Scott 596 1 Cent Stamp Mesures Out Right And Looking For Additional Insight

I believe to have a 596. Any help is appreciated.

mesures 19 1/4 x 22 1/2

Welcome.
The stamp dimensions are the least reliable method for IDing a 596; this is one of the most commonly mis-identified stamps in the hobby. So much so that one of our members wrote an article on it here https://stampsmarter.org/learning/I...arities.html

You are fast Mr. Don!

Translated from Spanish = "Don, you have a unique gift." See what I did there. :)

I just got this one. Other than the diagonal cancel, they sort of look the same. This one is 632. It measures like yours but the perforations are 11x10.5.

This one just came in today. Except for the blind perfs, yours looks a lot like this one. Yours actually looks more like 632 than this one. I might actually send this one in to be certified, it's just too close.

imodius: Save your money. Both of your stamps are 632. As to the one you consider a possible 596, the first thing to note is that the horizontal & vertical perf gauges are different. I simply measured the distance across the top that encompassed 11 perforations ... then measured the same distance vertically and found only 10 perforations. It is clearly perf 11 across the top ... so it must be 11x10 (578) or 11x10.5 (632). Made a quick comparison with known 578 & 632 ... and the result, not surprisingly, is 632.
Added: Scott tends to round/truncate perforation gauges to the nearest 0.5 whenever doing so will not result in ID confusion. A close measurement of the 11x10.5 series yields a more accurate 11.25x10.5. In a similar vein, the 11x10 (578-579) is actually 10.75x9.75. On the other hand, the perf 11 (551-573) really is 11 in both dimensions.

It's true, it is 632. You are right, both are 632. I will save my cash for the big find!
