Greetings all:

I do not own this stamp. The image comes from the Philatelic Foundation's online database (Cert #459165).


If anyone has the time and patience to share an opinion, I'm VERY curious to know what evidence (given only this photo) leads to the determination that this stamp was "reperforated at right."

Thanks

By what percentage does re-perforation lower the catalog value?

It looks like the perfs on the right are a different shape. Darn good effort though. I doubt I would have spotted it.

A lot. First off, the reason for a reperf is often to improve the centering. So any value above cat for well-centered (SSV or SMQ) is out the window. Then maybe 1/3 off the cat value if not more.

Perforations should be looked at from the reverse. That is where much of the evidence can be found, such as a lack of pressure ridges. Also the sharpness of the edges.

Similar to what rslny did I moved the left side closer to the right and lined up the top hole. As you move down the misalignment increases. Not a lot, but there should not be any. While this digital manipulation is easy to do at home if I were to see this stamp in person at a show I would have no way to really see such a small misalignment.

I looked at the top and bottom perfs and noticed that they were not inline with those across from them. Tooth versus hole. I assumed that they should be.

Actually they should not be. Being slightly off is not automatically a problem either; pins wear down, pins get bent, and pins get replaced with new pins. So small differences can occur. Again, seeing the reverse is very important.

If I am reading you correctly, then this stamp is line perforated,
they will rarely match up.
if COMB perforate, then they always will, and should show a part hole
in each corner.

Stephen J, this issue and others of its era were perforated by pins on a free-wheeling roller. They do not align with each other except by coincidence. See the top and bottom perfs of this stamp.

Justfella, yes, you are no pro and you are guessing, wildly. Do you think the other respondents to this post are making guesses? The answer is that they are not. Your agenda of contributing misleading thoughts to threads is not appreciated here and elsewhere.

This is only going to create drama and falls in the area of forum etiquette (which is under the purview of the forum staff). Communicating opinions on other people's posts is best handled privately. There is a 'Send Message To Staff' link on every page and/or in many cases members can contact each other privately.

Members calling each other out publicly is always a potential train wreck and is best avoided.

Wow... never a dull moment in this neighborhood.

Many thanks for the on-point responses. This feedback inspired my diagnostic of another copy of the same issue:



I hope y'all can work out the rest. Peace.

I come in Peace
It's very hard to tell with the naked eye a well done reperforated stamp. Your example is exhibit 1.
It is clearly a professionally done reperf. I have gotten much better at distinguishing reperfs with a dissecting microscope that displays the paper thickness as if it was cardboard. By eye, I think most observers would say that your patient is fine, probably not the expertizerrs in the audience.

I agree with GMC. The PF and PSE have technological tools at their disposal now that can take examination to the next level. You can see the change when new certs overturn older clear certs. It happens a lot. Linn's made a comment in an article on these a while back regarding reperforated and regummed examples being plentiful and a certificate was recommended.

I saw this description in an upcoming Siegel sale extensions balance lot and thought of this thread. Love the "alleged problem". Perhaps a bit of sarcasm?
