The U.S. Postal Service Act of February 1925 provided for a 25¢ fee that allowed fourth-class mail to receive the same service as first-class. On April 11, 1925, a 25¢ special handling stamp was issued. When added to an item that carried regular fourth-class postage, this stamp allowed the item to be handled as first-class matter. Three years later, 10¢, 15¢, and 20¢ denominations were issued to cover the revised rates that went into effect in July 1928.
