The value of a gold bar depends primarily on its weight and the current market price of gold per ounce. As of mid-September 2025, the price of gold is approximately $3,663 to $3,687 per troy ounce. The most common gold bar size, the 1-kilogram bar (about 32.15 troy ounces), is worth roughly $113,618 based on recent prices around $3,534 per ounce in early September, and would be slightly higher with the more current prices around $3,663 to $3,687 per ounce. Smaller bars, such as a 1-ounce bar, would be worth close to the price per ounce of gold, about $3,663 to $3,687. Larger bars like the standard 400-troy ounce bar, often held by central banks, can be worth over $1.1 million. In summary:
