The stamps of these sovereign Indian nations allow holders to hunt on that reservation when a federal stamp is also purchased. Reservation stamps are becoming increasingly popular with collectors as more people discover their existence. Errors With the printing of such a large number of stamps year after year by many different states and printing agencies, errors do occur, but are seldom found. Stamps without perforations, with missing or incorrect color, missing or inverted writing on the reverse are all major errors.

All errors and freaks on duck stamps are very desirable and add a great deal of interest and value to a collection. How to collect duck stamps The first basic rule is to remember that stamp collecting is very personal. Most collectors prefer to collect mint condition duck stamps. Many others prefer collecting stamps on license, autographed stamps, plate blocks, stamps signed by hunters, art prints, souvenir cards, first day covers, or a combination. The bottom line, however, is to collect what interests you.
