The gold-silver ratio, also known as the mint ratio, refers to the relative value of an ounce of silver to an equal weight of gold. Put simply, it is the quantity of silver in ounces needed to buy a single ounce of gold. Traders can use it to diversify the amount of precious metal they hold in their portfolio.
