I ran across it when @glenalbrethsen were discussing becoming millionaires by stacking pennies over on my stacking copper post...
- According to that pdf...
- For 10 million pennies you would only need 6' x 6' x 6' to store them,
but they would weigh 31.3 tons. - If you stacked them it would only be a 9.88 mile high stack.
- So having a few might be OK,
but you could never move if you stacked millionaire proportions... haha

That is a LOT of pennies. Still, If I had a million dollars in pennies I am sure I could find the space for them :)
