Going through some plate blocks....that I dont really collect, I found this one of Scott 174. There is a note in Unitrade that mentionnes "An additional columnof perforations is occasionally found in the vertical margin of the 12c, 20c and 50c values". This is exactly the case here. I wish they would be more precise than "occasionally" ! I wonder how rare it really is ???

I hadn't noticed the Unitrade note before and was unaware of this variety.
Thanks for bringing it to our attention.
Sorry I don't have any knowledge on the frequency of this happening.
None of my blocks have this extra column.

It was due to the Arch/Leaf flat plate printed stamps of the set not having straight edges like the issued flat plate sets before it did like in the Scroll set, etc. The rotary press stamps (from the same set and others) never had straight edges since it was perforated on a different kind of perforator. However, what happened is that one of special perforating extra wheel setting combinations that was used for some of the smaller size lower denominated stamps was left on the perforator and not removed for the larger size stamp resulting in the extra perforations. Thus, the extra perforating wheel(s) that was left on one side or the other from the smaller size stamps resulted in this.

Hi Coriandre,

My UL Plate PB#1 of this issue also has a double margin.

You can also see a extra perforation in the top left corner with the first two verticals lines (from the left) and then a single perforation.

I looked on eBay and saw a few more with the same perforation in the selvage. It seems quite common. Still a fun variety to discover !

It appears that Canada Scott 174 plate block may be the easiest to find with this variety so far.

Then, it may be Canada Scott 176 plate block as is shown below but it is harder to find.

The hardest to find so far may be Scott Canada 175 plate block with this variety.

Has anyone seen any Canada Scott 175 plate block with extra vertical perforations?

Checked many Canada Scott 175 plate blocks and have found none with this.

Also, checked many Canada Scott 203 plate blocks and found none with this.
