A US Federal Reserve Note weighs exactly 1 gram, regardless of denomination. One kilogram of Federal Reserve Notes could be as little as $1000, or as much as $100,000, depending on the denomination of all the bills.
500 kilograms of Federal Reserve Notes, therefore, could be worth as little as $500,000, or as much as $55 million.
The current average price of gold per kilogram as of 6/27/2026 is $131,000 to $131,500. Assuming the price of gold per kilogram is $131,000, 500 kilograms of gold would be worth $65.5 million.
