Unitrace 236 1 Cent Double Coil Join Strip

Any thoughts about this coil join strip of 7 of the 1 cent war issue perf 8 would be most welcome as I have never seen anything like this before.





The central five stamps are slightly mis-cut with the top and bottom not parallel to the coil edges. The stamp at each end is joined to these using a strip of brownish paper. Both the single and strip have torn perforations - not cut. The singles and strip are butt joined not overlapped. The gap where the join is these is slightly wider thab the normal separation and a new perforation has be created down the centre. These new perforations in the joining strip seem very slightly smaller than the original ones betwen the five central stamps..




As I said I do not understand this. I do not think it is a philatelic creation as it seems a very elaborate item to make for what would be mot much gain.

If there are any others around I would be very pleased to hear about them

It's a nice unique piece.

Normally, this would only occur at the beginning or end of the roll (connecting tabs to the roll at both ends).

This looks like a case where there was a break in the coil and a repair job was made so that a complete roll could be completed (adding the needed amount in the middle).

Never seen one either and it was a small insert. The fact that stamps were added (as opposed to just re-attaching two coil ends) is indeed interesting.

A nice showpiece regarding the coil production of the day in my opinion. I'm not a coil expert of that era but that is my best guess.

Keeps the count correct as coils are sold by roll with set number of images.

Check the link I supplied for another example.

ParcelpostguyThank you for the link. I do not often stray into QE 2 territory these days and had not seen that before.

I now realise that I had assumed that before Canadian coil stamps were printed in rolls of 500 the 100 stamp sections from the sheet printing were joined using part of the margin from one side of one of the strips. This was the technique used for GB stamps. Looking on ebay it seems that they were made using the joining strip method as above. Please correct me if I am wrong.

Again thinking a bit more about the strip I showed I wonder if somewhere in the perforation process something went wrong and 5 stamp were damaged beyond use. To keep the number of stamps in the final roll correct another 5 stamps would have to have been added. To do that there must have been some spares available. Again I assume that these came from a roll or part of a roll that had been badly damaged or miss cut etc. Perhaps the workers selected 5 stamps from such a roll that were just about acceptable and used them for the repair.

If a longer section was damaged then, with the joins being further apart, it would not have been so obvious what had happened and this variety would have been missed.

I have also just realised that the existence of coil join pairs would have relied on someone buying a coil and then unrolling it to find the joins.

Were the machines the coils were dispensed from coin operated so they could be used by the general public. I would have thought so, but were there also machines for office use that could be preloaded using a coil of 500 that had been purchased from the post office and then used by the office workers as required. This would explain the precancelled coils.

Lots more to think about - time to cut the lawn before I get a headache.

Time to stop thinking and cut the lawn!!!!

It could be from a coil repair in which a coil roll of 500 stamps was being rolled/wound up and it split and broke off during this production step so that it was reattached and fixed. Also, it could be as an economic measure whereby a coil strip that broke off was put aside and salvaged during production and was attached together to another roll in order for it to be completed with 500 stamps in it. The perforated strips used have a slightly different gauge than the coil stamps themselves. It is most apparent with the gauge 9.5 perforated coils from 1948 to 1967 where the perforated blank strips gauge 8.

In US coil paste ups, fakes can be found.

EDIT: I am NOT implying that the strip shown above is a fake. I mention US fakes only since the thread is listing various possibilities in coil paste ups.

Just to be clear, the repair was made before the sheets were stripped into individual coils.




I was aware "different pictures were printed on paper" but the coil production process, print picture on paper, slit into strips and roll up; oops repair needed, remained the same.

As to the detailed production of GB or Canada coils and when paste ups were or were not made, I will leave to others. Once the USA went to rotary presses making coils did not require paste ups as a normal process; splices between rolls of paper and splicing repair, yes.

From 1912 to 1929, Canada coil stamps had regular paste-ups since they were made from separate printed sheets.
From 1930 onwards, Canada coil stamps were made from printed paper web rolls. (It's Scott 263 shown by OP.)

Now I (and others) know, jogil, thank you for that.
