Please Help To Identify...can It Be Scott 361?

Please kindly help.
Any hope that I have Scott 361? ))
Thank you.

Aurora, probably not. But if you use the "search" function above and type in "bluish paper" you will find several posts explaining how to identify bluish paper.

Dear Peter,
I always try to search the Forum.
Many discussions here do not include any pictures - so, it is complicated to understand what they were talking about.
I didn't know that main clue of Scott 361 is BLUISH PAPER.
Thank you.
If it is not 361, what's the number?
351 doesn't have perforation on the sides.
And what would you say about the third one? It is not perforated on the top.
...please help me...))

Found online:

Aurora, have you tried to check for a watermark on these? Assuming that you've checked the perforations & found them perf 12, I think your choices are 335, 361 or 378 (with 361 being extremely unlikely). Someone please correct me if I'm wrong, but I believe the blue-papers are not watermarked. 335 has a double-line watermark while 378 has a single line watermark.
One reason for these not being 361 is that they are used ... all of the Washington/Franklin blue-papers, while scarce in unused condition. are actually much rarer in used condition.
Finally, if you look closely at the stamp with a straight edge at the top, you'll see a horizontal "guide-line" above the design. These stamps were produced in sheets of 4 panes of 100 stamps each ... the panes were separated by horizontal & vertical guide-lines. The 4-pane sheets were eventually cut apart along those guide-lines. I would guess that your stamp with the straight edge probably came from the top row of one of the two lower panes in a 4-pane sheet. Note that a straight edge should appear on one side of any stamp from an outer row (top/bottom) or outer column (left/right) of a pane.

Always start with the assumption that you have the most common variety, not the rarest.

The first step is to identify the design (which you have done), next step is to identify the perforations. #361 are perf 12, the images supplied do not appear to be perf 12. Lastly, many of the 'blue paper' threads in this forum mention the need to scan blue paper stamps on orange background. If the stamps are perf 12 then scan them on an orange background.

Thank you for your comments. Really helpful.
I didn't expect to find rarity, I just couldn't find any other number for "Blue 5c Washington"!..))
Actually, I have more stamps like these...

Thank you for teaching me!! *

Top two are #504, bottom one is either #335 or #378 depending upon the watermark present.

Hey sry, I m rly new to this and ya, found an old stamp album I got maybe 15-25 years ago from my grandmother

i m looking into it since otherwise I would play computer in my spare time^^ so I m aware that I dont have any knowledge yet but a perf gauge and this stamp.maybe someone can tell me that s no scott 361 because idunno. perf is 12 (sadly one side is rly messed up :( ), and looks rly blue/greyish especially beside the other stamps on that site of the stamp album.sry about my bad english, I m no native speaker. thank you


ah to add, the backside doesnt looks that bluesh like the front imo

The front looks bluish because of the color ink used.

Peter

thanks!
