A gold carat is 1/24 section, or 4.1667%, of the entire, and the immaculateness of a gold compound is communicated as the quantity of these pieces of gold it contains. In this way, an article that contains 16 sections of a gold purity chart and 8 sections of alloying metal are 16-carat gold, and unadulterated gold is 24-carat gold.

The virtue of the coin was then communicated by the extent of its carat weight that was contributed by gold.
