Douzain - Francis I 1st type

The douzain — worth twelve deniers — was the backbone of everyday French commerce throughout the sixteenth century, and Francis I's first type dates to the closing years of a reign defined by near-constant war expenditure against Charles V. Repeated campaigns in Italy and along the northern frontiers demanded enormous fiscal output, and the billon coinage bore much of that pressure through successive debasements. By the 1540s, the silver content of circulating billon had been reduced to the point where the douzain's intrinsic value was a fraction of its face.

The absence of a Ciani reference is notable — copies of that catalogue frequently omit transitional billon types that fall between major reform coinage.
