Yes, it's perf 10.
It's best to use a Kasiulas guage when measuring perfs of Washington-Franklins.
Your stamp is one of the following, depending on watermark, color and type:
Scott # 444, 453, 454, 455, 491, or 492
I can not tell from the scan which type it is. If you can determine type, you may not have to remove the stamp to search for watermark. The 491 and 492 are not watermarked, while all the others are single line watermark.
I agree, it appears to be a perf 10 coil. This means it might be one several Scott numbers; 444, 453, 454, 455, 491 or 492. You can review these here

The first thing you can do is check for 444. Measure the image width. If it's 19.0 mm, it's Flat Plate and thus 444. If it's 19.5 mm, it's Rotary Press. There are 3 different Types. Type III is common both with (455) and without (492) watermark. If it's Type I then it's 453. If it's Type II you will want to have the watermark checked because a 491 on cover catalogs for $1,100.
My guess would be 492 given the date on the cancel, but there is always hope!

It's rotary printing and type III, but I'm not sure how to check for a watermark on a cover.
If it's Type III then it's a common stamp and not worth the effort to detect watermark. The 3rd Bureau is notorious for difficult to detect watermarks, especially single-line watermarks. If you can see a single-line waterwark even on a stamp off-cover you may be lucky, and you can never be sure that not being able to SEE a watermark means it isn't there. 338 is a GREAT example where you might swear there was NO watermark until you realize unwatermarked isn't one of the options.
Happy hunting in the 3rd Bureau!

I do want to add that although this stamp is probably worth nothing, the postmark is rather interesting (a precursor to the zip code postmarks) and may command a premium from the right buyer!

So maybe this will be easy because I'm making it too complicated, BUT here it goes.
This looks like a horizontal coil and a perf 10 vertical (I used my gauge to measure). Unfortunately, I can't seem to match it with a Scott # and I'm soliciting StampoRama's help.
Thanks in advance for your help.
