It was previously reported that the 3c, 5c and 10c Beneficial Insects were reprinted around December 2009, with the thinner black border.

I just noticed that there is a constant variety on the second stamp in the sheets of 50, it consists of a vertical brown line running from the margin to the right of the inscription, down into the stamp, just past the C of Canada.


It is present on all three reprint sheets I have, and
not present on the original printing.
Can anyone else confirm this variety?
