How to Find the Value of a Stamp: 20 DIY Tips

Check the condition of the stamp corners

● Introduction: The condition of the corners of a stamp affects its value, as collectors prefer stamps with perfect or centered corners.
● NOTE: Inspecting the corners is helpful in assessing the stamp for any damage, such as bent corners or creases, which could affect the stamp’s overall condition and desirability.
● Operating steps: Put the stamp under good light and check every corner carefully. Look for any signs of bends, creases, or damage. Ideally, all four corners should be sharp and intact.

Evaluate the glue or adhesive of the stamp

● Introduction: The quality and condition of the gum or binder of a stamp affects its value, especially if it is unused or new.
● Description: Collectors prefer stamps with pristine, undisturbed gum that has not been damaged or discolored.
● Operating steps: Carefully check the back of the stamp where there is glue or adhesive. Look for any interference, discoloration, tint or missing gums. Stamps with intact, clean backing are usually more valuable.

Consider the centering of the stamp

● Introduction: Centering of a stamp refers to the positioning of the stamp within the edge of the perforation or within the boundaries of the design.
● Explanation: Stamps with beautiful central designs are usually more popular with collectors.
● Operation steps: Observe the design and perforation of the stamp. Check that the design is symmetrical and that the margins are equal on all sides. Stamps with centered designs are usually worth more.

Assess for the presence of the watermark

● Introduction: Some postage stamps feature a watermark, which is a subtle design or pattern embedded in the paper.

● How to do it: Hold the stamp up to the light or use the watermark detector to reveal any hidden watermarks. Identify and study the importance of watermarks to the value of postage stamps.

Make a note of any cancellation flags

● Operating steps: Check whether there are any traces of cancellation on the stamp surface. Assess the clarity, visibility and impact of the cancellation on the stamp. Depending on collecting preferences, cancellation marks can increase or decrease the value of a stamp.

Check the piercing type

● Introduction: Perforations are small holes or perforations in the edges of stamps for easy separation.
● Note: Some stamps have different perforation sizes or patterns, which can make them more valuable to collectors.
● Operation steps: Check the perforation of the stamp with a perforation gauge or ruler. Compare the measurements to known standards for that stamp problem. Variations in piercings can indicate a rare or unique breed.

Determine the age and historical significance of stamps
