The term “gold/silver ratio” refers to the amount of silver it would take to purchase one (1) Troy ounce of gold. If you want to figure out the gold/silver ratio for yourself, simply take the spot price of gold and divide it by the spot price of silver.
Historically, the gold/silver ratio has fluctuated. In Ancient Rome it was set at 12-to-1. In 1792, the United States set it at 15-to-1. Recent years have seen the gold/silver ratio fluctuate much higher.
