Gold ingots are bars of pure gold that were cast in a mold, unlike gold coins which are stamped under a press. They have this rectangular shape simply for convenience of transport.
The weight of gold ingots varies from a mere gram to several kilograms; the "London Good Delivery Bar" weights in at 400 ounces, or 12.5 kilos. At today's price, each bar is worth nearly 400,000ドル!
