Medieval copper alloy French jetton dating to the period c. AD 1418 - 1437. Crown type. Probably struck at Paris. See: Mitchener, M, 1988, p. 194, no. 535.
The unusual weight and thickness of this example suggests it may be piedfort.
Introduction of thicker and heavier piedfort jettons during the 15th century appears to have resulted from the popularisation of a new method of performing calculations in manual accountancy. A collection of stationary jettons which were heavier and thicker were issued as reference points for the lighter mobile jettons in order to make these calculations.
