Re: what's the difference between a 1932 3 cent washington perforated 10V and one that's perforated
The stamps you are asking about are from coils rather than sheets. They only have perforations (holes) along two sides, instead of all four sides as would a stamp from a sheet. The H stands for horizontal which means the holes run along the top and bottom. The V stands for vertical which means the holes run up and down the sides.
