PSE News

With an increase in the number of graded stamps of Canada, PSE has reviewed and updated its Stamp Market Quarterly values.  With this review, it became apparent that many stamps were initially undervalued.  Of note, high grades seem to be a bit more common in the mid to late 20th century, most likely, due to the improved perforating techniques that came along during this period.  In contrast, higher grades in the Jubilee issue seem particularly difficult due to relatively poor centering. The Jubilee issue, for this reason, should rival the popularity of the US Colombian issue.  The more modern Queen Elizabeth period, however, has not seen as much interest.  As the interest in, and quantity of, graded Canadian stamps increases be on the lookout for the issues of Canada to start appearing in the PSE Set Registry soon.
