Those Interested In O.h.m.s. Perf. Oddities.

Here are just a few that I have catalogued into my collection....There tons of these oddities.

Realize that Canadian O.H.M.S. perforations were perfed in 3 different sizes as the picture below shows.


Below is a good example of double (jerky) perfs.


Below are examples of missing perfs.


Below are examples of broken perf pins.


Below is an example of erratic roller pin spacing.


Below is a weird pin oddity.


This is the most extreme example I have seen with double perfs and tearing of the stamp itself.

Hi Robert,
Were the O.H.M.S. perfins faked? If so, how do you spot the fakes? If my memory is not failing me, I think I recall reading that the faker used the original perfin equipment; is this true? If so, that would make spotting the fakes almost impossible?

Hey Don

I would think that a forger would have to first buy lots of sheets of stamps, then find a criminal partner to reproduce the exact perfin machine characteristics that the Government does normally..I think the question you missed to ask and should be asked...To what end..??...Would not be a good monetary gain in my opinion.

Good read here...

I disagree, taking a <$1 stamp and turning it into a $100 stamp is plenty of monetary gain. No need to buy full sheets of stamps; simply take a 10 cent used stamp, punch a perfin, and you now have a much more valuable stamp. A reproduced perfin punch could be made at any machine shop.

Are you saying that O.H.M.S. fake perfins do not exist?

wert You should contact the following: http://www.bnaps.org/hhl/n-perf.htm

Here I hoped that "The BNA Perforator" was about perforations rather than perfins but I was wrong.

It would not be difficult for a forger to find sheets or part sheets of the stamps that were perforated OHMS. On used stamps, just past them on a sheet of paper, resembling a sheet, perforate them, and then soak off the paper.

Jarnick...makes sense but all the double perforations I have come across, have a cancel on them..I don't think the so called forger would develop a method of cancelling...I have gone through approx. 33,000+ stamps and only came across 1 or 2 double perforations.

Now for a forger to develop a process to forge double perforations, a couple of things must happen..

1 - He must have a sneaky employee to slip them out the door to start their forging process. (i have never come across any mint O.H.M.S. double perforation stamps, even in the 66,000 stamps I am looking through)

2 - The forger must has access to a perforation machine from another sneaking person.

3 - The only way I can see it happening is to get a hold of high value stamps sent out by postal Canada cancelled and used..That is a lot of time consuming gathering of these envelopes...Time consuming.

4 - The forger would have to acquire the same size perforation machines for Large, medium and small perforations.

5 - Now last part is to look at the double perforation, measure it, look for broken pin identification to match what the first perforation shows.


Robert

Just an opinion...Other opinions welcome.

Robert, you overlook the obvious. The forger had the original perforating machines, thus he needed no sneaky employee.

Your point about double perfs is well taken. They may all be genuine. Frankly, I've never been able to tell the difference between the forged and genuine perfs. Ken claims that he can and I have no reason to doubt his ability and knowledge.

For used genuine perfins I would expect there would be traces cancellation ink on the cut edges of the perfin holes whereas for the faked ones, if done as suggested above, the side of the hole shold be clean. It may be possible to see this with a microscope.
