The 1942-48 War Effort Issue Part Two
Today's post will explore two more complex aspects of this much under-rated issue: the booklets & booklet panes, and the coil stamps. Coil Stamps This is the only issue of Canada to have coil stamps in two different perforations: 8.5 and 9.5 vertically. The original issue that appeared between 1942 and 1943, was perforated 8.5, and was generally printed on softer paper. Later in 1948, the coils were reprinted on a thicker, stiffer paper and were perforated 9.5 instead of the 8.5. The difference is marked enough that with experience, you will be able to distinguish them from one another without having to measure the perforations. The scan above shows the two different perforations, with 8.5 on the left, and 9.5 on the right. As you can see, this difference of one hole, makes a large difference to the appearance of the stamps. In general, the perf. 8.5 coils tend to have holes that are often not fully punched, and are widely spaced, giving perforations that are much wide
