Thanks for posting!  I haven't done much with uS stamps since I was much younger. So hopefully others can chime in.  For stamps from other countries, with exception of some of the stamps that have fugitive inks (water soluble) I typically soak is warm to hot water with a drop of clear dish soap, after which the stamp(s) whether just a cleaning, or removing hinges or from paper, are transferred to another bowl of  warm to hot water only, after which they are placed on a towel to remove most of the water and then moved to drying books.  mIf I am trying remove stains or the effects of time, I have some petri dishes I will place water with hydrogen peroxide, set aside with a timer, and then after a 20 - 30 minutes I will remove and place in a rinse bath.  I have left stamps in much longer (meaning OK, I forgot about them)  with few ill effects, however I did have one stamp (which I cannot remember what it was) that I reduced to a white stamp with a very clear and distinct postmark  (I have wondered often what stamp it was so I don't subject another one to the H₂O₂ bath.  I have also toyed with enzyme cleaners/detergents (and it was recommended to try pancreatin else on the forum) for remove some of the very stubborn gums (Austria and some of the early GB QV's come to mind)

As used stamps such as yours were originally on  envelopes, they would seem to be soak-able in water (or surely someone by now would have loudly warned against!)

Scott U.S. #2

Had to get it because of the Fall River postmark or is it a receiving mark? What kind of cancel is on the stamp?

I, too, am suspicious, but I liked the look of the cover. The seller is in Bavaria, Germany and there were other bidders. I won at $241.43 converted from GBP 205. 

I have a loose #2, but it has only 3 margins. This has 4. At worst, I soak it off the cover and replace the one in my album.
