If the pennies are post-1982, they are 2.5% copper and 97.5% zinc and weigh 181 to the pound. In 1982, both types were made. In 1943, pennies were made from steel coated with zinc (so-called "silver pennies" or "steel pennies") and in 1944 (and I think 1945 as well) from old brass shell casings, so their counts would be a bit different.
