The breast cancer research stamp (BCRS) is a semi-postal non-denominated postage stamp issued by the United States Postal Service, priced in 2011 as eleven cents higher than the standard first-class letter rate. The surplus above the price of the first-class stamp is collected by the United States Postal Service (USPS) and allocated to the National Institutes of Health (NIH) and the Department of Defense (DoD) for breast cancer research. If a person used this stamp exclusively, and mailed one letter per day for a year, the resulting donation would amount to US $40.
