Obole - Guy de Prangins

Guy de Prangins served as Bishop of Lausanne from 1375 to 1394, a period when the bishopric was caught between competing pressures from the Duchy of Savoy and the Swiss Confederation. His episcopal coinage rights were a practical assertion of jurisdictional independence at a moment when both neighbors were systematically absorbing smaller sovereign authorities in the region. Billon issues of this weight from Lausanne circulated primarily in local markets around the Léman basin, where Savoyard deniers and Bernese pfennigs competed directly for everyday transactions.
