About 181 pennies per pound.
It depends how many pennies is in a pound of pennies.1.482 dollarsCorrection and ExplanationAssuming you have US cents minted after 1982, they weigh 2.5 grams each. There are 453.6 grams in a standard pound, so that means a pound of pennies consists of 453.6/2.5 = 181.44 coins, or a bit more than $1.81If the coins are dated before 1982 they weigh 3.11 grams each so a pound would be 453.6/3.11 = 145.8 cents, or about $1.46
Cents weigh different amounts depending on their dates. Before 1982, cents weighed 3.11 grams. Cents issued after 1982 weigh 2.5 grams. Cents issued DURING 1982 could weigh either amount (is this getting complicated enough?) A pound is equivalent to 453.6 gm, So with pennies made before 1982 it would take 146 pennies to get 454.6 grams... With pennies made after 1982 it would take 182 pennies.
There are 100 pennies in a pound. Therefore, 1000000 pennies is equal to 1000000/100 = 10000 pounds.
240 copper pennies equal a pound.
if they are all made after 1982 100 lb's of pennies is $181.44
Now it is 100 pence to the pound. Pre decimal currency, there were 240 pennies in a pound.
145 pennies (pre 1982) 181 (1982 and beyond). 1982 and newer pennies contain mostly zinc and pre 1982 pennies are 95% copper. Some 1982 pennies are 95% copper but not all so if you're buying for copper content stick with pre 1982 to be on the safe side. The above mentioned is pennies in a pound. to figure out pennies "in a pound of copper you must multiply "for pre 1982" 145 X 95% "copper content. Since your 5% short of copper per penny you multiply 145 X 5% to get 7.25. Add 145 to 7.25 to get 152.25 pre 1982 pennies in a pound of copper.If you mean how many pennies can you make from one pound of copper the answer is:There is 2,5% copper in the penny (the rest is mostly zinc)so you need 40 pounds of pennies to have one pound of copper.Each penny weighs 0,080 troy ounces40 pounds is 583,33 troy ounces (see why I like the metric system?)583,3 / 0,8 = 7291.66...About 7293 pennies (almost seventy three dollars in pennies)(some will be used and have corroded if that makes a difference... I do not know)
