500 Kroner 'Plovmand' Heilmann type I

Heilmann's "Plovmand" (Plowman) series marked a deliberate shift in Danish banknote design — away from the heavily allegorical Continental style toward something more grounded in Danish rural identity. Heilmann was primarily known as an ornithologist and scientific illustrator, an unusual background for a banknote designer, and his draftsmanship shows it: the engraving has a naturalist's precision rather than the decorative softness typical of the period's commercial note work.

The Type I designation distinguishes early printings within the series run, which extended across a volatile stretch that included the disruptions of the First World War and Denmark's 1914 suspension of gold convertibility. At the 500-krone denomination, these circulated in relatively small numbers and saw hard use in wholesale and banking transactions rather than everyday commerce.
