Canada’s Partially Imperforate Stamps

Among the many varieties found in Canadian stamp collections is a group of odd stamps that are imperforate on one side only. There are so few of these that it is no surprise collectors place great value on them when bidding at auction. In this commentary, we provide a number of the examples we have recorded over the years.

How these partly imperf errors occur is not obvious, but many of them are far rarer than the fully imperforate pairs offered in most auctions. What started off as one or two a few decades ago is becoming far more frequent as errors are made at the printers. The examples we show above are not a complete listing. The catalogue values shown are those in effect at the time the stamps were sold.
