About 10 states issue two types of stamps, one for collectors and another for hunter use. Collector stamps are usually in panes of 10 or 30 without tabs. Hunter type stamps are usually issued in panes of five or 10, many with tabs attached. Hunters use the tabs to list their name, address, age and other data. Some states use only serial numbers to designate their hunter type stamp. State stamps are therefore referred to as either collector stamps or hunter type stamps. Most dealers will distinguish between these types on their price lists. Separate albums exist for both types and are available from most dealers.

Plate blocks or control number blocks are designations given to a block of stamps, usually four, with a plate or control number present on the selvage. Such a block is usually located in one or all four corners of a pane. Federal stamps prior to 1959 plus the 1964 issue are collected in blocks of six and must have the selvage on two sides. The Federal Junior Duck Stamp Program is a non-profit program sponsored by the Federal Government and designed to promote interest in conservation and wetlands preservation among students in grades K to 12. The program includes a conservation and education curriculum that helps students of all ages. It focuses on wildlife conservation and management, wildlife art and philately. All proceeds from sales support conservation education.

Governor's editions have been issued by several state agencies as a means of raising additional income. These stamps are printed in small quantities, most fewer than 1,000. They have a face value of approximately $50, and are imprinted with the name of the state governor. Governors also hand-sign a limited number of stamps. These are usually available at a premium, generally twice the price of normal singles. Hand-signed or autographed stamps are issued in very small quantities and are scarce to rare. Governor's editions are valid for hunting by all issuing states, but none would be used for that purpose, however, as it would destroy the mint condition and lower the value of the stamp.
