Scott 711-Xx Precancel

I was thinking about this precancel..I looked in Unitrade and it shows only ONE precancel associated with this stamp and ""The Standard Canada Precancel Catalogue"" also indicates only ONE precancel.

I have been looking at this stamp for about a week..FIG.1 stamp on the left is the one I have had in my book..BUT, I came across another Scott 711-xx that seemed to have a THICKER precancel bars as compared to the regular one.

FIG.2 shows a closeup of the bars on both stamps and they look to be a obvious different sizes.

FIG.3 show the UOM (Unit Of Measurement)..BTW, this measurement is only used to indicate differences of objects like percentages, and when doing this we need not have to use certain rulers...It indicates the NEW precancel on the right has bars that are 11.96% bigger/wider than the standard Scott 711-xx stamp.

WHAT DO YOU GUYS THINK..???

Robert, could it be a different printing with a different mat used?


Peter

I thought about that to Peter..The first printing is from the 1977 printing which is classified as 12.0x12.5 which the new stamp s as shown below..The latter printing is 1979-1983 which is 13.0x13.3.

"I have been looking at this stamp for about a week.."
Wert,
looking at these details for about a week would by itself cause eye fatigue and affect anyone's vision. Still, the perf 13 x 13.3 is listed as 786, (from pate 3) and does not show precancels...so the mystery remains....

Possible counterfeit?

Paul. I originally thought about that to, until I used some of my colour analysis software...Remember this, if a counterfeiter was planning on reprinting for monetary use, I would not myself do such low value and concentrate on only high value stamps.

Now take a look at what colour differences/similar when put through 2 different colour software programs.

1- It was bad enough when I was a printer trying to copy the exact same percentages of colours to match the previous run...I cant imagine how hard it would be for a counterfeiter to obtain.

2 - Take a look at how close the colours were from stamp to stamp.

FIG.A The colour of both stamp backgrounds are close enough to be acceptable for proof reading by a printer to start more printing.


FIG.B The colour of the lady slipper leave is acceptable also.

FIG.C The colour analysis of the "C" of Canada..Acceptable.

FIG.D Colour of background colour..Acceptable

I am pretty sure it is NOT a counterfeit.

I agree that your images are NOT counterfeit!

To be honest Robert, I am leery of that perf gauge overlay that you have..hoping you verify with a hand gauge?
Don

Good eye Don...

Don..I did a side by side perf test on top, bottom and both sides..Equal on all results..Am I seeing the same size precancel bars or am I correct there are TWO different size bars as I originally thought.

Robert

From the images, the precancel bars appear to be different sized. But as Peter mentioned, possibly mat change (including pressure, wear, stretch/shrink)?
Don

I should have been clearer as I actually meant adding the precancel bars to a real stamp increase the value of a retail precanceled stamp.

I know what you are thinking Paul..But really..First you have to buy complete sheets of Scott 711 stamps, then approach a sketchy printer who will produce counterfeit stamps for a cost...Pay for the dark room to burn the plate..Cost of the plate and ink and the printers time..WHY would anyone do that to produce precancel stamps that the money to be made is very, very, insignificant.

Or simply use a cork and cut lines to create the precancel lines on the 786 (that did not come with a precancel variety) at virtually no extra cost - and now a new variety. No expertise required.
