The Challenge of Managing Duplicate Stamps
Every active stamp collector eventually faces the pleasant problem of accumulating duplicate stamps. Whether you acquire stamps through bulk mixtures, kiloware, or inherited collections, you will often find yourself with multiple copies of the exact same issue. Managing these duplicates is a fundamental skill in philatelic preservation. Instead of letting them pile up unsorted, a systematic approach allows you to select the highest-quality specimen for your primary collection while keeping the remaining copies in pristine condition for future trading or specialized study.
Evaluating and Selecting the Best Copy
When faced with several copies of the same stamp, your first task is to evaluate them systematically to choose the best one for your album. Look for stamps that are well-centered, meaning the design is evenly positioned within the perforated borders. Next, examine the cancellation marks on used stamps; a lightly canceled copy that does not obscure the central design is generally preferred over a heavily inked or smeared cancellation. Use a magnifying glass with 5x to 10x magnification to inspect the fine details and check for hidden flaws. During this sorting process, you should remove any badly damaged stamps, such as those with heavy tears or missing corners, unless the stamp is exceptionally valuable or difficult to replace.
Safe Handling Tools for Loose and Dry Stamps
Preservation begins with how you handle your stamps during the sorting process. No matter how thoroughly you wash your hands, natural oils from your skin will transfer to the paper and cause gradual damage over time. To prevent this, always use professional stamp tongs to handle dry stamps. Tongs resemble tweezers but feature a smooth gripping surface specifically designed to avoid crimping or tearing delicate paper. However, a critical distinction must be made between wet and dry stamps: while tongs are indispensable for dry stamps, you must exercise extreme caution if you use them on wet stamps. Wet paper is significantly weaker and more easily damaged, so it is often safest to let soaked stamps dry completely on paper towels under a light weight before attempting to sort or handle them extensively.
Temporary Storage in Glassine Envelopes
Once you have sorted your duplicates, you need a safe environment to store them before they are traded or mounted. Glassine envelopes are the industry standard for temporary storage. These semi-translucent, grease-resistant paper envelopes protect stamps from dust, light handling, and environmental moisture. When placing your duplicates in glassine envelopes, never use tape or glue to seal the envelopes or secure the stamps inside. Adhesives will permanently decrease a stamp's value and cause severe damage when you eventually try to remove them. Instead, keep the stamps loose inside the glassine, grouping them by country or topic until you are ready to transfer them.
Organizing Duplicates in Stock Books
For larger quantities of duplicates, a stock book is an exceptionally practical tool. Unlike a traditional stamp album, which features printed pictures of specific stamps on designated pages, a stock book contains blank pages fitted with horizontal plastic or paper pockets. This design allows you to organize your stamps however you wish, making it easy to slide duplicates in and out as your inventory changes. Stock books keep your stamps flat and protected while allowing you to view multiple copies side-by-side for comparison. Using a digital tool like StampSnap can assist you in identifying the exact varieties of your duplicates before you slide them into their designated rows.
Preparing Duplicates for Trading and Future Use
The final step in managing your duplicates is organizing them by a consistent system so they are ready for trading or specialized study. You can sort your duplicates by country of origin, thematic topic, or by the specific service the stamp was intended to provide, such as airmail, special delivery, postage due, parcel post, or revenue stamps. If you encounter a stamp without a country name, remember that Great Britain is the only nation permitted to omit its name, using the ruling monarch's image instead. For other challenging look-alikes, StampSnap can help you identify the issuing country. Keeping your duplicates neatly categorized in glassines or stock books ensures they remain in collectible condition, ready to be shared with other collectors.
Frequently asked questions
How do I choose which duplicate stamp to keep for my album?
Select the copy that is well-centered with even borders and features a light, clean cancellation mark that does not obscure the design. Avoid keeping badly damaged copies unless they are rare and difficult to replace.
Can I use regular tweezers to handle my duplicate stamps?
No, regular tweezers often have ridged or sharp tips that can puncture, crimp, or tear delicate stamp paper. Always use professional stamp tongs, which feature a smooth gripping surface designed specifically for safe philatelic handling.
What is the safest way to store duplicate stamps before trading them?
Store your loose duplicates in glassine envelopes or stock books with plastic or paper pockets. Never use tape, glue, or sticky photo albums, as these adhesives will permanently damage the stamps and decrease their value.
How should I sort my duplicate stamps to make trading easier?
You can organize your duplicates by country, thematic topic, or by the service they provided, such as airmail, special delivery, postage due, parcel post, or revenue stamps.
