Classify Postage stamps
Determining postage stamps, also known as identifying or classifying stamps, is an important aspect of philately. It involves the process of accurately identifying a stamp based on various characteristics such as design, color, perforation, watermark, and printing techniques. Here is an overview of the steps and aspects involved in identifying stamps:
Steps in Determining Postage Stamps
Identifying the Country of Origin:
- Check the language, symbols, and other markings on the stamp to determine the country of origin.
Analysis of the Design and Images:
- Study the design, images, and texts on the stamp. Many stamps contain iconic images or texts that indicate their origin or period.
Determining the Nominal Value:
- Read the face value on the stamp. This can help identify the period and use of the stamp.
Examining the Perforation:
- Count the number of perforations per two centimeters (or per inch) to determine the perforation. This is referred to as the “perforation size”.Checking the Watermark:
- Many stamps have watermarks that can aid in identification. This can be done using a watermark detector or by holding the stamp up to the light.
Color and Ink Analysis:
- Compare stamp color to reference guides as colors may vary by issue and printing run.
Study printing technique:
- Identify the printing technique used (engraving, lithography, typography, etc.). This can often be viewed under a magnifying glass.
Reference to Catalogs:
- Use philatelic catalogs such as the Michel Catalog, Scott Catalog, Stanley Gibbons Catalog, or Yvert et Tellier Catalog to accurately identify and value the stamp.
