2 million pennies are equal to $20,000. 1 million pennies are equal to $10,000.
There are 100 pennies in 1 dollar, so to figure out how many dollars are in any amount of pennies, you just divide the number of pennies by 100. To find out how many pennies are in any amount of dollars, you just multiply the dollar amount by 100.
It would be extremely difficult to carry 2 million pennies around with you, because altogether they weigh 7.6 tons. That's about the same weight as a large elephant.
In 2004, a man tried to cash in $10,000 worth of pennies (1 million pennies), but was unable to do it without going to a bank and cashing in $100 per week for about 2 years. Banks have limits on how many pennies they can exchange for bills.
