A few months ago I opened a letter that came to me and cut out the stamp to keep. I later realized, upon closer examination, that the stamp was a misprint or freak. Of course, now I wish I had kept the entire envelope :-)
Scott #4963 (A3816) USA Stars and Stripes issue for 2015.
I have done some research and can't find any other issues with this mistake. Anyone have any ideas? Is it rare?
The photo below shows the misprint on the bottom left and the other 3 stamps are the originals in the series.
