The Mint struck special versions of the 2009 Lincoln Bicentennial cents using the same bronze alloy as the original 1909 coins. However these were only sold to collectors and not put into circulation.
It's unlikely but always possible that someone spent one of these special coins. The best way to tell it from a standard circulation cent would be to weigh it on a sensitive scale. A 2009 bronze cent minted in the 1909 alloy would weigh 3.11 gm while a 2009 cent struck in the current copper-plated zinc composition would weigh 2.5 gm.
i don't know............. maybe copper (not sure)
Copper oxide is not an alkaline but it is a base
Conductor, which is why it's used for wires.
i would like to know about the making process of cyanide copper salt
Copper-nickel is an alloy of copper and nickel which have different densities. You need to know the proportions of each metal in the alloy to determine its density.
The 1857 large cents were the last one cent coins made of pure copper. The simple answer is: All Lincoln cents from 1909 to 1981 are mostly copper. 1982 is the year they changed the composition to zinc from copper. 1983 to 2011 Lincoln cents are zinc.

No additional authenticated 1943 cents have turned up in the last 25 years or so.A genuine 1943 copper cent:> will not stick to a magnet.> has a date where the bottom loop of the "3" is elongated rather than circular> weighs 3.11 gm> has smooth metal on the flat surfaces of the coin.If it appears to be copper but sticks to a magnet it's a regular steel cent that has been plated.If the bottom loop of the 3 is round, it's a 1948 cent that has been altered to make a crude counterfeit.If the flat parts of the design are somewhat pitted you have a copy, again a counterfeit.If it weighs much more or less than 3.11 gm it's also a fake.If it passes all of these tests you should have it examined in person.If you mean a 1943 Lincoln cent struck on a copper planchet, authentic coins are valued at $50,000.00 or more.
Pre 1982 and some 1982 cent coins are mostly copper. Copper is a commodity traded on a daily basis si the actual price changes daily. An old copper penny has about 3 cents of copper in it, but before you rush down to melt all those copper cents you need to know that congress by law has made it isillegalto do so.
i know they were made from 1909-1959, and contain a valuable 95% copper. some people melt pennies and turn them into ''copper nuggets'' because the metal used for a coin is worth more than 1 cent

About a third of a cent US, since a pre-1982 penny has a mass of slightly over 3 grams and is about 95% copper (the remainder is zinc). Many of these pennies are still in circulation.
This is nearly impossible to answer without any clarification.As far as I know, the first country to use a "cent" (as in, just plain cent and not the translation of cent in say, French) is the US which featured a personification of Liberty on all cents up until 1909 when it was replaced by Lincoln. But, naturally that is not a real person.Most likely the first instance of a real person on a "cent" (again, just a plain cent and not the transliteration of a cent) would be Queen Victoria since she reigned in Canada which had a cent.
For me to relay to you the value of a coin, I will need to know the following: 1. the year in which the coin was minted 2. the mint mark and 3. the mint state.
No, Lincoln Heights concluded after its fourth season, which aired from 2009-2010. There are no plans for a fifth season.
copper is a metal.
We do not know. Copper was discovered before we had writing to keep records. People have used copper for about 6,000 years.
