Should one invest $1000 in - Copper Silver Gold (Platinum/Palladium) Investing in the right metal is the difference of making some money over very little money...assuming that Congress ever elects to let folks melt down copper cents to begin with. Sorting/hoarding copper cents never made much sense to me, but to each their own. I'd rather buy silver and gold.
At the end of the day it will never be profitable to melt pennies if copper doesnt go over 6 bucks a pound even then no reasonable scrap yard will pay you 6 bucks a pound for a lump of not pure copper because of the 5% zinc and tin. Even if you get it out more time and money its just not worth the hassel
The problem with the google result you found is that 2.4 cent figure is the THEORETICAL price you would get if they valued the copper in the cent at the spot market price for pure copper. In the REAL world since the copper is alloyed with zinc you would not get the spot price as it would have to be melted refined and purified which all cost money. In the real world you would get about 25% of the spot copper price. Which is why copper would have to go over $6.00 a pound just to break even. Any less than that and they are worth more as spendable coins than as metal.
