US Pennies were made of 95% copper (with the exception of the 1943 steel cent) from 1864-1982. Midway through 1982, the cent switched to copper plated zinc. So any penny dated 1983-present is just copper plated zinc. However a coin dated 1982 could either be 95% copper or copper plated zinc. A copper coin should weigh about 3.11 grams while the zinc pennies are lighter at about 2.5 grams.

How much is 130lbs pennys us weight in dollars?
It depends on the year. Before 1982, pennies contained 95% copper and 5% zinc. Those minted after 1982 are 97.5% zinc and 2.5% copper. Today's pennies weigh less. So if the majority of the pennies are after 1982, you would most likely have about 23,586 pennies, which is equal to $235.86 USD. If the majority of the pennies are before 1982, you would most likely have 18,960 pennies, which is equal to $189.60 USD. But then again you can smelt the pennies and sell the copper. I hope this helped you. :)

Why do pennies from the 1970's have a greater mass than pennies from the 1990's?
Because Lincoln cents until 1982 (Some 1982 cents are copper, others are zinc) were struck in 95% copper, starting in 1982 they are made of mostly zinc with a small plating of copper. Since copper has a greater mass than zinc they weigh more. Copper pennies are also worth more than zinc pennies, if it was legal to melt them down, you could get about 2 cents for every copper penny but only about half a cent in scrap for zinc pennies. However, at the time being it is illegal to melt down US pennies in the US or export them to be melted down.
