Ducaton `Zilveren Rijder` piedfort at double weight

Piedforts of the Zilveren Rijder were never intended for circulation — produced at double the standard flan weight, they served as presentation pieces and official record strikes, distributed to magistrates, mint officials, and occasionally foreign dignitaries as proof of die authenticity and minting rights. Gelderland maintained its own mint at Harderwijk with considerable jealousy, frequently clashing with the States-General over the right to strike rijders independently of Holland's preferred uniformity agreements.

The twenty-year span of this type reflects ongoing die use rather than continuous production. Individual piedfort strikes were likely made in very small numbers at irregular intervals, which explains the bibliographic chaos — Voogt, Delmonte, and KM do not fully agree on die marriage attributions within the series.
