The Golden Rule of Stamp Handling: Dry vs. Wet States
Preserving a postage stamp requires a clear understanding of its physical state. Dry stamps and wet stamps demand entirely different handling protocols to prevent permanent damage. For dry stamps, the primary threat is the natural oil from human skin, which can cause long-term degradation. To protect dry stamps, collectors should handle them as little as possible and always use specialized stamp tongs. Conversely, wet stamps—such as those undergoing a soaking process—are highly fragile and exceptionally prone to tearing. While some general guides suggest using tongs with extreme care on wet paper, the safest preservation practice is to avoid using tongs on wet stamps entirely. Instead, allow them to float free and dry completely before attempting to handle them with tools.
Safely Managing Dry Stamps with Tongs and Magnifiers
When working with dry philatelic material, specialized tools are essential for maintaining condition. Stamp tongs, which resemble tweezers but feature a smooth gripping surface, are designed specifically to handle stamps without leaving marks or transferring skin oils. To inspect fine details without physical contact, a magnifying glass with 5x to 10x magnification is highly recommended. Selecting a magnifier that folds into a protective case helps prevent scratches on the lens. By using a magnifier alongside the StampSnap app, collectors can inspect fine details and create a likely identification record without subjecting the fragile paper to unnecessary physical handling.
The Soaking Process: When and How to Wet Stamps Safely
Removing stamps from paper envelopes is a common task, but it must be performed with extreme care. To begin, cut the upper right-hand corner of the envelope, taking care not to cut the stamp itself. Brightly colored envelopes, such as red or green covers, must be set aside and soaked separately because their dyes may bleed and stain the stamp paper. Place the paper clippings stamp-side up in a bowl containing a few inches of lukewarm water. Never use hot water, as it can damage the paper and design. Ensure the stamps have enough room to float freely, and change the water after processing two or three batches. Note that while most older self-adhesive stamps can be soaked, many United States self-adhesives issued in 2004 or later feature an oil-based backing rather than a water-based one, meaning they will not soak off in water and require specialized oil solvents.
Handling Wet Stamps and the Drying Phase
During the soaking process, patience is critical. As the stamps float in the lukewarm water, they will eventually begin to separate from the envelope paper. Never attempt to pull or peel a stamp free before it is fully ready, as this will likely result in a tear. Once the stamp has floated completely free, gently rinse the back of the stamp in fresh water to ensure all remaining gum is removed. Because wet paper is highly vulnerable, do not use tongs to lift or move the wet stamp. Instead, carefully transfer the wet stamps to a safe drying environment. Placing the stamps face down between two clean paper towels and placing a heavy book on top will help prevent curling as they dry overnight.
Sorting and Preparing Dry Stamps for Storage
Once your stamps are completely dry, they are safe to handle with tongs and can be prepared for sorting. Before mounting them, organize your stamps systematically. Depending on your collecting goals, you can sort them by country, topic, or the specific service they were meant to provide, such as airmail, special delivery, postage due, parcel post, or revenue stamps. During this sorting phase, inspect each specimen and remove badly damaged stamps, unless a copy is highly valuable and difficult to replace. If you have multiple copies of the same stamp, select the copy with the best centering and the lightest cancellation, keeping the duplicates in glassine envelopes for future trading.
Safe Long-Term Storage: Albums, Stock Books, and Mounts
For long-term preservation, store your dry stamps in albums or stock books. Stock books feature plastic or paper pockets on each page, allowing you to organize your stamps freely. If you choose a traditional stamp album, you can mount your stamps using peelable hinges or clear plastic mounts. Never use household tape or glue, as these adhesives will permanently damage the paper and drastically decrease the stamp's value. To use a stamp hinge, lightly moisten the shorter end of the folded translucent paper and press it to the back of the stamp, positioning the fold about 1/8 inch from the top. Then, lightly moisten the larger portion of the hinge to secure it to the album page. Once your dry stamps are safely mounted, you can use StampSnap to log your organized collection and keep a digital inventory of your preserved specimens.
Frequently asked questions
Can I use regular tweezers to handle my stamps?
No, you should avoid regular household tweezers because they often have ridged or sharp tips that can tear or crease fragile stamp paper. Instead, use specialized stamp tongs, which feature a smooth gripping surface designed specifically for safe handling.
Why should I avoid using tongs on wet stamps?
Wet stamp paper is highly fragile and loses its structural integrity. Using metal tongs on wet paper can easily cause punctures, tears, or scuffs. It is safest to let the stamps float free in water and dry completely before handling them with tongs.
How do I prevent my stamps from curling as they dry?
After gently rinsing the soaked stamps in fresh water, place them face down between two clean paper towels. Place a heavy book on top of the paper towels and leave them to dry overnight. This flat pressure prevents the paper from curling as the moisture evaporates.
Can all self-adhesive stamps be removed by soaking them in water?
No. While older self-adhesives can often be soaked off, many United States self-adhesive stamps issued in 2004 or later use an oil-based backing instead of a water-based one. These stamps will not release in water and require an oil solvent to separate them from paper.
