Watch List notes:

COMMEMORATIVE MEDALS, WORLD MEDALS, Netherlands, The Successful Outcome of the Attempted Attack on Amsterdam by William II and the Imprisonment of the Regents in Loevestein, Cast Silver Medal with reverse in imitation of engraving, unsigned (Pieter van Abeele), c.1650, cityscape of Amsterdam with spires and windmills, the harbour to the fore with several city barges, hand of God in clouds above and legend on scroll, rev two coaches leave a gateway above which hangs a smoking cage, troops march alongside, the castle of Loevenstein beyond, 64.5mm (vL II, 345, 1; Fred 1b, 26). Very fine and very rare.
William II, unhappy with the Treaty of Münster and the State of Holland's wish to reduce troop levels, attempted a surprise attack on Amsterdam. This failed and the medal's reverse compares the imprisonment of the Regents with the attempt by Herman de Ruyter to capture Loevenstein.

Estimate: £3000-3500
