Rotary Press

good Saturday, Could anyone give me some info,
I am trying to figure out the diff. between
flat and rotary press.

This link gives a quick overview. It doesn't really get into the more general topic of presses. But does help in identifying the stamps you've pictured here.

Hi Gracie, for a moment I thought you were joking! Right above this thread is another one titled 'Scott 613 stamp '!
It not only gives you some of the things to look for, it talks about the same stamps you have! Good luck!

NO, and I saw that,
I am trying to figure out the perfs on it.
I found 5 of these stamps in a 4lb box of stamps I have.

Do you have a perf guage?

yes, I got 11 on each side.

So that would make it a scott #610 or 613.
If it's a #613 it's book value is $45,000.00
But to be a 613 it has to be a rotary press version of the perf'd 11. One way to tell is to measure the image height. It needs to measure 22 1/2mm not 22 1/4mm of the flat plate version.

The two in your post do not appear visually to be 613's.

I'm lucky when it comes to these stamps in that I have an imperf block (only flat plate printings) and a perf 10 block (only rotary printings)and I can easily compare printing images.
