The number of U.S. off center cents, nickels, dimes and quarters is mind boggling compared to the number of Canadian off centers that are out there. I've personally seen several $50.00 bags of off center cents and the number in my collection is extensive. Same goes for Cuds and other error types. I know a person that has over 20,000 U.S. Cuds in his collection and I have owned hundreds at a time myself but only have 2 on Canadian coinage. It has to be a quality control issue.
