Between changing the composition of the US one-cent coin (often referred to as a "penny," even though the word has never appeared on the US coin) and experimenting with the size of the date, there are 7 different types of 1982 pennies: * 1982 copper, small date * 1982-D copper, small date * 1982 copper, large date * 1982-D copper, large date * 1982 copper-plated zinc * 1982-D copper-plated zinc * 1982-S copper proof It's easy to tell between the different mint marks; just look below the date. The plated zinc cents are slightly lighter, and don't give the distinctive "ring" of a copper (actually a copper-zinc alloy) cent. The only way to tell between the date sizes is to study pictures of the two, and notice the distinctions in how they look. Note that there was only one proof type, minted only in San Francisco.
The weights are different. Pre-1982 pennies are 95% copper and weigh 3.11 grams. Newer ones are mostly zinc and weigh 2.5 grams.
Presuming that you are asking about US Lincoln pennies, the answer is that it depends. If the pennies are pre-1982, they are 95% copper and 5% zinc and weigh 147 to the pound. If the pennies are post-1982, they are 2.5% copper and 97.5% zinc and weigh 181 to the pound. In 1982, both types were made. In 1943, pennies were made from steel coated with zinc (so-called "silver pennies" or "steel pennies") and in 1944 (and I think 1945 as well) from old brass shell casings, so their counts would be a bit different.
US pennies switched from copper to zinc due to the rising price of copper. Zinc is much less expensive.
Pre 1983 pennies at 153.5 pennies per pound. = 26.058 pounds and at today’s
There are a lot of different pennies in the world, but 11.34 US pennies minted since 1982 will weigh one ounce. It would only take 9.145 older pennies.
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.
If the pennies were pre-1982 then 9 US pennies are very close to 1 ounce (9.145 pennies = 1 ounce). If the pennies are after 1982 then 11 US pennies are very close to one ounce (11.34 pennies = 1 ounce).
The pre-1982 pennies are 95% copper and 5% zinc. Post-1982 cents are 97.5% zinc and 2.5% copper.
Up into 1982, US pennies were 95% copper, but that year the composition was changed and now they're 97.5% zinc.
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. :)
The copper in a US cent made before 1982 is worth almost 2 cents. Those made after 1982 are worth much less than 1 cent (but the cost of producing them is about 1.5 cents). Both types were made in 1982. But before you start sorting your pre- and post 1982 pennies, you should know that there is an administrative order prohibiting the "melting or exporting of large numbers of one and 5 cent coins" which could result in a fairly large fine.
100 pennies = 1 pound.
Pennies from 1982 and before were all copper
Considering all the pennies are Mid 1982 or newer, 220.46226 lbs A lb = 453.6 grams Pennies Mid 1982 weigh 2.5 grams and 3.11 grams prior to mid 1982. -G-Saint..
if they are all made after 1982 100 lb's of pennies is $181.44
No, pre-1982 pennies are 95% copper and post-1982 pennies are made out of mostly zinc with a thing copper coating
Of 1131 pennies, x weigh 3.09 g and y weigh 2.51 g. In total, the 1131 pennies weigh 3001.8 g. 3.09x + 2.51y 1131 = 3001.8 I have no idea what to do after that, or if it's even right. I was thinking maybe dividing, but the number was so small it had to be wrong. Tell me, what grade is this for?
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)
Food was definitely less expensive in the UK in 1982 than it is in 2014. A loaf of bread was about 32 pennies while a pint of beer was about 73 pennies. A pint of milk was about 20 pennies at this time.
Before 1982, there were 145 pennies in a pound. After 1982, there are 181 pennies per pound. So, doing the math 37 x 145 = 5365 or $53.65 37 x 181 = 6697 or $66.97
Pennies produced in 2004 were made from copper-plated zinc. Pennies with 95% copper metal have not been produced since 1982.
The value of this coin will vary depending on the year it was minted. Pennies minted before 1982 are valued at $5. Pennies minted after 1982 are valued at $2.
Pre-1982 pennies are made of bronze, which is 95% copper plus 5% tin and/or zinc. Post-1982 pennies are zinc with a thin coating of copper.
