually ejection marks or handling marks from the creation of these exotic and intentional major mint errors. These quarters (with a diameter of 23.88 mm) obviously did not fit properly in the collar designed for the 1978 Canadian cents.
Each of these are extremely dramatic and were obviously kept together as a set for half a century. These were intentionally struck and are prized and collected by many dealers and collectors who specialize in dramatic and rare major mint errors.
