Welcome, Greenfrost.
We often recommend that you have a look at
www.stampsmarter.com where among the features is a "washington franklin" identifier. It is very helpful in going through stamps such as these in a stepwise, systematic fashion to determine what you have.
This is perforated on all four sides, not a coil stamp.
So that eliminates several possibilities off the bat.
If you have a perforation gauge, you would then gauge the perforations and be able to further narrow the possibilities. By counting them, I would make it to be a perforation of 12 (both vertical and horizontal).
You are left then with three possibilities: a Scott 331, a 374, or a 357.
The 357 is on blue gray paper, and would be somewhat unusual to find.
From your photo or scan, the paper does not look like blue-gray to me, although I am not an expert, so it is most likely _not_ a 357.
That leaves either a 331 or 374. These can be told apart by the watermark of the paper. Either double or single line respectively. This is nearly impossible to do when it is on an envelope or postcard.
From the date of the card of 1911, it is probably a 374 which was issued in 1910, but it could well be a 331 which was issued in late 1908.
Either way, the 331 or 374 are extremely common stamps, issued in the millions and now not really worth more than pennies, if that is what you want to know.
