I have several varieties of "chiffres espaces" of type Groupe stamps from the French colonies.
It seems that only in these catalogs are these varieties mentioned.
The distance between numbers 0 and 5 of the overprint is 1.79 / 1.83 / 1.85mm: Gabon, Guyana and St. Pierre et Miquelon.
Please help me with no. catalog and quota for these stamps (MNH).
Thanks.

I find slightly different measurements in my catalogues.

Yvert French Colonies 2017 catalogue says that for all 3 stamps the normal distance between the 0 and the 5 is 1.5mm. The variety measures 2mm.

Scott Classic Specialized 2016 Catalogue says that for all three the distance between the 0 and the 5 is normally 1.5mm, but they say the variant is 2.25mm.

Gabon
Yvert #67 (1.5mm) - 1.95 euros
Yvert #67A (2mm) - 13.5 euros
Scott #73 (1.5mm) - $2.50
Scott #73a (2.25mm) - $14.00

Guyane
Yvert #67 (1.5mm) - 1.80 euros
Yvert #67A (2mm) - 22.50 euros
Scott #88 (1.5mm) - $2.10
Scott #88b - chalky paper - (1.5mm) - $14.50
Scott #88a (2.25mm) - $24.00

St Pierre & Miquelon
Yvert #95 (1.5mm) - 1.95 euros
Yvert #95A (2mm) - 60.00 euros
Scott #111 (1.5mm) - $1.90

Thanks a lot bob.
I still have 4 stamps that at first sight have the same variety.



Regarding the measurement method, I recently received valuable information from the "perf12" (D2 method). http://goscf.com/t/63170

The values differ from catalog to catalog, because I think different measurement methods are used (D1, D2 or D3, I think)




The recommended method of "perf12" seems to me the correct one, but unfortunately for these stamps of mine I do not have some with normal overprint.
There are 2 types of varieties (normal distance + 0.4mm -rare) and (normal distance + 0.8mm)
I'm not sure but I think my varieties (if they are genuine) are rare.
Thanks in advance if you can help me with the catalog numbers and quotas for the 4 new stamps.
I'm still waiting for the information from Dallay or Philatelix catalogs.

I remembered last night that I have a full set of 15 of these stamps from French Guinee. I went and measured them all this morning and I would say the catalogues are using the D1 method of measurement. All my 05 stamps had a D1 measurement of 1.4 or 1.5mm (both Scott and Yvert say 1.5mm) All my 10 surcharges had a D1 measurement of 2.4mm (Yvert says 2.5mm, Scott says 2.0mm) I would be inclined to believe Yvert on matters of French Colonies, and I have found other errors in Scott in my area of specialization.

Mayotte 5c on 4c
Yvert #22 (1.5mm) - 3.75 euros
Yvert #22A (2.0mm) - 33.00 euros
Scott #23 (1.5mm) - $3.50
Scott #23a (2.25mm) - $24.00

Gabon 5c on 25c
Yvert #70 (1.5mm) - 2.25 euros
Yvert #70A (2.0mm) - 13.50 euros
Scott #76 (1.5mm) - $2.00
Scott #76a (2.25mm) - $14.00

French Guinee 5c on 4c
Yvert #49 (1.5mm) - 1.80 euros
Yvert #49A (2.0mm) - 75.00 euros
Scott #49 (1.5mm) - $2.00
Scott #49a (2.25mm) - $65.00

Grand Comore 5c on 4c
Yvert #21 (1.5mm) - 2.25 euros
Yvert #21A (2.0mm) - 16.50 euros
Scott #21 (1.5mm) - $2.75
Scott #21b (2.25mm) - $18.00

Though as noted above, I'm inclined to believe Yvert's measurement of 2.0mm for the variation rather than Scott's 2.25mm

Thank you bob.
I downloaded from the net the picture of a stamp with normal overprint 05.
By the measurement method D1 the resulting distance is 1.25mm (???)
Can you post a picture with your stamp with normal overprint 05?
How did you perform the measurement? I use a digital measurement on a scan or photo.

The 05 ovpt. with wide spacing on Grande Comore, Gabon,Guyane,Mayotte stamps is found only in 8 positions in the sheet.7 with 2 points of seperation & * 1 with 1 point.
Guinee,St. Pierre Miquelon(except 35c) stamps with the wide spacing are only found once in the sheet *(1 point in pos.105.)

* Comparatievly rarer.

The D1 measurement on this is 1.5mm. I measured it with a 10x loupe with a mm ruler marked on the glass

I suspect doing an indirect measurement on a scan as opposed to a direct measurement on a stamp can lead to problems, depending on the settings of the scanner.

Thank you perf12
I wonder why Yvert-Tellier does not mention the 2 dimensions (1 point and 2 points)
That's why I'm looking for information from Dallay and Philatelix where it seems that both dimensions are mentioned.

Very good picture, bob.
I moved the cursor horizontally and wrote down the intersection coordinates with the vertical lines of the stamp frame and the overprint numbers.
I used a sufficient magnification for the best possible accuracy.




Knowing that the stamp has a width of 18mm, I transformed the coordinates into dimensions in mm.
I did not choose a very visible color and I rewrite the dimensions: 4.34 / 3.71 / 1.31 / 3.37 / 5.27 = 18 mm
I don't think I made a mistake, the image you sent is perfect and yet the distance between 0 and 5 is 1.31 mm.

That is why it is better to have at least a strip or block of stamps with at least one with wide settings to be able to measure with precision and be plated.
In the sheet there are 6 groups of 25 stamps.Each overprint has a different spacing from one another in the block of 25 (5X5).Thus they can be positioned with precision.Just measuring one stamp is not conclusive,but can just indicate a given setting.(normal,+1,+2).
