2023 Toni Morrison forever stamps

Forever Stamps are non-denominated First-Class postage, meaning they can be used to mail First-Class letters regardless of future rate increases. For example, in 2013, the cost to send a standard one-ounce letter within the United States was $0.46. The rate rose to $0.49 in 2014. Customers who purchased Forever Stamps at the 2013 rate can still use them today without adding extra postage. Currently, the price of a Forever Stamp is $0.63, but its value will always cover the prevailing First-Class letter rate.
