All pennies minted after 1982 weigh 2.5 grams each. (Older pennies weigh 3.11 grams) Newer cents are made of zinc because the price of copper increased so much that a copper penny was worth more than one cent.

So a roll (50 pennies) would weigh (2.5g times 50 = 125 grams) (125g divided by 28.35 ounces = 4.41oz) (4.41oz divided by 16oz =.28lb) Summary. 50 pennies (1 roll, not counting paper in the roll) (add about 1.5g for the paper) = 125 grams or = 4.41 Ounces or = .28 Pounds or = Probably almost 1/3 of a pound counting the paper.
