When was Last copper cent mint date?
The last copper (actually bronze) cents were made in mid-1982. The mints gradually changed over to copper-plated zinc as the remaining stocks of bronze blanks were used up.
How do you know if a penny is copper or bronze?
The easy way is by the date. 1909 to 1958 (except the 1943 steel coins) are bronze. 1959 to 1981 are a copper alloy that technically is not bronze. 1982 was the transition year from a copper alloy to the zinc cents we now have. Coins of both compositions exist only for 1982 dated coins. 1983 to date are zinc.
How can you tell if your 1869 Indian Head Penny is copper-nickel or if it is Bronze?
If it was minted in 1981 or before [except for 1943 which were made from steel] it is bronze. In 1982 some were made of bronze and some were made of copper clad zinc. The copper clad zinc cents are lighter than the bronze cents. You can weigh them to tell the difference. Also, if you drop them on a hard surface, the bronze cent will have a greater metallic ring to it than the zinc cent. Bronze cents look a little different in color too. While not a foolproof way to tell, most seem to have a slightly darker appearance than the zinc cents. This is because the plating on the zinc cents is pure copper and the bronze cents are not pure copper and thus have a slight difference in color usually.
What is the value of a copper US cent?
That's an incredibly broad question because US cents ("pennies") were made of copper from 1793 to 1857, copper-nickel from 1857 to 1864, and bronze (95% copper) from 1864 to 1942 and 1944 to mid-1982. On top of that they were made at 3 different mints, so there are many hundreds of possibilities to choose from. Please post a new question with the coin's specific date. If you word the question as "What is the value of a (date) US cent?" (where 'date' is the coin's date, obviously) you should be taken to a full answer.

Were any pennies minted that were not copper?
1943 cents were made out of scrap steel coated with zinc because copper was needed to make ammunition. A few bronze blanks left over from 1942 were accidentally mixed in with the steel blanks and were struck with a 1943 date. These errors are extremely rare and are worth tens of thousands of dollars at a minimum. Bronze cents were resumed in 1944 but a few leftover steel blanks were similarly struck with a 1944 date.
How do you tell the difference between a zinc and bronze penny?
A bronze penny has a reddish-brown color due to its copper content, while a zinc penny has a silver appearance. You can also check the date on the penny, as pennies made before 1982 are bronze and those made after are zinc.

Assuming you mean a US cent, in general if its date is 1981 or older, it is predominantly copper. The major exception would be 1943 cents that were made of zinc-plated steel due to wartime shortages. 1982 cents were struck in both zinc and bronze so you need to weigh them - a bronze cent weighs about 3.1 gm while a zinc one weighs 2.5 gm.
