It depends on the size of the stamp, and when it was issued, 100 1936 presidential series weigh about 6 grams, it takes about 8000 of these stamps to weigh 1 pound.

80 groups of these stamps would weight about 480 grams {80 * 6} = 480 grams, which is a little more than a pound. 454 grams = 1 pound. The 1950's series weigh a little more, it takes about 6000 of these to weigh about a pound.
