Handelshaus Christoph Gärtner

Christoph Gärtner successfully laid the foundation stone of the C.G. Collectors World brand over 35 years ago with the founding of Handelshaus Gärtner. Newly-minted holder of a high-school diploma, the enthusiastic stamp collector founded his first company in 1984 and started buying and selling stamps. In just about 16 years, Gärtner was firmly established as a leading mail-order house for postal stationery as well as an expert on thematics and worldwide postal history.

Today, as an international marketplace for wholesale and retail trade, the company offers an impressive spectrum comprising national and international philately, numismatics, banknotes, and literature. Since Gärtner has always placed an emphasis on the brokerage of private sales, the “Private Treaty” sector has become increasingly diverse. Customers across the world now appreciate C.G.’s expert advice and liaising on the subject of exquisite “Valuable Collectables” from every field imaginable.
