25 Øre Den Kongelige Grønlandske Handel. Type I: Perforated edge

Den Kongelige Grønlandske Handel operated as a Danish state monopoly controlling all commerce in Greenland, and the notes it issued were not legal tender in any conventional sense — they were scrip, valid only within the company's own trading posts. The 1911 series replaced an earlier generation of tokens and cardboard coupons, a reflection of growing settlement populations along the west coast who needed a more durable medium for everyday transactions within the monopoly system.

The Type I perforation along the edge was a security measure against counterfeiting and unauthorized reproduction, though in a closed trading monopoly with no competing currency, the practical threat was limited. It also served to distinguish this emission from later Type II unperforated stock.
