.....1 cent. It is in common circulation and is made out of copper-plated zinc. It isn't worth anything more than face value.
It depends what you are asking. Assuming that you are referring to US One Cent Coins:the face value is US$25.00the metal value of the copper in pre-1982 coins is US$67.35 (as of June 8, 2011), although it is illegal to melt them down for copperthe metal value of the zinc in post-1982 coins is US$15.15 (as of June 8, 2011)the numismatic value depend on the year, mintmark, and condition of each coin
It's probably only worth face value, except as a conversation piece / curiosity. All US pennies since 1983 are made almost entirely of zinc, covered with a thin coating of copper. If the coating was never applied at the mint, or someone dipped the coin in acid the silver-colored zinc core will become visible. No circulating US coins have contained any silver since 1969, and pennies were never made of silver because they would have been worth more than dimes.
There's no such thing as a "white penny". Cents are made of zinc and plated with copper. You have either a cent ... - that's been plated a second time for use in jewelry or similar. Value, 1 cent. - that's been dipped in acid to remove the plating. Again, 1 cent. - that was accidentally missed during the plating phase. That's a real mint error and is worth $75 or so, but you'd need to have the coin evaluated in person by a dealer or appraiser who is familiar with error coins.
The coin is zinc coated steel, not silver, that's why it's magnetic. 1943 steel Lincoln cents are common. Most circulated coins have retail values of 5 to 10 cents.
One of the many types of brass.
Muntz metal (see link).
A modern penny contains 2.5% zinc by weight, while the rest is made up of copper.
pure metal is a single element as Iron,copper,gold,silver while alloy is a mixture of two or more metals as Brass contains copper and zinc,Bronze contains copper and tin.
Alloys that contain only copper and zinc are usually called "brass"; there are also some alloys that contain one or more other metals in addition to copper and zinc, and these usually have another name.
Most trumpets are made of brass. They are then dipped in lacquer to maintain the shine. However, The most common type of brass used is yellow brass, which is 70 percent copper and 30 percent zinc. Other types include gold brass (80 percent copper and 20 percent zinc), and silver brass (made from copper, zinc, and nickel).
When a piece of copper metal is placed in zinc sulfate solution, nothing happens because copper is lower in the reactivity series than zinc. This means that zinc is more reactive than copper and will displace copper in the solution, resulting in the formation of zinc metal and copper sulfate.
there are many combinations of brass/copper/zinc. High brass for example has 65% copper and 35% zinc. Nickel brass has 70% copper and 24.5% zinc with 5.5% nickel Prince's has 75% copper and 25% zinc
The melting point of gilding metal is between 427 and 788 degrees Celsius. Gilding metal is an alloy that is comprised of 95 percent copper and 5 percent zinc.
Zinc is more reactive than copper sulfate. When zinc is placed in a solution of copper sulfate, a displacement reaction occurs where zinc displaces copper from the solution, forming zinc sulfate and copper metal.
When copper metal is reacted with concentrated nitric acid, it undergoes an oxidation reaction to form copper(II) nitrate, nitrogen dioxide gas, and water. When zinc metal is reacted with concentrated sulfuric acid, a displacement reaction occurs to form zinc sulfate and hydrogen gas. When a potassium chloride solution is reacted with zinc powder, a single displacement reaction takes place to form zinc chloride solution and potassium metal.
The Liberty Bell is composed primarily of Copper. Approximately 70 percent copper, 25 percent tin and traces of lead, zinc, arsenic, gold and silver.
