The first documented use of gold by humans was found in the jewelery recovered from the Varna Necropolis in Bulgaria and dated to about 6,500 years ago. Since then, enough gold has been mined from Earth's crust to form a cube 60 feet on a side.
Gold is one of the 100-odd basic elements in the universe. Number 79 in the element list, a cubic meter of it weighs 19 metric tons. Your 'weight in gold' would be worth over $2 million!
