Ducaton
The ducaton, ducatone or ducatoon was a crown-sized silver coin of the 16th-18th centuries.
The first ducaton-type coin was the scudo known as the 'ducatone da soldi cento' (of 100 soldi), issued by Charles V, Holy Roman Emperor, in Milan in 1551. Ducatones were produced in greater numbers in numerous Italian states through the 17th century, spreading to other parts of the Spanish Empire, including Burgundy and the Netherlands - in 1618 the ducaton was produced in Brabant and Tournai comprising 32.48 grams of 0.944 silver depicting Albert and Isabella.
