The U.S. Postal Service has announced that the price of a first-class stamp will increase to 44 cents, starting May 11, 2009. The new postage is for the first ounce of a First-Class mail – the most common type for mailing letters, payment checks, etc.
The forever stamps will continue to be sold at 42 cents, until the price increase occurs in May. These stamps can be used “forever,” meaning that regardless of when you purchased them, or how much you paid for them, they are always good for mailing one-ounce letters. There is currently only one type of forever stamp, introduced in 2007. See the image on the right.
Keep in mind that those Nondenominated Stamps – stamps without showing their price – are not forever stamps. They have different values and styles. For example, the popular American Flag stamp, which shows “USA First-Class” on the face but no dollar value, is actually 41-cent each. Starting May 11, you will need additional 3 cents of postage in order to use the flag stamp for a first-class mail.
A stamp with its price printed is always worth what its face value indicates, obviously.
