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.
Quality is a very important factor in a stamp collection.
This applies not only to duck stamps, but all types. Preserving the mint condition of a stamp is crucial for determining value. A perfectly centered stamp will usually sell for a substantial premium over one with normal centering. Care should be taken not to damage a stamp, including the gum. The mint state of a stamp includes the freshness and original gum, so stamp mounts should be utilized when placing a stamp in your album.
