could it be unknown Eire coilstamps from 1939/40?

Thank you for the additional feedback.

It's probably right what you say Rod222, that someone has used the scissors, jeez, then it's a bad job.

I interpreted it to mean that no one would try to fake with such a bad job...and then thought that they were "real" coils with crooked edges.

But since this one has perf 14 3/4, it must be scott no 107.

Then there is a new problem, is scott nr107 previously known with "SE" vm??

The only variant for No. 107 is No 112aw. It has invert wm "E"

Is then conclusion, this is scott no 107 with wm "SE" which is not listed??

I can't help you with your stamp but I would suggest that if you have something that you think is rare you should really be consulting a Stanley Gibbons, Scott or a specialised catalogue rather than using Colnect.

For example the second stamp in you opening post, Colnect says it has a stated perf of 14¾.

This is SG 112 and Scott 107 which both catalogues (SG 2023 edition and Scott 2009 edition) have them as perf 15 x 14 not 14¾ as per Colnect.

A quick check of a SG 112 reveals the vertical and horizontal perfs are different so Colnect is wrong.

I am of course completely open to the fact that I may have assessed this completely wrongly. I guess that's why I'm asking for input? Because I'm unsure and would like to hear other people's opinions.
And if you don't have the catalogue, you have to ask others on forums or use websites. But it's even worse if Colnect also has errors in its data...unexpectedly, since Colnect is surely to be considered a "good" reliable source?

so, Rod222, if Colnect is wrong then that explains my confusion? :-) regardless of whether these are cut or not, perf 14 3/4 and wm "SE" are the hard facts for me. Will look up sc#66 as you say ;-)

Salentin, I too was surprised that there could be such wide margins AFTER clipping. How wide are they with tags? But seeing that they are horribly crooked and have small cuts etc. I have no high expectations that this is anything valuable.
I do this because I think it's damn fun to find some stamps that seem out of the "normal" and enjoy the childish excitement of what it may and may not be.
And I have little, almost no experience at Eire. I spend most of my time on US-Frank/Wash and Norway (my homeland)

Rod222, most of the time I follow this method: look for what confirms that it is NOT what you think/look for/hope for. Then you will find the important indicators faster ;-)

Colnect is a wiki, meaning that the data is entered by many volunteers which is very different from how a catalog is edited and published. There are over a million Stamp listings from a multitude of catalogs. That is a massive amount of data to compile! Colnect also relies on input from users to help spot errors or missing information.

I currently am in the process of adding the Hibernian catalog data to Colnect and volunteered to help edit Ireland. If you are a colnect member you can submit suggestions regarding errors or missing data yourself by using the “Help Improve our Catalog” box.  You are also welcome to send me a message here or on Colnect.

I think the key thing to see is if the edges are perfectly parallel. Sheesh I wrote perpendicular- MUST HAVE COFFFFFEEEEEE

Thanks for doing that djcmh but the stamp is 15 x 14 not 15. The horizontal perfs are clearly different to the vertical perfs.

The stamp from Colnect with the horizontal perfs turned 90 degrees and compared with the vertical perfs shows this.

michael my mistake I have corrected this now it is 15x14 got confused with the discussion of the coil

Interesting to note though that the OPs image in first post does suggest the perf is closer to 14.75 than 15. This shows another issue - most catalogue publishers did not start measuring perforations to the nearest quarter until the postwar era. Generally you find few quarter perfs in classic era stamps.  Most perf gauges from the classic era only had 0.5 gradients, so when newer, more precise gauges began to be made later, catalogue publishers generally did not go back and remeasure perforations to update their data. So while the catalogues all say 15 horizontal on this sheet stsmp, higher detailed perf gauges indeed may show perfs closer to perf 14.75.  Environmental factors can also affect measuring perfs.

But bottom line, coils of this stamp are perf 14, sheet stamps are perf 15, and anything looking like a coil with a perf  closer to 15 than 14 is a fake coil stamp

Yikes! absolutely not Nordic Traveller
I understood your route.
All's good 

I was actually responding to the ether,
you will come across this regularly, esp with US varieties.
I was responding, to encourage the application of certificates.

Any responder to help assistance, will face this sometimes touchy margin, between dogma and opinion.
Oft it is easier to not help at all, but both lose that way.

Spar away !
