Measurements For 1cent Franklin

Can any one help me on this one. I am trying to identify a few one cent Franklin stamps and they are consistantly measuring 19.25 x 22.25 on my digital caliper. Has anyone ever came across this or have any thoughts?

That is pretty much correct for the rotary press stamps. What perforations are they?

They are all 11 x 11

How many do you have like that?

I have 4. All are used. Two of them are still together. Three of them have more or deeper lines in the portrait, could this be a double transfer? Is a double transfer possible on the rotary press? One of those is also on the blueish paper. They are all the green, or deep green I would say. I know they are not the yellow-green. I will try to upload photos of them.

Better question- Does it have the words "ONE CENT" or the numerals "2 CENT 2" at the bottom?

I am sorry, I should have said that. They are the 1 numerals with "CENT". They are like the Scott #594 & 596.

Scott #552 Perf 11, Flat Plate, Series of 1922-'25

Can I ask how you came to this conclusion?

Yep. It's Green (as opposed to yellow-green), Perf 11 (as opposed to 10 or 10½) and I can tell it's flat plate just from looking at it. I'm sure others will chime in but I'm pretty certain. Plus I'm looking at a specialized catalog as well as my personal albums for reference.

Edit:
I think the very first one is something else though? It's yellow green on my monitor anyway? The others though I'm pretty positive on the ID.

So can the measurements on the flat plats be larger than the 18.5-19x22?

Let's see the back. ILS is probably right. I have a set of calipers I used to use. But really they aren't the best. I know they are measuring devices but when it comes down to .250 mm difference your eyes play tricks on you. I use a Sonic Imagery Lab to measure.It has a go-no go for the rotary issues. If you have a Scott 599 to compare then the color and size will match it. The rotary waste was made from the horizontal and vertical coil stamps.

The green ink on the back is a sure sign they are flat plate printings. Don't worry we have ALL done it. I've been rich several times until I got someone else look at them.

Hah funny :) I am just starting out with my first collection I recieved and you can't learn everything on the internet. The measurements is what got me. I know they are dead on. So seeing the ink on the back is a dead give away that they are flat plate, and is that true for all stamps?
