100 Francs Rene Descartes

Issued as part of France's long-running commemorative program, this piece marks the 395th anniversary of Descartes' birth — an oddly non-round milestone that reflected a scheduling decision tied to broader ministerial planning rather than any numerological significance. The French Treasury had by this point turned the 100 Francs silver commemorative format into a near-annual vehicle for cultural figures, with output quality varying considerably across the series.

Descartes died in Stockholm in 1650, likely of pneumonia, having been summoned by Queen Christina to tutor her at five in the morning — a schedule his famously delicate constitution could not survive.
