50 Øre - Olav V Trial strike

Trial strikes from Den Kongelige Mynt are rarely documented in public literature, and this 1970 piece predates the actual 50 øre Olav V copper-nickel issue that entered circulation in 1971. It almost certainly represents an internal production test — verifying die alignment, alloy behaviour, or striking pressure — rather than any official proof or presentation piece. The distinction matters for attribution.
