Coin Scale
Pic Coin  DC 3

Hydrostatical money scale. The coin is placed in the clip hanging below the small pan and is weighed in the normal way. It is then re-weighed with the coin immersed in water, and with a special water-weight the pan above the clip. Coins of true weight, made of proper coin gold, will be in equilibrium in both air and water. The beam and pillar are stored in the box
