Note 17 — Valentine Visconti.
Reading edition
The florin, the Venetian ducat, and the French franc were interchangeable coins worth about nine-and-eightpence of our money. They are the equivalent of our half-sovereign, the French crown that of our half-guinea; the Burgundian noble being, I think, the only coin that reached the value of the modern guinea. See the tables for 1384-1394 in De Wailly.
