Modern zinc (1982-present) pennies weigh 2.5 grams each, and copper pennies (pre-1982) weigh 3.11 grams each. 50 new ones weigh 125 grams and 50 old ones weigh 155.5 grams. A mix of the two weighs somewhere in the middle.
50 US pennies would weigh about .338 pounds.

A $50 bag of pennies weights 34.2 lbs. I worked in a coin vault at a Federal Reserve Bank.

What else can I help you with?
