Shown above is a 5 cent Washington Perf 12 stamp, sitting on a black piece of tile with a few drops of Ronsonol on it to help detect the watermark.

To me, it looks like a double-line watermark (but as you guys know I've been wrong before). I'm also a little unsure whether this is "blueish" paper or not. I'm not feeling super confident about making that call and was wondering how one makes this determination as a beginner.

As always, thanks in advance for your comments and patience.

Appears to be a single line watermark - #378.

Edit: Blue paper is not really blue at all. The 5cent Washington fools a lot of people because the blue ink can make the paper look blue. Blue paper actually looks grey and the best way to determine this is to scan on an orange background. The orange background makes the grey paper color pop, here is an example of a blue paper (on left).

I'd never heard of using orange background for this!

Thanks for the lesson, Don!

re: Single-line or Double-line watermark? Blue paper?

First of all, I agree that it is a single line watermark (the letter "S", in fact).

Secondly, Don's suggestion for using an orange background is BRILLIANT, but I had better luck with indirect lighting than the direct light of a scanner.
