Pretty sure it's a #562
Just can't seem to get the perforations figured out
I gave up (need a better gauge) couldn't hit 11 on any side
11.5 top and bottom
10 3/4 sides

#642 would explain the 10.5
Not the 11.5 or am I off

U.S. stamps are NOT perfectly 11 or 10.5 etc. The catalog rounds off to the nearest half. This issue is actually slightly more than 11 at top/bottom as you are finding.

Have you calibrated you perforation gauge against a known standard to see that it is 2cm between the marks?

Your stamp is nominally 11 x 10.5 for cataloging purposes.

Ideally, should be around 11.25 x 10.49 for such Stickney rotary press printed stamps.

Your stamp has numerous small vertical creases which will collectively decrease the width very slightly and thus increase the apparent perforation rate. You do not have a error or oddity, but rather a damaged stamp.

Just Fella,

Can you post a scan of your perf gauge?

A large number of state revenue stamps are perf 11 3/4 and your gauge actually has an 11 3/4.

Ignoring the Precision style US gauge, yours is the first I have ever seen with an 11 3/4! I'd like to get one.

Thanks in advance!

Ok so I'm starting to think something is off
Paper expansion
Gauge calibration off or something I don't know
But I've got a few more reading at 11.5 x 103/4
So just thinking something is wrong now
All my stamps are kept in the same location all covered and controlled (best I can)

So would the franklin's be #632
The Jefferson a #641
And the Monroe's #642
Being 11.5x10 3/4 (moisture in the paper) they would be 11x10.5?

To check the gauge, use another ruler to check against the ruler on the gauge. Some plastic gauges can be unstable. The readings appear to be 1/4 gauge higher than the usual for these stamps.

I've checked on a few gauges all seem to be the same?
I read some other stamps just fine

Aside from the perf differences would I have identified them right?
