Hi,
I have wondering the very same thing for the last couple of months...on and off research always ended up disappointed and now I see yours and it does come together...
I have see photo. A pair of Horizontal 1 cent Newfoundland Queen Victoria stamps from 1897-1901...Royal Family series...on the original envelope corner..
I have been looking myself to find out whether or not The punch is a not so funny joke like record guys or an actual cancel for the stamps???
Now you can see there is a cancel but out of ink or always very light..But then because I think some over zealous individual wanted to make sure these 2 cents stamps could not be used again....based on their poor machine they punched canceled the pair in one shot ..notice it is right on perforation line canceling both at the same time.
as well the impression remains very concentrated at the one area only of the whole normal circle....like the dropped the machine or had a warped cancel plate or something..
Anyway Here is our answers...Now the next step would be to the next level...what is a stamp worth with a Rare Punch hole cancel...because they as we see do exist.
hope this helps.. It helps Me!
I viewed some examples of these security punches but the hole for that punch has a mild extra notch in the hole pattern..and from what I see the 2 are not the same...as the other fellow stated " These may not be pertinent to your quest and I think he was right..
I am showing what is pertinent to your question..
Thomas
