1923 George Washington Different Perforation

It wasn't bloody easy taking those pics ! but all I can say is those pics don't do it justice .. it looks more like it in real life by the naked eye … I look forward to hear from you all on what's your feedback

Oops one sec I forgot to add a pic of the back side of my stamp

Roni, I believe your pictures would be much clearer if you'd use black paper, not with all those wiggly lines ?
And if you need a perforation gauge you can print one from Stampsmarter, www.stampsmarter.org .

Hi all !
And yes Peter I do have a good perforation gauge I got no issues being precise measuring perforation on stamps … earlier I miss understood Jack Kelly when he asked me that question my apologies

Cheers

There is a quarter of a millimeter difference in the width of a 632 (I think that's your template) and a 594. To find that you need to line it up left to right quite exactly. From the picture I'd say it does not look any different in width and so is a 552. (Top and side perfs are the same - perf 11 apparently.)

In my opinion the quarter mill can never be detected if the camera was not aimed separately straight top view vertically looking down individually at each side.. otherwise it's mission impossible it's how I see it …

Cheers all and Thanks
Roni

2bOrNot2b - It may just be my eyes or your picture/scan but the 1c stamp you used as a template (with the Baraboo Wis. overprint) appears to have been a double transfer variety.

Hi Caper123 what does a double transfer variety means when it comes to stamps ?! ….

Cheers mate

Rather than comparing your 594 candidate to a 632, why not instead compare it to a known 552 (flat plate sheet stamp) and/or 597 (rotary coil)? The 552 & 597 are both extremely common stamps. If it is a 594 it will be the same size in both dimensions as the 597 but noticably wider than the 552. If it passes both of these tests, have it expertized.
Added: Incidentally, the idea of comparing a possible 594 with a 552 & a 597 arises from an excellent Linn's article, a link to which was provided by someone in another "is-this-a-594" thread.
Added: Took a little searching, but I located the link ... thanks to patg23 for the original link.
Copying the link seems to be beyond my current expertise. See the fairly recent thread with Valuation Conundrum in the title.

Ok Got it ! Will do and Thank you sir !

This should be the link provided by patg23 mentioned by JLLebbert

It does not appear to be available though.

The original link still works when used from the original thread.
Will try this accessing it again here. Seems to have worked that time. Do not know what I did wrong the first time.
