Older pennies weigh more because they were made using a higher percentage of copper in their composition, whereas newer pennies have a lower percentage of copper and are mostly made of zinc. The difference in composition accounts for the difference in weight between old and new pennies.

How much does a roll of US pennies weigh?

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.

How many pennies weigh 34 lbs?

This is a trick question - it depends on the pennies' dates, so there's no simple answer. Pennies made in 1981 and earlier weigh 3.11 gm each. 1983 and later weigh 2.5 gm each. And to get even more confusing, some 1982 cents weigh 3.11 gm and some weigh 2.5 gm!! If you assume the coins are all relatively new you can use the 2.5 gm figure. A pound is 453.6 gm, so grab your calculator and go from there.
