Depending on which penny, there is a range of weights.

It depends very much on which country issued the coin and its date. Some of the most common coins are:

British pennies:

1707-1796: 0.5 gm

1797: 28.3 gm

1798-1859: 18.8 gm

1860-1970: 9.4 gm

1971-present: 3.56 gm

US cents (universally called "pennies"):

1793-1796: 13.48 gm

1796-1857: 10.89 gm

1856-1864: 4.67 gm

1864-1942: 3.11 gm

1943 2.67: gm

1944-1981: 3.11 gm

1982: 3.11 gm or 2.5 gm depending on composition

1982-present: 2.5 gm
Assuming you are referring to United States Lincoln cents: 1909-1981 (except 1943) (95% Copper and 5% Zinc) - 3.089 grams (147 to the pound) 1943 pennies are steel with a zinc coating and weigh about 2.7 grams (about 168 to the pound). 1983- to date (2.5% Copper and 97.5% Zinc) - 2.500 grams (181 to the pound) In 1982, both the 95% copper and 97.5% zinc varieties were made - there is no easy way (other than by weighing them) to differentiate between them.
