Netherlands
The Dutch Golden Age was also a golden age for gold-denominated record-keeping — the Amsterdam Exchange Bank, founded in 1609, brought a new precision to commercial accounting that extended into the art market, guild registers, and probate inventories that make seventeenth-century Holland one of the most researchable creative economies in history. The Dutch guilder’s relatively stable silver content across this period provides a consistent conversion framework, and the sheer volume of surviving records — notarial acts, auction catalogues, estate inventories — means the Netherlands can eventually support more database entries per capita than almost any other territory. The same merchant culture that produced Rembrandt also produced the paperwork to prove what they paid him.
