All 2010 US nickels were struck in the standard cupronickel alloy. A nickel that appears to be made of copper could have been discolored by heat or chemical exposure, or it might be copper-plated. The latter is a very common high-school chemistry experiment.
If you have a US nickel, it is either coated with copper or has changed color due to exposure to some chemical and has no special value. If it is a 1942 Canadian nickel, it varies from $.40 to $1.75 in circulated conditions, $3 and up in uncirculated grades. The material is called "tombac" and is an alloy of copper and zinc.
Almost certainly 5 cents. US nickels don't have enough copper in them to look copper-colored. Your coin is most likely discolored due to exposure to heat, chemicals, or other contaminants.
The US government (if you count production as buying them), coin collectors, and speculators on the value of copper and nickel (although defacing US currency is a criminal offense).
Do you mean copper? If so, all US nickels except the War Nickels (1942-1945) are made from 75% copper and 25% nickel. Your 1999 is just a nickel.
It's brand new and has no extra value unless you have a proof or uncirculated coin. Those might be worth a quarter or 30 cents.

The first 5-cent US nickel was made in 1866, the 3-cent nickel in 1865, and the copper-nickel flying eagle 1-cent in 1856.
All US nickels (except for silver war nickels) are 75% copper and 25% nickel, with a present melt value of 4.9 cents.
The color of a US nickel is silverish. US nickels are actually made of 75% copper, but the silvery color of the remaining nickel 25% predominates.
25 cents. All 1974 quarters were made from copper-nickel.
No such (US) coin exists because the copper-nickel 3 cent piece was not minted until 1865.
As of September 2021, the metal value in a nickel (which is composed of 75% copper and 25% nickel) is less than its face value. The cost of the metals used in a nickel is lower than 5 cents due to fluctuations in metal prices.
A US quarter is primarily made of nickel and copper. It is composed of approximately 91.67% copper and 8.33% nickel.
As of 07/2010 a proof set containing copper-nickel clad coins retails for about $13, while a Prestige set with silver coins sells for about $35.
The only US coin ever struck in steel was the famous 1943 Lincoln cent, minted when copper was diverted to making ammunition. All buffalo nickels are made of an alloy of 75% copper and 25% nickel. Please see the question "What is the value of a 1927 US nickel?" for more information.

US state quarters are made of a combination of copper-nickel (75% copper, 25% nickel) bonded to a copper core. This composition helps to create a durable coin that is resistant to wear and maintains its appearance for circulation.
