2c Rose Red, Perf 12 X 10

I found this postcard in my collection and it appears to have a 2c Rose Red, Perf 12 x 10 423B.
The cancel is for a railroad, anyone know which one?
Who should I send it to for certification?

thank you.

Here is a picture of the cancellation.

I am seeing a perf 11 stamp.

Here is a link to compare.

rogdcam is correct, it is perf 11 on all sides. Here is your stamp comparing the bottom perfs with those on the sides and the top, you can see the perfs match.

and it's not rose red... it's carmine

Thank you for your information, I still have a couple of questions on the date and the RMS cancel.

I am looking at the 2018 Scott specialized catalogue and it lists Scott 425 as a perf 10 earliest documented use
at 10/27/1914, my cover is September 18, 1914 nearly one month earlier than the perf 10 release.
the compound perfs were issued in the same timeline of the transition period of perf 12 to perf 10 in 1914.
The catalogue lists Scott 461 as the first perf 11 with the earliest documented use at 6/24/15 9 months after my cover.
Can anyone help me understand how this perf 11 is on my cover at this time? Could it be proof of the perf 11 was issued before 6/24/15?

With what you have shown the stamp would appear to be the Scott 461 pale carmine red, its the timeline that is really interesting.

Any info on the cancellation would be helpful also.
thank you for your time and Happy New Year.

The year of your cancellation is too badly smudged to make out. The 14 which you reference is not the year.

RPO ID: The Mobile Post Office Society catalog lists a number of cancels for the Groveton & Boston route. One specifically is worded "Grove & Boston" around the top of the rim, which seems to match your text spacing. Another of them has the "4414" trip slug. Note the 4 interior slugs are changeable. For some reason, a blank is inserted at the bottom instead of a year date.

Although your card could be overpaid, it is more likely properly paid and thus from the November 2, 1917-June 30, 1919 time period when cards were 2c due to WWI, thus without any other information, I would date your card to Sept 18, 1918.

Thank you for this info, I love the history side of stamps.
I am still left wondering what stamp this is, when I go to my references, Scott 499 is the right timeline but lists 499 as rose and 499h as lake and 500 as deep rose all wrong colors.
Scott 526-528b issue dates are in 1920 2 years after my cover.
Do you think I have the scott 461? Thank you all for your time and commitment to this site.

Does this cancel add value?

This is not a rare stamp. This is an über-common 499, with a rather common Railway Post Office cancel. Had the cancel been clear (even though it is identifiable), it would be found in a Dollar Box. As it is? Not much, unfortunately.
