In theory, a coin should contain metal equal in value to the face value of the coin. (Otherwise, you could make a nice profit buying coins, melting them down, and selling the metal.) For example, back when gold was $20 an ounce, a $20 coin was made of an ounce of gold. Back when the size of the penny was first established, copper did not have as much value as it does today and a copper coin of that size was worth approximately a penny. Copper is worth much more now so it would cost much more than $.01 to produce a penny. Pennies are now mostly zinc with a very thin copper plating for appearance. Even so, given the costs of production (equipment, employees, transport), it still costs more to produce a penny than it's worth.
This is why there have been suggestions to eliminate the use of the penny.
We do not know. Copper was discovered before we had writing to keep records. People have used copper for about 6,000 years.
how to clean or treat copper pan before first use. Does it have some substance on it to keep it shiny that must be removed before use?
Silver, but they now make quarters out of copper and nickel so if you have a quarter that was made before 1965 keep it!!
you have to throw the flour away after a year.
Just keep using the very same schedule you were using before. I would also recommend you change the brake fluid at this time.Just keep using the very same schedule you were using before. I would also recommend you change the brake fluid at this time.
Yes you can. Keep them well covered otherwise they'll dry out and keep them refrigerated.
keep heat in copper is a good heat conductor.
The de-husk them before using them for the product.
If you don't it will tarnish.
If you're using copper or plastic pipe (pvc, abs, pex) then you don't have to worry about it. If you're using something ferrous, you'll need to keep the outsides lightly oiled.
hundreds of $$. I'm still looking for a price though so keep a hold of it until i can find a place with a price list for a Pennie that old.
PEX pipe will keep it hot longer than copper.
