One million pennies have a face value of $10,000. According to a USA Today article, the total weight of a million pennies is approximately 3.6 tons.
If packaged into rolls for easy handling, the million pennies equal 20,000 50-coin rolls in total. According to the Consumerist website, the cost incurred by the U.S. Mint of minting each of those pennies in 2013 was 1.8 cents, making the actual cost of one million pennies an expensive $18,000. The high cost of creating a penny is due primarily to the raw cost of the zinc and copper used to form the coin.
