A cancelled to order (also called and abbreviated CTO) postage stamp is a stamp the issuing postal service has cancelled (marked as used), but has not traveled through the post, but instead get handed back to a stamp collector or dealer.
Moschophoros...You make a good point..could very well be what happened.
One was not moistened, so did not adhere to the envelope leaving the original glue intact, but it was cancelled.
BlackJag...That is what I was leaning towards as a reason why it had full gum.
Now here is a couple of questions this brings to mind.1-
Is a used stamp only when it has gone through the postal system..?2-
Is a used stamp only when cancelled..Now the silly thing is after a stamp has been cancelled, accordingly to Canada Post
, a stamp can not be placed for service after it was previously cancelled..Against the law.
Very interesting stamp for sure.
