Canada Airmail Stamps. Question On Perforations

Pictures of a couple of mint blocks that are part of my collection.

The first one has me thinking that the perforation guy was drinking that morning and missed the target a bit.

The second has perforations that appear out of place.

My question is.... does this add to or subtract from the value of the stamps?

Thank you for your responses.

The first block is indeed not centered very well and the value may be seen as less. The second is a booklet pane. Looks just fine to me.

Neophyte, what do you mean by "perforations appear out of place" ?

My lack of knowledge is showing...again...still
I had it it my head that perforations should "miss" each other where they cross.

Once I read rogdcam's response I started looking more closely at stamp blocks from that period and sure enough some do and some don't line up nicely where they cross each other.

So now I am looking at stamp blocks from the Scott # 500's and on and the perfs seem to line up much better on the crossing points

They musta fired the guy who was drinking sometime in the 60's ... or the perforation system vastly improved, I suspect the latter to be true.

Either way it just proves just how much I have to learn.

Thx and have a great day

Are you referring to the way the perforations do not meet neatly where the horizontal and vertical lines meet? As a newbie, are you familiar with the terms "line perforation" and "comb perforation"? If not, suggest you check them out.

On the first block, though it is hard to tell because of the blurry picture, it almost looks as if the horizontal perforator struck twice, not quite at the same angle.

Perforation technologies like 'electric eye' greatly improved the centering on stamps around 1940 on-ward.

Hi Neophyte. Thanks for clarifying. Just so you realize, there are two distinct types of perforation used namely line perforation and comb perforation.

Thank you everyone

The link to perforation types was just perfect.

Cheers!
