Neither is. Density only depends on the substance, not on how much of it there is.
10,000 i guess
One mile is 1609344 mm. A US nickel is 1.95 mm thick, so a mile-high stack would contain 1609344 / 1.95 = 825,305 coins, rounded to the next-highest whole number. Each nickel is worth 5 cents so the stack's value would be 825305 * 5 = 4126525 cents, or $41,265.25
A penny weighs approximately 2.5 grams. There are 5,280 feet in a mile, so there are 5,280 * 12 = 63,360 inches in a mile. Since pennies are 0.75 inches in diameter, you would need (63,360 / 0.75) = 84,480 pennies to make a mile. Therefore, a mile of pennies would weigh approximately 211,200 grams or 466 pounds.
4000000 pennies is exactly 4000000 pennies.

A penny is 0.065 of an inch. So there is about 974,770 pennies in a mile. A light year is about 5.87849981 × 10^12 miles So there would be 5.7301852597937 x 10^18 pennies in a light year Or better still £5.7 quintillion

"Stack those boxes over here", said the receiving clerk. I could eat a mile high stack of flapjacks! When an airport has a traffic jam in the sky, the controllers stack the incoming arrivals according to how much fuel each airplane has left.

$1,389,473,684.20 Assuming that a single bill is 0.0043 inches thick. You would have to have a stack of 100's 10,795.45 miles high to equal the United States national debt of 15 trillion dollars.

1 dollar bill is .00011m thick or .011cm 1 mile = 5280ft (x12 in/ft) = 63360in (x2.54cm/in) = 160934.4cm 160943.4cm / .011cm = 14630400 $14,630,400
100 dollar bills would stack 44 inch high
Approximately $22,900
