Which of the following stamps is specifically created for charitable contributions?

Semi-Postal Stamps are specifically created for charitable contributions, making them a unique category within postage stamps. The revenue generated from the sale of these stamps is allocated to specific causes or charitable organizations, thus facilitating direct support for various initiatives, such as health campaigns or disaster relief efforts. These stamps are identified by a design that typically includes a marking indicating their purpose for charity.

In contrast, postage stamps are primarily designed to pay for mailing services, while revenue stamps are used to indicate the payment of taxes or fees, not contributions. Commemorative stamps celebrate significant events or individuals but do not directly fund charities. Semi-Postal Stamps uniquely serve the dual purpose of postage and philanthropy, reinforcing their distinctive role in supporting charitable causes.
