Rijksdaalder

17th century rijksdaalder was set to be equal to from 48 to 50 stuivers (the Dutch equivalent of shillings) and circulated along with silver florins (28 stuivers), daalders (30 stuivers), leeuwendaalders (36 to 42 stuivers; 27.68 g, 0.743 fine), silver ducats (48 stuivers; 28.06 g, 0.868 fine), and ducatons (60 stuivers; 32.46 g, 0.938 fine) silver ducats and rijksdaalders were almost of the same size and quality. With the disappearance of the original armored half bust rijksdaalder design, silver ducats and later 2+1⁄2 guilders started to be called rijksdaalders.
