The U.S. Postal Service had available for sale in March 2021 the following 65-cent fundraising or “semipostal” stamps: the congressionally mandated Breast Cancer Research stamp and Save Vanishing Species stamp as well as the U.S. Postal Service’s discretionary Alzheimer’s stamp and Healing PTSD stamp. These stamps were available for purchase at Post Offices™, online at The Postal Store®, and by toll-free phone order at 1-800-782-6724.
The price of a semipostal stamp pays for the First-Class single-piece postage rate in effect at the time of purchase plus an amount to fund causes that have been determined to be in the national public interest. By law, revenue from sales (minus postage and the reasonable reimbursement of costs to the Postal Service™) is to be transferred to a selected executive agency or agencies.
