Washington - 4 Cents - 19??

Hi,

I try again and I don't see watermark.

Thank you!

Sorry to see that you're frustrated. It sometimes is, trying to see these watermarks is hard, especially S/L.

The single line watermark can be extremely difficult to see because sometimes there was only the end of a letter, that is, a small portion of a letter, that protrudes into the stamp. So, it is hard to see and can be mistaken for smudge or a postal marking. So, lets see what we can figure out in the circumstances.

Looks like the considered opinion is that this stamp is perf 12. That being the case there are only three alternatives: 334, 360 and 377. 334 and 360 are both double line watermarks and 377 is single line.

I would be willing to bet you that if there were double line watermarked, that you would have seen the watermark mark. D/L Watermarks are much more evident than S/L. So if this isn't D/L it has to be S/L since that is the only choice. There was no unwatermarked 12 perf of this stamp.

377. By process of elimination.
