1 Gold Ecu - Henry of Brederode

Vianen was a tiny lordship wedged between Utrecht and Holland, and its mint operated largely because Reinoud III van Brederode — Henry's father — had fought hard to maintain minting rights against persistent pressure from the Habsburgs. Henry inherited both the title and the legal battle. The lords of Vianen exploited every ambiguity in Imperial minting law to keep striking gold, often producing ecus that closely tracked French and Burgundian weight standards to ensure merchant acceptance far beyond their borders.

Delmonte lists this type as genuinely scarce. The Brederode line died out in the male line with Henry himself in 1568.
