Fine and rough weight

from Wikipedia, the free encyclopedia

As a fine weight (also net weight or grain ) is defined as the mass of a alloy containing the precious metal , especially for coins or jewelry . It is given in a customary measure of mass, for example grams .

The total mass including the non-precious metal parts (often copper ) is called rough weight (older spelling rough weight , also gross weight or shot ).

The ratio of fine to rough weight is called fineness .

In the past, the fine weight of the silver or gold used was the only decisive factor in determining the value of coins . Fine and rough weight were determined by the coin rate.
