Question: how much is 30 lbs of pennies worth?
Answer: Zinc is denser than copper so post-1982 cents weigh 3.11 grams or about 146 to a pound. So how much is 30 lbs in pennies? Depends on the proportion of new and old cents. But somewhere between $43.80 (if they're all post-'82) and $54.30 (if they're all pre-'82.)
