Lawrence stamp collectors or anyone who wants to save money later on postage will get a chance to buy the “forever” stamp today.

The stamp, which has an image of the Liberty Bell, will sell for 41 cents and will remain valid for first-class postage regardless of future rate increases.

In Lawrence and nationwide, forever stamps will be sold in booklets of 20.

The current 39-cent price for first-class mail will increase to 41 cents May 14, although forever stamps could be used earlier.

Postal officials, however, acknowledge that most people will save the new stamps for use the next time the postage price increases because of their infinite validity.

“I would anticipate, across the nation, people would buy a lot of (forever) stamps in bulk for that reason,” said Michael O. Behrend, manager of customer service at the Lawrence post office, 645 Vt.
