The Challenge of Look-Alike Definitives
Identifying postage stamps accurately in a worldwide catalog can be a complex task, much like finding a specific seat in an unfamiliar sports stadium. While knowing the issuing nation gets you to the right country section, and identifying the basic design gets you to the correct general listing, the real challenge lies in distinguishing look-alike definitives. These stamps are often printed over decades with only minor changes in design, color, or text, which can easily frustrate even patient philatelists.
To value these stamps correctly, collectors must pay close attention to detail and maintain a relentless curiosity. A stamp that appears identical to a common, low-value definitive at first glance might actually be a scarcer commemorative issue. By learning how to spot subtle variations, such as year-dates added to the corners of a design, you can determine the correct catalog number and understand its true place in your collection.
The Impact of Corner Date Inscriptions on Value
A prime example of how small design changes alter a stamp's identity and value can be found in the early issues of Liechtenstein, released under Austrian administration between 1912 and 1918. Among these are eleven stamps featuring the profile of Prince Johann II. The 1917 to 1918 20-heller dark green stamp was a standard definitive. However, on November 12, 1918, a very similar stamp was released to commemorate the 60th anniversary of the Prince's accession.
This commemorative version replaced the original upper corner designs with the specific year-dates of his reign. Because these dates are extremely small and difficult to see, standard catalogs like the Scott catalog include boldface notes such as Dates in Upper Corners to guide collectors. Distinguishing between the standard definitive and the commemorative version is essential, as they have different catalog numbers and distinct values based on their scarcity and historical purpose.
Distinguishing Purpose-Specific Inscriptions
Similar stamps frequently serve entirely different purposes, and these purposes are often indicated by subtle text changes. For instance, the 1886 half-cent North Borneo stamp features a design that pays postage only, displaying the word POSTAGE near the bottom. In contrast, the 1887 version of the same half-cent rose stamp was updated to pay both postage and revenue fees, displaying POSTAGE & REVENUE on a scroll that spreads to the edge of the design.
Newcomers to collecting North Borneo or Liechtenstein may easily miss these differences if they do not perform a close visual inspection. When you encounter look-alike stamps, using a tool like StampSnap can help you create a digital record of your specimen and suggest a likely identification. However, because physical condition and microscopic details vary, visual tools should be paired with systematic manual checks to confirm the exact variety.
A Methodical Process for Close Inspection
To safely examine your stamps for tiny corner inscriptions or text variations, you must follow a careful, step-by-step process. Always handle your stamps with professional philatelic tongs to prevent transferring oils or moisture from your fingers. Place the stamp on a clean, flat, and dark surface under a strong, glare-free light source.
Use a high-quality magnifying glass or a digital magnifier to inspect the upper and lower corners of the design. Compare the details directly with the illustrations and boldface notes in a reputable worldwide catalog. Look specifically for numbers, dates, or altered scrollwork that might indicate a commemorative or dual-purpose issue rather than a standard definitive.
Verifying Paper and Watermark Variations
If the design elements and corner inscriptions appear identical, the difference in catalog number and value may lie in the paper itself. Many stamps with identical designs exist on both watermarked and unwatermarked paper, or on paper with different watermark designs. These watermarks are security measures made of words, letters, or symbols formed during paper manufacturing, resulting in thin places in the paper pulp.
To safely check for watermarks, lay the stamp face down in a dark tray and moisten it with a safe, commercial watermark fluid, such as Clarity fluid. This fluid evaporates quickly and will not damage the gum on an unused stamp. The watermark will appear as dark lines against a lighter background, helping you distinguish between different watermark types, such as the single-line or double-line USPS watermarks used on classic United States stamps.
Documenting Your Findings Safely
Once you have identified the specific corner inscriptions, text variations, or watermarks, you can document your findings. You can use StampSnap to organize your collection, log the specific variety, and keep track of your notes. Remember that estimated values found in catalogs or digital tools are purely informational and highly dependent on the stamp's physical condition, such as the presence of thins, creases, or cancellation marks.
Never attempt to alter a stamp, remove it from a cover using household solvents, or use tape or glue on your philatelic material. If you are uncertain about a highly valuable variety, consider seeking an opinion from an expertizing service. By maintaining a methodical approach and paying attention to the smallest details, you can safely build and value your collection.
Frequently asked questions
How do corner dates affect the value of look-alike stamps?
Corner dates often distinguish a standard definitive stamp from a commemorative edition. For example, Liechtenstein's 1918 Prince Johann II stamp added accession dates to the upper corners of the 1917 definitive design, resulting in a different catalog number and value.
What is the difference between postage and postage and revenue stamps?
Some look-alike stamps have subtle text changes indicating their purpose. For instance, the 1886 North Borneo half-cent stamp displays POSTAGE at the bottom, while the 1887 version displays POSTAGE & REVENUE on a scroll, indicating it paid both types of fees.
How can I safely check for watermarks to value my stamps?
Lay the stamp face down in a dark tray and moisten it with a commercial watermark fluid. This safe fluid evaporates quickly without damaging the gum, revealing the watermark as dark lines against a lighter background.
Can a digital app officially appraise my stamp's value?
No, digital tools like StampSnap can help you identify likely stamp varieties and organize your collection, but they do not provide official appraisals or authentication. Estimated values are informational and highly dependent on physical condition.
