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.
