Canada 1452 With Accent Over "O" Varieties

I was looking at Canada # 1452 (sheet stamp, pane of 50 stamps, perforated 12.6 x 12.5, Harrison Paper "H", GT4) and # 1452b (booklet pane of 10 x (1452a booklet stamps) perforated 13.3, Harrison Paper "H", GT4) and I decided to go looking for pictures of its accent over "O" varieties which I am posting on here.


1452i: imperforate sheet stamp pair with accent over "O" from one known imperforate pane of 50 stamps (25 pairs)


1452a var: unique booklet bottom margin single stamp with accent over "O" variety (Coated Papers "C" not Harrison Paper "H")


1452a var: unique imperforate between booklet bottom margin stamp pair with accent over "O" variety (Coated Papers "C" not Harrison Paper "H")


Here is a picture of 1454i sheet stamp pair from one known imperforate pane of 50 stamps (25 pairs) for reference and comparison:

Jogil,
while Unitrade calls this an "accent", the double dots symbol is called a trema in French and a Diaeresis in English (also a Umlaut) It is a mark, in writing placed over the second of two adjacent vowels to indicate that it is to be pronounced separately rather than forming a diphthong with the first, as in some spellings of coöperate, naïve,etc... I'll submit my suggestion to Robin, prior to the next edition

Gilles le timbre: Would the word "mark" be a better description? I put together this listing above because "a picture is worth a thousand words" in dealing with stamp varieties.

Okay, let's see if I got this right:

A printing error occurred: the designer placed the umlaut over the wrong vowel.
Test sheets were printed and the error spotted and corrected.
The person in charge of destroying the test sheets did not do that.
He took them out the back door and sold them to someone lurking outside.

A partially imperforate pane of 20 made 10 pairs worth $1,250 = $12,500.
Why do we not call this receiving stolen property?

If not, why does this community not wonder about which lurkers are getting the "printer's waste"?

sak: You have a point here in that these are not regular issued panes that just did not receive perforations and slipped out to the post office, but this is an unissued pane with a printing error and without perforations. Thus, your reasoning on them makes sense.

Jogil, 'mark' would be a better word in my opinion. An Umlaut does not exist over the E - an Umlaut changes the way the letter is pronounced as in Umlaut A, O or U. A diaerasis or trema changes the way the word is pronounced as in Gilles le Timbre's examples above.

Gilles the word trema don't exist in any French dictionary ; it's not trema it's tréma ( since we talk about accents , put at least an accent on the e of tréma ) it's come from the Greek trêma that means point, the real word use to describe those kind of sign is "signe diacritique" ( that means to change the pronunciation ) the diacritique include the " accents, the tréma and the cédille "

But my point is . use accent on French words or it's not French ....

good point area 66. I knew about the accent on trema, but my keybord does not allow accents...(or I don't know how to switch to a french keyboard).

Gilles, if you like to put an acute accent on the word tréma, hold the 'alt' button and choose 0233 on the side keyboard on your computer. It will print the letter 'e' with the acute accent over it.

Thanks Peter. I learned something today...was worth waking up and living that day

There's a good article on this here: http://mentalfloss.com/article/5893...about-umlaut
