Gold Guyennois - Edward of Woodstock

Edward of Woodstock — the Black Prince — received Aquitaine as a principality from his father Edward III in 1362, a transfer that prompted a fresh coinage program appropriate to a sovereign prince rather than a mere duke. The guyennois was part of that assertion of independent authority over the territory. Edward's Aquitanian administration collapsed under the financial strain of the Castilian campaign and the ruinous chevauchées; he returned to England sick in 1371 and surrendered the principality the following year, making the 1362–1372 window the entirety of this type's production lifetime.
