Hello Magic,
the best way to isolate perforation varieties, if you are unsure,
is to measure the stamp, by placing it alongside a stamp of known perforation.
(butt them together, perforation to perforation)

If you exhaust all possibilities, then send it in for certification.

Reddish brown 30c could be any number of issues. First check paper type. Is it white paper or granite paper (small colored threads in the paper). This is an easy determination.

Then measure the perfs on top and right side.

If white paper, perforation choices are 11.5 X 11, 11.5 x 12, or 11 3/4 both sides. The right side perforation measurement is going to be the decider here. Always choose the closest measurement and be objective.

If granite paper, perforation choices are 11.5 X 11 or 11.5 x 12.

Given the color and the rarity of the 11 3/4 I would assume you have one of the more common types.

Granite Paper (Brazil)

There is also the possibility of watermarks.

Hello! Just nowe iam not home! But I knowe that IT has the thick Cross the paper type I most check!thanks for all the answeres its wery welcime!#9993;#65039;

Zumstein catalog has very convenient templates to compare Standing Helvetia perforations.
Zumstein Spezial also lists many color shades for each issue, some of which are rare and valuable.

Generally, I recommend using a specialized catalog for every country that you collect seriously.
Expertizing is expensive and time-consuming; in most cases, when we are not talking thosands of dollars and museum-like quality, being a bit of an expert yourself pays off.

This stamp does not have the same perforation on all four sides; here is the stamp's top perforations lined up with the sides and bottom perforations.


Magic70, you have had a number of posts where incorrect perforation determination caused you to make incorrect identifications. (i.e. https://goscf.com/t/49927 , https://goscf.com/t/48331 )
I also do not understand the noted perf measurements in your first post (top/bottom or sides?) but maybe there is a language issue at work here.

It is understandable that some perforation determinations can be a bit tricky but it would greatly help if you called out the perfs for all sides. Determining perforations correctly is one of the most important skills to master. Is it possible that you could post pictures that include the perforation gauge?

hello! howe ewer I use it on this stamp I have come to the conclousion of 11 3/4 it dosent messure 12 and not 11 1/2 iam no master at this just a amatör trying to get it it right but I have been a master of ather perfektion! so just lerning here!i will take in mind kritikely that it can be a nother perforation! I will go back and messure several times!if iam wrong the the instrument is wrong I think!and I messure the upp side first and then the left side of the stamps! regards

Given the comparison of side and top perfs in Don's post above, your stamp is 11 1/2 X 11.

The conclusion: it cannot be the 11 3/4.

From my experience, measuring the perforations of early Swiss stamps is a little tricky but pretty easy if you apply caution. I use a very simple perforation gauge and the trick is to go with the perforation measurement that is the closest and makes the most sense given other observations (e.g., top and right measurement obviously different). You can always use a more accurate gauge if there are doubts.

In this case, its pretty clear the perforations on the top and right are not the same, and the right perforation measurement is smaller (larger spacing) than the top. The only choices in which the top is larger (smaller spacing) than the right side is 11 1/2 X 11.

sorry!but I have the stamp and the instrument for messuring its still 11 3/4 all four sides have messur it several times and its pretty clear!

Why not add a couple of scans with the perforation gauge against each side of the stamp?

Yeah, I want to believe. It would be great to know you found such a rarity. Please submit more information so we can understand how you arrived at your conclusions.

But how do you explain what Don did with the cut and paste to show the top perfs were not equal to the side perfs? You know, you can do that yourself since you have the original scans.

You can also compare your stamp to a known 11 1/2 stamp in a side-by-side scan. You could also post a scan of the back. You could scan at higher resolution so we get a good view of front and back.
