A fund-raising card for encouraging sponsoring of charity organizations. The card is inscribed with a plurality or squares disposed in horizontal rows in vertical columns. Each square includes a printed numerical data expressed in dollars and cents. A removable layer of opaque material hides the money amounts and is removable by scratching. Random selection and uncovering of a desired number of money amounts and summation of the amounts of money so uncovered constitutes the randomly-chosen voluntary amount of donation for each donator to the charity organization.
