1 Krone - Margrethe II Pattern; type IVb; without hole

In 1986, the Danish Mint was actively trialing revised designs and physical specifications for the krone series — this piece is one of several documented pattern variants distinguished by the absence of the central hole that ultimately defined the issued circulation type. Pattern type IVb represents a late-stage trial; by this point in the process, the hole configuration had already become the expected outcome, making the solid-flan variant a deliberate rejection test rather than a genuine design contender.
