That would depend on what pennies you are talking about (i.e., from what country). Look up the weight of the penny for your particular country, then multiply it by a million. Here is a list of pennies:

For example, the U.S. penny has a mass of 2.5 gram; multiplied by a million gives you 2500 kg. or 2.5 tonnes.
How much would US$1000000 in $100 bills weigh
US cents ("pennies") minted since mid-1982 weigh 2.5 gm each. There are 100 cents in a dollar so a million dollars' worth would be 100 million pennies. At 2.5 gm each their total weight would be 250 million grams. Converting to more-manageable units, there are 1000 grams in a kilo and 1000 kilos in a tonne, so there are a million grams in one tonne. Therefore 250 million grams is 250 tonnes. A large car weighs around 2 tonnes so figure the pennies would weigh about as much as a 125 cars.
A million times as much as in one dime. * * * * * I would have said that, since 10 pennies = 1 dime, it would be 10 million pennies.
1,000,000 British pennies would be 66666.6666666032 feet, 1,000,000 American pennies would be 62499.9999999405 feet, 1,000,000 Australian pennies would be 101049.868766308 feet, and 1,000,000 Canadian pennies would be 62499.9999999405 feet (the same as the American 'penny').
A typical cow may weigh around 1000 pounds, so that is 1000000/1000 = 1000 cows

One penny weighs 2.5 grams, so 3,500 pennies weigh 8,750 grams.

A US penny weighs approximately 2.5 grams. So, 1 million dollars in pennies would weigh around 22,680 kilograms, or 50,000 pounds.
1,000,000 British pennies would be 66666.6666666032 feet, 1,000,000 American pennies would be 62499.9999999405 feet, 1,000,000 Australian pennies would be 101049.868766308 feet, and 1,000,000 Canadian pennies would be 62499.9999999405 feet (the same as the American 'penny').
One billion pennies would weigh 10,000,000 pounds, which is equivalent to 5,000 tons.
38000 copper pennies would weigh approximately 94.7 kilograms or 209 pounds.
A single penny (after 1982) weighs 2.5 grams, so 10,000,000 pennies would weigh 25,000,000 grams, 55,115.5655 pounds, or 27.5577827 short tons.
Pennies weigh about 2.5 grams each. There are roughly 181 pennies in a pound and 2,381 pennies in a gallon. So, a 1 gallon water jug filled with pennies would weigh approximately 9.5 pounds.
A typical cow may weigh around 1000 pounds, so that is 1000000/1000 = 1000 cows
1 billion pennies would weigh 5,511,556.55 pounds. The weight of a penny is 2.5 grams
