Tagging Error Identification Site.

I brought this old thread back to life as I have just found a new variety I have never seen before. Want to show it for information and if anyone knows anything about this type. It is on Canada #857-858 in plate blocks affixed to a Canada Post official FDC. See photos attached. It has the normal G2 side tagging at edges, but there is also a large wide band between them. Similar to but different again from the tag# T4 type g2e that Robin shows on his site. Its like a steam roller drove between the lines. What a name- steam roller, or better roller tag.

Addendum: after looking at Robins site again I see now that this is the one he has listed. I think. Just did not note that he stated there was also traces of tag between the bars. There appears to be a bit more than a trace between the bars on the ones shown. Also looked at #858 and it appears more like tag 2 type g2 shown on that one which has more than a trace and a different value? I wonder what value should be applied to these covers?

I checked the whole Adminware site...Why don't you send it to him to see what he thinks.

Robert, I just added an addendum to the post. Robin uses SCF and no doubt may chime in on this item. And I was surprised to find it. You just never know what you have until you turn the lights out. By the way, have you noticed that the so called stable tagging used over the last several years is beginning to show signs of migration. I had my covers stored in an archival storage box in the dark in fairly steady humidity and temperature. Now when I put the UV to the back of the cover touching the stamp on the other, signs of tagging lines are beginning to show on the cover backs.

Yes No1philatelist...Good flyspecking.
Seems all the good flyspeckers come from Nova Scotia.
I was born in Halifax..haha
