Duivenvoorde Castle, located near The Hague, was built in the 13^th century as a defense tower. Remnants of this tower can still be seen in the facade and the front house of the castle. Over the years, the castle's defensive function has virtually disappeared and the building has primarily been given a residential function. Gradually, many halls and wings have been added to the main structure. The castle has always been owned by families: it has never been sold, only acquired by inheritance. As a result, the castle has been home to the Van Wassenaer family (13^th-18^th century), the Steengracht family (19^th century) and finally the Schimmelpenninck Van Der Oye family (20^th century). In 1960 the last owner, Ludolphine Henriette Baroness Schimmelpenninck Van Der Oye, placed Duivenvoorde into a foundation. The castle has been open to the public since 1963. Entire rooms remain intact and there are many personal belongings with historical value, making a visit to the castle feel like a journey through time.

HOL MER.”. “MO.NO.ARG.REG.BELGII.” is the Latin abbreviation for “Moneta Nova Argenta Regni Belgii”: New Silver coin of the Kingdom of the Netherlands. “HOL MER.” stands for the province of Zuid-Holland.

On the reverse of the Silver Ducat, the National coat of arms of the Netherlands with the Royal Crown between the numbers of the year can be found.
