All First-Class Stamps to Be Marked 'Forever' Say goodbye to first-class stamps marked with postage values By Mark Russell, Newser Staff Posted Dec 29, 2010 4:34 AM CST 2 comments Comments The new US Postal Service stamps will all show "forever", instead of a specific value. (AP Photo/USPS) (Newser) – No more struggling with one-cent stamps every time the Post Office raises the price of mailing a letter. Beginning in January, all stamps for 1-ounce, first-class mail will simply be marked "forever." Forever Stamps were first issued in 2007 and designed for use regardless of changes in postal rates; so far the Postal Service has sold $12.1 billion worth, accounting for 85% of its stamps. But now, all stamps will be without a printed denomination. The Postal Service unveiled the commemorative stamps for 2011 yesterday, all marked "forever," reports AP. The first stamp with the new label will be a Year of the Rabbit stamp, issued Jan. 22, followed by Kansas on Jan. 29, and one for the centenary of Ronald Reagan's birth in February. The new policy is expected to be announced officially on Jan. 14.
