Philately – selling of postage stamps
How to Start Collecting Postage Stamps and Turn This Hobby into a Smart Investment
When the first postage stamps appeared in the mid-19th century, no one imagined they would become such a fascinating collectible. Today, more than 180 years later, stamps are collected by celebrities, royalty, and investors alike. Why is philately so captivating? Let’s explore the world of perforated beauty together.
What Is Philately?
Philately is the study of postage stamps and postal history. It includes not only stamps themselves but also postal stationery, covers, cancellations, and postal labels. Stamp collecting began in Great Britain—the birthplace of the first postage stamp—and spread across Europe and the world around 1860.

In Slovakia, the beginnings of organized philately date back to 1895, when the first philatelic club ALBUM was founded in Kremnica.
How Stamp Values Are Determined
The value of a collection is not only about money. For most philatelists, the main motivation is joy, knowledge, and community. Still, there are three basic types of value:
- catalog value,
- market value,
- collector value.
Catalog Value
Catalog value is based on information published in philatelic catalogs. It is an important reference point, but it does not always match real market prices. Catalogs reflect the experience and perspective of their publishers, so prices may vary.

- Zagorsky – Imperial Russia, USSR
- Michel – Germany, Switzerland
- Stanley Gibbons – Great Britain, Commonwealth
- Pofis – Czechoslovakia, Czech Republic
Market Value
Market value best reflects the real price. It usually represents 20–30% of catalog value. Auction catalogs and realized auction prices are helpful for estimating it.
Collector Value
This depends on how popular a stamp is among collectors. It can rise or fall quickly depending on trends, the appearance of forgeries, or the sudden discovery of larger quantities of material.
Where to Buy Philatelic Material
Today, you don’t need to visit only POFIS or physical shops. You can also buy stamps through:
- online stores,
- philatelic fairs,
- collector exhibitions (e.g., Zberateľ in Bratislava and Prague),
- subscriptions of new issues directly from postal authorities.
