Does an old pennie have the same density of a new pennie?
No because they are of the same volume but different mass. Pre 1982 pennies were I think 95% copper and 5% zinc. Now they are something like 2% copper and the rest zinc. The density of zinc is 7.13g/cc and copper is 8.92g/cc. They should be less dense no than they were.

That will depend upon the pennies being weighed. Uncirculated copper pennies minted 1909 to 1982 (not including zinc 1943) are heavier than the new zinc pennies that started in 1983. Fifty pounds of the old copper pennies would be about $72.50. Fifty pounds of the new zinc pennies would be about $90.00.
