How the gold price in Chicago is calculated
We take the live spot price of 4,127.80 USD per troy ounce, divide it by 31.1035 to get 132.71 USD per gram of pure gold, and multiply by today’s exchange rate of 1.0000 USD per dollar. That gives 132.71 USD per gram for 24K. Lower karats are priced by their gold content.
In the US, gold is quoted in dollars per troy ounce. Jewelry is mostly 14K and 10K, while bullion coins such as the American Gold Eagle (22K) and Buffalo (24K) sell at a premium over spot. Sales tax on bullion depends on the state.
Gold in Chicago is priced in the same currency as the rest of United States; differences between shops come from margins and making charges, not from the metal price.
Before you sell, weigh your pieces on a jeweler’s scale, check the hallmark and compare at least two quotes. Read our guide to selling gold.
