Editor’s Note: This is a first in a series of charts to be published in Mint Error News Magazine which were compiled by Bill Snyder of worlderrors.com. He undertook a study to painstakingly research and compile a list of known errors from major world countries. This chart covers Canadian striking errors from 1740 to 1997.

Bill states that “this study will determine which types of mis-strikes were common or rare, by country and time period. The study was limited to major striking errors such as double strikes, off-centers, brockages, etc.”
