melting down pennies

melting down pennies
Ok, so I had a thought. Maybe if I share it, you guys can help me work through the problem.
(I'll mention, its not something I'm considering doing myself.)
Copper is a precious metal and is getting pretty expensive these days. That is why people are raiding old houses and telephone poles for it.
"Copper has always been an enticing metal for people to steal because it's 100 percent recyclable. It's easily recycled, and it's relatively plentiful and accessible," said Ken Geremia, manager of communications for the Copper Development Association, an arm of the U.S. copper, brass and bronze industry."

There is also a myth I have heard that the value of a penny is worth more than 1 cent merely because of the price of copper. I'm not sure if this is true or not.
Now, copper melts at about 1000 degrees celsius (according to Wikipedia).
So, what if you could exchange your money in at the bank for pennies, then manage to smelt all those pennies down (because I don't think you can sell pennies for scrap). Would that work?
I've also considered that the process of smelting could get quite expensive, but a furnace that heats to 1000 degrees, is that likely? Could a campfire get that hot?
(I spent a bit of time trying to google "melting pennies down fo scrap" but haven't found anything too conclusive. If sure if I spent long enough on the problem I could figure it out...but I thought I'd post the problem up here.)

I know an electrician who collected scrap pieces of copper wire on construction sites for 3 or 4 years
he would strip them all and sell them to scrap yards or whatever places buy metals. he eventually had enough money for a down payment on a new car.

not sure about the Canadian mint but here is what the US mint says:
http://www.usmint.gov/about_the_mint...ion=fun_facts2
The alloy remained 95 percent copper and 5 percent zinc until 1982, when the composition was changed to 97.5 percent zinc and 2.5 percent copper (copper-plated zinc). Cents of both compositions appeared in that year.
damn!
...but maybe if you got some old pennies....
is zinc worth anything?

might help a bit..
i didn't read it.. just found it

actually the price of number one copper isn't that great right now, it has gone down a lot since the summer when it was getting close to 4 dollars a pound.
and if you did melt them down it would be considered number two copper as far as I know

my neighbour does that and i think he's an electrician!!! he's always outside stipping down wire and selling em to scrap yards....**** it...im gonna take some wire from him!

all the left over copper from A/C lines adds up pretty quick
#13
we pulled a 'caper' and scored $440 from the scrap yard for 3 hours work (two guys).. just cutting and pulling cat5e cabling out of a building (with permission from the owner)
the penny will be around as long as it's worth it for the government (worth less than $0.01), when metal is worth more than the canadian cent, you'll see it disappear.

yeah like everyone said the penny isn't pure copper so it isn't worth it to melt down.
Now for the furnace, it is possible to make a small furnace that can melt down most things. Using charcoal briquettes and compressed air, it is possible to produce an immense amount of heat.

i'm not going to read all that
wish i had time for that kind of hobby

math maybe (pennies = pre 1982= 3.1 g, post 1982 = 2.5 g) , so 1 lb = 453.59237 g
454 g = 3.60$
pre 1982 = 454/3.1 = 146 pennies so it'll take $1.46 to make $3.60
post 1982 = 454/2.5 = 181 pennies so it'll take $1.81 to make $3.60
454 g = 3.60$
pre 1982 = 454/3.1 = 146 pennies so it'll take $1.46 to make $3.60
