Collecting postcards can be a rewarding hobby, offering a glimpse into history through beautiful imagery and personal messages. Mary L. Martin Ltd. specializes in buying and selling these historical treasures, and we’re here to help you understand what makes a postcard truly valuable.
Look at the Age and Era

The age of a postcard is a primary factor in its value. Old postcards from the “Golden Age” of postcards (1907-1915) are often highly sought after due to their detailed lithography and divided backs for both messages and addresses. Early undivided-back postcards (pre-1907) and those from the Pioneer Era (before 1898) can also be quite valuable.
Check the Postcard’s Condition

A postcard’s condition is crucial. A card in excellent condition—with crisp corners, no creases, tears, or fading—will fetch a higher price than one that’s worn or damaged. Even a rare card will be worth less if it’s in poor shape.
Consider the Subject Matter and Rarity

The image on the postcard is a major determinant of its value. Popular and rare subjects, such as historic events, unique landmarks, or specific artist-drawn cards, can be very valuable. National park postcards, for example, are highly collectible, especially early ones that show what the parks were like a century ago. A postcard that is one-of-a-kind or part of a very limited print run is also extremely valuable.
Examine Postmarks and Stamps

A postmark and stamp can add to a postcard’s value, particularly if they are rare or unique. Collectors look for unique cancellations, special event stamps, or early postmarks. A clear, legible postmark from a small town or one that dates back to the very early days of postcard mailing can increase its desirability.
The value of a postcard is determined by a combination of factors. By carefully examining its age, condition, subject, and postal history, you can better understand its worth. Whether you’re an experienced deltiologist or a casual collector, knowing these tips can help you uncover the true value of the vintage postcard treasures in your collection.
