Understanding Key Identification Factors
Identifying a stamp correctly requires careful examination of several key characteristics. While the Stamp Identifier App can automate this process, understanding these factors will help you become a more knowledgeable collector.
Country of Origin
Most stamps include the country name or a symbol representing the issuing nation. Some older stamps, particularly those from the United Kingdom, may not show the country name but instead feature the monarch's profile.

Perforations
The pattern of small holes around a stamp's edges is called perforation. Different countries and time periods used different perforation patterns and sizes. Perforation gauge tools can help measure these precisely.

Watermarks
Many stamps have watermarks embedded in the paper as a security feature. These can be crucial for identifying specific issues and varieties. Watermarks are often visible when the stamp is placed in watermark fluid or a black tray.

Step-by-Step Identification Process
Examine the Stamp Carefully
Look for country name, denomination, and any identifying text or symbols. Use a magnifying glass to see small details.
Check Perforations
Use a perforation gauge to measure the number of perforations per 2 centimeters. This can help narrow down the specific issue.
Look for Watermarks
Place the stamp in a black tray or use watermark fluid to reveal any hidden watermarks in the paper.
Use the Stamp Identifier App
Utilize the app to quickly identify and catalog your stamps based on their visual characteristics.
Stamp Valuation
Understanding what makes stamps valuable
Factors Affecting Stamp Value
The value of a stamp is determined by several key factors. Understanding these can help you assess your collection and make informed decisions when buying or selling stamps.
Rarity
The scarcity of a stamp is perhaps the most significant factor in determining its value. Stamps with limited printing runs or those that were mostly used and discarded tend to be more valuable.

Condition
The physical condition of a stamp dramatically affects its value. Mint condition stamps (never used, with original gum) typically command the highest prices, while damaged stamps may be worth only a fraction of their potential value.

Age
While age alone doesn't determine value, older stamps tend to be rarer and thus more valuable. However, a common stamp from the 19th century might be worth less than a rare stamp from the 1950s.

Errors and Varieties
Stamps with printing errors, color variations, or other production anomalies often command premium prices. These "mistakes" make the stamps unique and highly sought after by collectors.

Demand
The number of collectors interested in a particular stamp or type of stamp significantly affects its market value. Popular themes like wildlife, space exploration, or famous historical figures often command higher prices.

How to Value Your Stamps
Identify the Stamp Correctly
Accurate identification is essential for valuation. Use the Stamp Identifier App or consult a comprehensive catalog.
Assess the Condition
Carefully examine your stamp for any flaws, including tears, thin spots, creases, or fading. The better the condition, the higher the value.
Check Recent Sales
Look at recent auction results or dealer listings for similar stamps to get an idea of current market value.
Consult Multiple Sources
Don't rely on a single source for valuation. Check multiple catalogs, auction sites, and dealer listings to get a comprehensive view of your stamp's value.
Consider Professional Appraisal
For potentially valuable stamps, consider getting a professional appraisal or certification from a recognized authority.

Preserving Stamp Condition
Maintaining the condition of your stamps is crucial for preserving their value. Here are some tips to help you keep your collection in top shape.
Avoid Direct Sunlight
Exposure to sunlight can cause stamps to fade and lose their color. Store your collection in a cool, dark place.

Handle with Care
Always use stamp tongs to handle your stamps. This prevents oils and dirt from your fingers from damaging the paper.

Store Properly
Use archival-quality albums and storage materials to protect your stamps from environmental damage.

How to Preserve Stamp Condition
Use Protective Covers
Place each stamp in a protective cover or sleeve to prevent damage from handling and environmental factors.
Avoid Humidity
Humidity can cause stamps to stick together or develop mold. Keep your collection in a dry environment.
Regular Inspections
Periodically inspect your collection for signs of damage or deterioration and take corrective action as needed.
Consult Experts
If you are unsure about the best way to preserve a particular stamp, consult with a philatelic expert or conservator.
