Danish perfin stamps - security patterns collection (PERForated INitial)

Danish perfins are postage stamps that have been perforated with initials, symbols or company marks to prevent theft and misuse. These punched patterns were used by businesses, banks, government offices and institutions throughout Denmark from the late 19th century into the mid-20th century. Each pattern identifies the organisation that owned and used the stamps, making perfins an important part of Denmark’s postal and commercial history.

This collection features a variety of Danish perfins across different reigns, printings and denominations. The punched initials often reflect well-known Danish companies, ministries and regional offices, offering a fascinating look into historical business activity. Collectors value Danish perfins for their clear patterns, wide variety of designs and the interesting research possibilities behind each code.

The stamps shown here include both common and scarcer patterns, presented to highlight the diversity of Danish perfin usage. This archive serves as a useful reference for anyone interested in Scandinavian philately or the study of security-marked postage.
