History of U.S. Postage Stamp Prices

Prior to the middle of the 19th century, rates were based on the number of sheets in a letter and the distance it was traveling. In 1845, rates were based on the weight of a letter and the distance it was going. Beginning in 1863, domestic letter rates became "uniform," that is, they were based solely on weight, regardless of distance.

Postage listed below is in cents.

Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer.
