These are perforation 12 . They are on covers so I can't see the water marks. Stampsmarter says they would be #332 or #375 but how do I tell with out the water marks? The postmarks are 1911 and 1912 so that don't help.Thanks in advance.
The difference is the watermark; 332 is a double line watermark and the 375 is a single line watermark. With the stamps on cover, the only way to know is to remove the stamps and check the watermark. If you remove them, you can remount them using a hinge. Whether or not I decide to remove stamps from a cover to check on a watermark depends on the value of the cover and the value of the stamps.

Both 332 and 374 have minimal values as soaked-off used singles. With the cancel dates of 1911 and 1912, the odds are they are all 374. I would strongly recommend leaving them on the full covers and be satisfied that sometimes one is left with 2 possibilities for a stamp ID and that the value is in the full cover - "postal history" as I mentioned in another of your posts - which will exceed the value of the soaked stamp, whatever the ID might be. Also, please show us several complete covers which you find interesting. You might be surprised what this board can tell you about them.
I was afraid of that . I am not sure about taking them of the covers.I wish there was a easier way. I am just learning about these stamps and learning how to put pictures on here . I will put some pictures on of the whole envelopes and stamps when I get better at it .Right now I am just trying to identify all these stamps. Thanks to you Don and John
One of the best pieces of advice I received many, many years ago was something close to, "Leave all stamps on covers and paper if there are any postal markings, addresses, city cancels, etc. until you are comfortable with your knowledge of these. You can always get some more stamps to work on for a few years." I would have ruined a bag full of covers had I not listened. Search on this forum for some interesting postal history of covers. It will make it easier for you to set them aside and work on some other stamps that you have. Good luck.
