I Believe This Is A Scott's Number 596? Need Help Please!

It's measurably wider than 3/4 of an inch and measurably wider than 7/8 of an inch it's perfs are 11 by 11.

compare its size and perforation with other 1 cent stamps of the same design, either by hand or by scan.

Compared it to the 596 is on Siegel site, seems to be the same?

you have to compare to real stamps.
(by the way your image does not help much)

A little lite reading.

Hi JimmieJoe,

There are three varieties of the perf 11; 552 flat press, 594 rotary press, and the 596 rotary waste.

One way you tell them apart, among other things, to measure the size of the printed image in fractions of millimeters.
This is why you cannot measure an image.

Comparing to known examples of the cheap varieties with the corners clipped away is the best way to see the difference in sizes.

here is a few scans of some genuine to compare

Thank you all for your help. I appreciate it so much. I'm trying to upload some better pictures. I've used a when thousands of an inch slide ruler with a dial gauge to get the most exact measurements I can so I'm thinking maybe the only way to know for sure he's just to send it in and get it certified?

Trying to measure a stamp design is the least reliable way to determine the stamp's identification. Your stamp is not a 596.

The first step is to determine the perfs. Your stamp is not perf 11 x 11. We can tell by comparing the perfs from the top/bottom to the sides.

Here is your stamp with the bottom perfs compared to the side perfs, note that they are not the same.



When trying to identify stamps, always start with the assumption that you have the most common, not the rarest. This is due to confirmation bias. If you start thinking that you have a rare stamp is it much harder to be objective. Our excitement will cloud our judgment.

Addiitonally, when posting images it helps if you post the stamp along with the perf gauge.

There are so many different varieties of this 1 cent green Franklin stamp as found in http://www.stampsmarter.com/1847usa...ntifier.html Yours appears to be perforated 11 x 10.5 for Scott 632
