Need Help Identifying 557c?

I don`t know what to think. I guess it may have had enough of a margin to have been re-perfed...

Hi again,

I pulled mine out again last night to look with the added insight from the information here, & I do have 3 of the lighter coloured stamps measuring approx. 22.5mm. the two darker being 22mm.
As "cfrphoto" said it also reads 10 perf. all round so I guess another 586.
Funny thing is the other two keep coming up 11.5/11 perf. Probably just me & my less than ideal perf. gauge because there is no listing for that in my cat. But strange it's only tops & bottoms reading 11 & a half I thought. They all seem to have different types of paper too. I'll try to scan tonight & post a pic.
Thanks again for your input & time.

Jad,

You will need to a Kiusalas US Specialty gauge. A modern version called the Precision Multigauge has the same capabilities and more. What you have observed is that the rotary 11 x 10 1/2 stamps (the two stamps in the bottom row) do not have the same gauge 11 as the straight edge flat plate stamp on the left above.

The Kiusalas gauge is based on English measure and lists the gauge as the distance in thousands of an inch between pin centers. The flat plate perf 11 has a pin spacing of 0.072 inch and was labeled 11-72 by Kiusalas. The rotary gauge is 11-70 by 10 1/2-75. While the difference in gauge is significant, 11-72 and 11-70 are both perf 11, even though the rotary perf 11-70 is almost perf 11 1/2.

I suggest that you apply for membership to the United States Stamp Society. All of this information and much more is in the on-line archive of all of the "United States Specialist" back issues.

Thank you Clark for the great details and your time, very welcome input. I see where I've gone wrong 3 times now, I will find & grab one on line ASAP(I hope). Really looking forward to getting into my U.S. stamps.
Joining sounds like a great idea too.
Please excuse the late reply, life got real here ;)
All the best.....Jad

557 (a) imperf help please.
I found this stamp in my late fathers album (actually my great grand fathers )
I have not found a similar one online .
Could anyone please assist in more information.
Thanks

Scott 602. A poorly centered coil stamp with natural-cut straight edges at top and bottom from the coil. Right side cut by the user when passing through an affixing machine, which also made the generous cut on the left side leaving almost all of the perforations.

Hi guys. I am new to the site. I've been trying to identify if this is 557c. It's imperforate only on top and perf 11 on both sides and bottom. Can anyone help me identify which one this is?

Worth 10 grand?

Welcome jregusci2.
No, it is not a 557c. You can learn more here

Thank you Don for the information

KGB, I wish the Scott catalog has said Partially perf 10 at top or bottom.
If they ever change it will be a long time.
Meanwhile there's no reason we can't be more careful and explicit to help newcomers, Everyone say, Partially Perf 10 at top OR bottom.

And let's be careful out there. anything cataloging over ($100?), always start with expectation you do not have the rarity, make it prove it to you. Many altered stamps are out there.
