Thomas Platter's Annual Income from the Basel Printing House c.1540s
Thomas Platter, a former rope-maker and autodidact who rose to become a master printer in Basel, reported in his autobiography that the printing side of his partnership — which produced landmark humanist and Reformation texts including editions associated with Erasmus and Calvin's Institutes — yielded him approximately 200 Rhenish florins annually after expenses. Platter and his partners had purchased Andreas Cratander's press for 800 florins, and the shop competed in the Frankfurt book fair circuit alongside Basel's other great printing houses: Froben, Amerbach, and Oporinus, with whom Platter had briefly been in partnership. The Rhenish gulden of this period had a gold content of approximately 2.5g fine gold under the post-1559 Reichsmünzordnung standard; applied retroactively to the 1540s figure it yields an approximate gold equivalent, and the self-reported nature of the income figure warrants treating the conversion as estimated.

Jean-Marc Vacheron's Apprenticeship Premium for Watchmaking Training 1755
In 1755, master watchmaker Jean-Marc Vacheron — founder of what would become the world's oldest continuously operating watch manufacturer — received 1,000 Geneva florins as an apprenticeship premium from the family of Esaïe Jean François Hetier in exchange for five years of personal instruction in the watchmaker's craft. This fee structure was regulated by the Maîtrise des Horlogers de Genève, the world's first dedicated watchmakers' guild, established in 1601 when Calvin's sumptuary laws suppressing jewellery and goldwork had pushed the city's goldsmiths into clockmaking a generation earlier. The Geneva florin was a silver-based account currency; the gold equivalent is estimated from its silver content of approximately 2.09g fine silver per florin at the prevailing 1:14.5 silver-to-gold exchange ratio.
