To mail a 9.3 oz letter within the United States, you would typically need to use a combination of stamps that cover the postage for the weight. As of my last update, the first ounce costs a certain amount, and each additional ounce incurs an extra fee. You would need to check the current postage rates from the USPS to calculate the exact number of stamps needed, as rates can change. Generally, you might need around 3-4 standard Forever stamps, depending on the total postage required.
