English Coin Scale
Pic  DC 7

John Greaves & Son

Sovereign scale with equal arms and pressed platters at both ends of the beam. It was pre-loaded to weigh the half-sovereign, and a disc-shaped weight was added to the weight platter to weigh a sovereign. This weight could also be used to test the accuracy of the scale by placing it in the coin platter, as the weight was almost the same diameter as a half-sovereign. The slide on this design was unusual in having vernier graduations for fractions of a penny - a more accurate method of reading than simple division. The balance was contained in a slender maroon covered leather case.
