Sheet With No Plate Block Number

How do you find the plate block number when the sheet doesn't have one?

You must do better with that question. Maybe post a picture of the sheet or tell us the Scott number

Peter

OK
Thought there would be a generic answer, but here is the sheet without a plate block number (or, at least I can not find one).

Look in the lower right, there's the #.

@ Stamps62: "Look in the lower right"

All I see is either "11111" or "77777".
Neither one work on Stamp Smarter.

TG I didn't see any "ediy-bitty" eyes! HA!

What do you see?

If you enter 111111 into Stamp Smarter, it will return all Scott numbers with 111111, including your stamps as shown below.

NOTE, you are entering only five "1" (11111), the [plate number is six "1" (111111)

Stagedew, I know this can be confusing. When the BEP ( Bureau of Engraving and Printing ) was doing all the stamps they were putting
a plate number on the sheet. As you now have seen sometimes two numes, one for each plate used. At times this got ridiculous with some sheets showing a whole row of plate numbers. By the way, those were the actual plate numbers, etched on the plates.
A few decades back the numbering was changed and now each plate used just shows a "1". The sheet you show was printed using six different colors, hence six "1's". You can tell they are printed by different plates by noticing that they are not always lined up perfectly.

OK .... Thanks a lot studebaker and petert for staying with me on this.
My wife just point out to me (as she has said many times before) that I am partially color blind, and thus I can not/could not see the yellow "1". Therefore I was entering only five "1's" into Stamp Smart.

To be fair, there are quite a few of us who find the yellow digits of plate numbers difficult to see. It's also much easier to detect the presence of a yellow digit when it is not at the front or end of the plate number.

Just a needed (for me) clarification: I was under the impression that for multi colored issues, each color required a separate plat (starting with #1) and that a six color scheme required six individual plates. As the plates wore it was changed & the plate # would change accordingly. example: first run of the noted issue required 6-plates thus the '111111' plate number. if the plate used for the red inking was changed it would be etched at '2' making the plate number for the subsequent printings '112111'

Eligies, that is correct. That is the reason there are still different plate numbers found on Plate Number Coils sometimes.

Thank you Peter4522. With all the changing techniques in the production process & the onset of the digital processes I thought maybe I had a misconception on the engraving, inking, printing process.

No, nowadays a new plate that replaces a worn plate gets a #1 again. The only time they give us a #2 is if they change materials or production methods.
