Ducaton 'Silver Rider' Amsterdam, piedfort of double weight

1672 was the Rampjaar — the Disaster Year — when French forces under Louis XIV overran five of the seven Dutch provinces within weeks, leaving Holland and Zeeland isolated behind flooded polders. Amsterdam's mint continued striking through the crisis, and piedfort issues like this double-weight example almost certainly served as presentation or test pieces rather than entering circulation, produced to demonstrate striking quality to mint officials or municipal authorities at a moment when institutional confidence needed visible reinforcement.

The standard Ducaton 'Silver Rider' was the workhorse of Dutch trade coinage; a piedfort at 65g is a deliberate departure from that function entirely.
