Frequently Asked Questions

What is the difference between fineness and karat?

Both measure purity. Fineness uses parts per thousand, such as .999; karats use parts per 24, so 24-karat gold is pure gold.

Is a troy ounce the same as a regular ounce?

No. A troy ounce is 31.1035 grams, about 10% heavier than the avoirdupois ounce used for everyday goods.

What is the difference between a coin and a round?

A coin is issued by a government mint and has a face value; a round is privately made and is not legal tender.

Where can I learn about a specific company's terms?

Read the company's own written terms. For one example, our Goldco review explains how that precious metals company works.
