Shadow Perfs On A Nova Scotia Stamp 8

Is this unusual? To the left and right of the perfs are mirror indentations of the perfs. These indentations do not extend onto the face of the stamp. They only appear on the reverse. I ran the images thru retroreveal in an attempt to provide the most useful image possible.

Hi gettinold

Nova Scotia stamps are notorious for these blind perfs...They are not rare but not super common..I have a few like the one below.

I was curious about the indentations to the right and left of the perfs which appear to mirror the actual perfs. Would those indentations be considered blind perfs? They do not break the paper and aren't visible on the face of the stamp. Part of me wants to soak a few of them to see if the indentations are restricted to just the gum.

Blind perfs can be caused by a number of reasons''

1 - Pins could be clogged up.
2 - It could have been the bottom of 2 sheets put through at once.
3 - Worn perforation pins.
4 - Paper thickness with wrongly aligned perf pins.
5 - Etc.

The images in my OP weren't very clear. I didn't use a black background to show the normal perfs were complete. My apologies for this error. I have better images which I hope can make my question easier to understand. Simply put, the reverse side of the stamps have rows of indentations which run alongside the normal perfs. On the images below you will see them running vertically and horizontally alongside the actual perfs. Blind perfs (as I understand them) will break the paper and will be visible on the front of the stamp. The stamps below have normal perfs and this oddity on the reverse which consists of wannabe perfs which run alongside them.







I used the retroreveal tool on one of the cropped images. I think it helps show the indentations clearly. Trying to figure out how multiple rows of perfs could appear on a stamp

Wouldn't the stamps have to be run thru a perf machine more than once?

I also have what I call roller marks on Scott...
8-9-11a-12-13, etc.

Not a rare oddity..But cool

Roller marks? I haven't seen these before. Thanks for all your help. In retroreveal they sort of look like tread marks left by a tractor or a tank.

Hey guys. I think you may want to consider other factors.

I see what I believe was adhesion of ink and paper of other stamps on the gum of those shown. No doubt they were incorrectly stored. A pile of sheets stacked with a fair amount of pressure from weight on top, then add time and some occassional heat and humidity and voila, you have what looks like a second set of perforations. So it is entirley plausable it may be mostly gum squeezed and filling into perf voids and giving the appearance of blind perfs. Especially when they are not seen on the front of the stamp.

If not mistaken, I read somewhere the last of those N.S. remainders were stored for a long time before being sold.

I read that the majority of these stamps were stored in England and Nova Scotia. Humidity, according to the article I read, is a problem in these areas. I also saw the impression of the front of the stamp on the reverse. Akin to offset...kinda. I thought either these stamps were piled on top of one another after printing or improper storage and humidity had their way with the stamps. The interesting feature however continues to be the tracks that seem to connect the indentations with the actual perfs. I can't account for that. These tracks are visible in the Retroreveal images.
