20 Ducats - Aureus Magnus Pope Pius XII

This piece was struck by a West German private mint for export and devotional sale, not as an official federal issue — the "Aureus Magnus" series occupied a grey zone between commemorative medal and coin that its producers exploited aggressively in the late 1950s. Pius XII died in October 1958, and pieces bearing his image flooded Catholic markets across Europe and Latin America in the months following his death.

The .980 fineness is notably purer than contemporary sovereign gold coinage, a deliberate selling point aimed at buyers treating these as bullion-adjacent devotional objects rather than numismatic pieces.
