Papal State _ Couple Of 5 Cent From 1870 , Perf. 13 ? Sassone 25A?

Hello!
Millimeters were used in the image.
the three columns of values, from left to right, are the reference measurements for the measurement of 10 15 or 20 teeth, always from left to right.
if the measure "falls" in a rose it will have its reference point.
trying to measure an image using the basic measurement its same width (26 mm) seems to me to come out very interesting dimensions, in fact all three tests match. do you believe that this method can be safe and reliable?

Just a gut feel here ,but the ink cancel on the stamp doesn't look like the ink below the stamps which is on the cover . I can't be sure from a scan but doesn't look right .

Oh well, I have the text inside with a date down left, 23 of 1870 from veroli (written).
The only cancel readable is from 23 gen 1870 as wrote in the lettter.

thanks for your opinion!

Has been bougth togheter. Have same Graphic quotes.
the ink of Veroli is the same of the cancel on the stamp. it start to vanish first of the stamp ending to vanish on the stamp. sometimes happen.
in the last image one is the perfored one the not perfored . a piece of color small but not too much fot the dimetion of the stamp has been take from a stamp to another.

No, it is not reliable nor safe. Using one stamp from one issue from one stamp-issuing place does not make a measurement system. This is like catching one fish in the ocean, then saying that anything that does not match it is not a fish. Declaring some ranges of measurements to correspond to certain perf measurements is absolute cheating. Note how the "system" falls apart at perf 14 and will only get worse at actual perf 15 and actual perf 11.

Perf gauges are defined by baseline 20mm measurements, not the other way around. It might make sense if you said that this issue measured perf 13.03, though you would have to prove it by measuring hundreds of copies. Further, I also doubt that one could specify a number that accurate since 19th perforation technology wasn't accurate down to plus or minus 1.5 milllionths of a mm.

Thanks for the replay. You said something about the misures relative 20 mm. Using the same tools I find exactly 13 empy in 2 cm. Bit as we said everething could be and errore

i have a question. could help the fact that the 5cent in II Issue is large 26 and , the only quote that satisfy those 26 mm is exatly from the outer to the outer boarder upright double lines ? I ask because that distance is the same on the couple from III issue. In both the the upright are 19mm in both the oval , looking the shorter dimention quotes the same.
i know that II is 26 x 22 mm and III is smaller 25 x 22 then or the entire grafic ore something had to change alot? I'm in error? at the and th differences of dimentions ar not few 1 x 2 mm

the first is a classified 25a
the second a couple classified 26b

II issue 26 mm for 22
III 25 x 20
In the 25b I can see perfectly both lines up and down,
in 25a I have same trouble a can not see them perfecly in the same time.
the stamp is 2 mm shorter and 1 mm smaller could be a detali that demostrate?
i has quoted the inner double lines in my 2 couple II and III have same dimention.
i wait for you

Those are the 2 most interesting read with the tool to read the perforation.




Seems like if there is a sort of kind of error. To perfor is a wheel with right elements to perfor .. and if has been the moving of the paper under / during the perforation?

as is possible to see, the first image is centered at the center and in the most far zone od the two sides demostrate not a same king of walk..

in the second image is shonw the fact that for alot of perforation is the same walk,from rigth to left, while at left, in the most far zone, the walk is missed again.

Have a nice day

Perforations often do not exactly to match the 1/2 gauge like that. They could easily be something like 13.3 instead of 13.5. Catalogs typically just give the closest value to what they really are.

Dear Bill,
if I had understood your point of view you think that could be a little bit less then a 13 and 1/2 then instead a 13,5 a 13,3..... right? I understood?

In pontificio I had read that the sassone number 25a is 13 of sure and came from the II issue ( same paper) and is possible to recognize it for a very good perforation tha is 13. In this case how may I catalogue it? is a particular or voulgar perforation for Pontificio III Issue?

on stamp world is wrote that the III issue usualli is 13 and 1/4
Here more near 1/2, not 13 or 13 and 1/4 of sure.
here other two measurement at 13 1/2
