There are many countries that have pennies as their minor currency unit and they have different masses. Since you have chosen not to state which country's currency the question is about, it is not possible to provide a more useful answer.
500 to 600 pennies
There are 100 pennies in a pound, so 100 pounds of pennies would equal 10,000 pennies. Since there are 100 pennies in a dollar, this would be equivalent to $100.
A thousand pennies, which equates to $10, would weigh about 2.5 pounds since each penny weighs approximately 2.5 grams.
if they are pre-1982 US 95% pure copper pennies figure 95% of price of copper per lb X 100. if copper is $4 lb, then approx $390 for 100 lbs.
10 pennies...
100 pennies = 100 [pennies].
50 pennies of course.
Both a pound of pennies and a pound of dimes would weigh the same, as they both weigh a pound. The difference lies in the quantity of coins; a pound of dimes would have fewer coins because dimes are heavier than pennies.
A penny weighs approximately 0.088 ounces, so a 30 lb bag of pennies would contain approximately 6,840 pennies (30 lbs x 16 oz/lb / 0.088 oz/penny). Therefore, a 30 lb bag of pennies would be worth $68.40 (6,840 pennies x $0.01/penny).
125 pennies
There are 307,087.5 pennies in one ton of pennies
It would depend on how many pennies they had!
