Postage stamp. Additional Ounce Forever Stamp

Uncle Sam’s Hat Additional Ounce Stamp is a non-denominated U.S. postage stamp issued by the U.S. Postal Service that remains permanently valid to cover the current additional-ounce rate for First-Class Mail. Roll of 100 stamps. New. Unopened. I have a few rolls. $29 per roll at USPS. Key Details Design: Features eight graphic top hats with red and white vertical stripes, a blue band with a white star, a gray brim, and diverse oval face shapes underneath. Function: Used alongside a standard Forever stamp to mail heavier letters, wedding invitations, or square envelopes that exceed the standard one-ounce weight limit. Validity: Like Forever stamps, these "Additional Ounce" stamps never expire and hold a face value equal to the current domestic additional ounce rate regardless of when you bought them or how postal rates change.
