Ducat coin scale Nuremberg
Pic CS 9
This ducat scale was made by Paulus Deinert, Nuremberg, Germany between 1758 and 1783, when he died. It is a fascinating combination of equal-arm two-pan balance and pendulum or inclination balance. the left pan is heavier than the right pan by an amount equal to the weight of a gold ducat, so NO weights are needed. If the coin is underweight, the beam comes to rest in a inclined position, and the amount underweight is indicated on the quadrant fixed between the pointer and the beam.

Paulus Deinert´s maker sign was an ostrich below his initials from 1747 until 1758, then he adopted the cupping-glass sign previously used by his brother-in-law, Johann Loss. The cupping-glass can be seen at the top of the paper label.

The paper label say: " Ein Wäglein ohne Gewicht einen Ducaten zu wiegen auf den Bogen für die Eße abgeteilet a 1 bis 6 "
