Technically they are used with a postal authority marking, however I think most collectors would only keep them until a better cancellation comes along.
Having said that, some folks do not mind a pen/sharpie cancel, but in fairness I would point that out before a trade.
thank you for the reply
i will start removing the pen-cancelled stamps from my doubles and place them aside with the exception for rare stamps
i wish canada post would not do that to stamps
Pen cancels are the worst. Magic marker or Sharpie cancels go in the trash usually. Why are they always on the nicest stamps?
I have just one criterion for adding a used stamp to my collection, assuming I can afford it. I have to like the appearance of the stamp. If a cancellation of any type detracts from the appearance of a stamp, I do not buy it. If I find a stamp in my collection that has a disfiguring cancellation, I usually get rid of it, either by throwing it in the recycling bin or adding it to a lot into a for a club auction. as far as I’m concerned, one ugly stamp on an album page ruins the whole page. I’d rather have a blank space than one filled with philatelic garbage.

I consider such stamps as non-collectible except those for which pen cancels were usually used.
If pen-cancelled stamps are otherwise in good condition, I keep them as space fillers. In some places it may have become the normal condition of used stamps anyway. Also consider that there may be some "flyspeck variety" which you and I don't know about, but some specialist might be interested in no matter what the cancellation.

I like the old (1800s) pen cancels written by someone with excellent penmanship.
This is the only pen-cancelled stamp in my collection, and, of course, it's not a commemorative like Kiera was inquiring about. The cancellation doesn't bother me, and according to my old (1996) Scott U.S. specialized it, a pen cancellation confers a value of $25 on it (assuming I have correctly identified the stamp, as U.S. 10). Then there's the plate crack, which Scott tells me is worth $60.


Here's the kicker, which is driving me nuts. This image was scanned from a cover which I received in a trade, and I CAN'T FIND THE DAMNED COVER! Scott values the stamp on cover at $90. So, potentially, that cover is worth a fair amount of money. I doubt I would ever have parted with it, but there have been times when I made a few trades because I didn't have enough cash for something I wanted even more. If/when I find it, I'll show you the whole thing.

of course, you say 10, but you write it up as 11....
I'll see your 11 and raise you to 12

I always save those and send larges bunches to Stamps for the wounded.

Good uses for what is otherwise philatelic "garbage".

i am preparing a bunch of recent commemorative canada stamps to trade as mentioned in the temporary post here and i have a few of these stamps where the post office has used a pen to strike the stamp
do collectors throw away stamps marked with pen - and sometimes markers - in the recycle bin or are they still exchangeable?
what is the consensus on there marked stamps?
thank you for your replies
