Understanding Gum and Its Condition
Gum condition is a critical factor in determining the value of stamps. The adhesive on the back of a stamp when it was first issued is known as the original gum. Stamps in “mint, never hinged” condition have undisturbed original gum, which is highly desirable among collectors. However, regummed stamps can also be found in the market, where additional gum or gum repairs have been applied.
Regumming is often used to conceal defects like tears, thin spots, or repairs, making it important for collectors to be familiar with the characteristics of original gum for specific stamp issues. By understanding the attributes of original gum, collectors can better detect alterations and ensure the authenticity of their stamps.
Changes in Gum Due to Regumming
Regumming stamps can bring about noticeable changes in the appearance and characteristics of the gum. When old hinge remnants are carefully removed, the stamp is placed in a damp environment to liquefy the original gum. This allows the remaining gum to be redistributed, effectively hiding any previous hinge traces. However, the drying process and subsequent brushing can cause the gum to become thinner, resulting in alterations to its thickness and overall appearance. In some cases, regummed stamps may exhibit bubbles or cracks if the gum has not been properly dried. Additionally, certain gum alteration methods, such as spraying, can leave behind distinguishing marks.
Regumming stamps can lead to changes in the gum’s appearance and characteristics.
| Gum Alteration | Potential Effects |
|---|---|
| Redistributed Original Gum | The remaining gum is moved to hide previous hinge traces. |
| Thinner Gum | The drying process and brushing can result in the gum becoming thinner. |
| Bubbles or Cracks | Improper drying may cause regummed stamps to exhibit bubbles or cracks in the gum. |
| Gum Alteration Methods | Methods like spraying can leave behind characteristic marks on the gum. |
Detecting Regummed Stamps and Hidden Faults
Detecting regummed stamps can be quite challenging, as they often display similar characteristics to stamps with redistributed original gum. Regummed stamps are frequently used as a means to conceal hidden faults, such as tears, thin spots, or repairs. The addition of new gum can effectively mask these issues, making them difficult to identify solely through the appearance of the gum itself. Detecting thin spots can pose an even greater challenge, as they may be filled with foreign substances and covered with new gum to create the illusion of a flawless stamp.
To identify regummed stamps and hidden faults, collectors can employ a helpful strategy: comparing stamps with fresh original gum to serve as a control copy. By carefully examining both the control copy and the stamp in question, they can identify any discrepancies that may indicate regumming or the presence of hidden faults.
By paying attention to details and using their expertise, collectors can uncover regummed stamps and hidden faults that would otherwise be elusive. This diligence ensures the integrity of their stamp collections and preserves the historical value of these philatelic treasures.
