It would take 20 million nickels to make $1 million. A United States nickel is worth five cents, so $1 is the equivalent of 20 nickels.
Multiplying 20 nickels per dollar by $1 million yields a total of 20 million nickels. It would also take 100 million pennies, 10 million dimes, four million quarters or two million half-dollars to equal $1 million. To make $1,000, it would take 20,000 nickels, 100,000 pennies, 10,000 dimes, 4,000 quarters or 2,000 half-dollars. Because one nickel has a thickness of approximately 0.077 inches, $1 million worth of nickels would stack slightly more than 24 miles.
