The last year for 100% pure copper cents was 1857.
1983 to date the percentage of copper is .025%
Over a million dollars if it is genuine. However, the vast majority of "copper" 1943 pennies are simply genuine copper pennies of later dates with their date modified to read 1943 or 1943 steel pennies with a thin layer of copper.
Over a million dollars if it is genuine. However, there are only a handful of known genuine 1943 copper pennies. Many "copper" 1943 pennies are either genuine 1943 cents dipped in copper to make them appear to be copper (but will still stick to a magnet due to the steel) or other years of wheat pennies with the date altered to make it look like a 1943 penny, however, experienced coin dealers and graders will be able to spot these as altered dates.
A rare date for wheat pennies would be 1909 S VDB.
So far at least 10, and possibly 12, genuine 1943 copper cents have been authenticated. Because these were struck in error (leftover copper blanks intended for 1942 cents got mixed in with steel blanks being struck with the 1943 date) the exact number is unknown. It's about 99.99999% certain that none are left in circulation.
1983 to date the percentage of copper is .025%
Lincoln cents from 1982 to date are 99.2% Zinc & 0.8% copper.

1982 to date are 99.2% zinc & 0.8% copper
You can tell if a penny is made out of zinc or copper by the date on the penny. If the date is before 1982 then the penny is 95% copper. Pennies dated 1983 or later are 97.5% zinc with a thin copper coating.
It depends on what year they were minted but from 1982 to date Lincoln cents are made from .975% zinc & .025% copper.
Copper pennies are worth at least 2 cents for their copper content. Without knowing details such as the date, mint mark (if applicable), and condition, there is absolutely no way to give a more specific answer.
I would be impossible to give a value for all copper pennies. The only pennies made of mostly copper are those made before 1983. These have a melt value of 2 cents. To find the value of an individual coin ask another question structuring it like the one below(be sure to fill in the <> with the correct information): What is the value of a <date> <country of origin> <denomination>
Between changing the composition of the US one-cent coin (often referred to as a "penny," even though the word has never appeared on the US coin) and experimenting with the size of the date, there are 7 different types of 1982 pennies: * 1982 copper, small date * 1982-D copper, small date * 1982 copper, large date * 1982-D copper, large date * 1982 copper-plated zinc * 1982-D copper-plated zinc * 1982-S copper proof It's easy to tell between the different mint marks; just look below the date. The plated zinc cents are slightly lighter, and don't give the distinctive "ring" of a copper (actually a copper-zinc alloy) cent. The only way to tell between the date sizes is to study pictures of the two, and notice the distinctions in how they look. Note that there was only one proof type, minted only in San Francisco.

From 1982 to date all Lincoln pennies are copper plated zinc, the 1993-D is just a penny.
