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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. 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. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
