The Double Gold Ducat is minted in proof quality and is offered on a reservation only basis until the end of May. Sales will then close and the mintage will be restricted to the number of orders received. In 2017 only 836 Double Ducats were issued. It is expected that the remaining coins on the aftermarket will be only a small amount.
The coin is made of the long-time Dutch ducat standard of .983 fine gold. It weighs 6.988 grams and is 26 mm in diameter.
