All 1948 US nickels (in fact, all US nickels except those made during WWII) are struck in an alloy of 25% nickel and 75% copper, so their standard color is silver-gray.
If a nickel was exposed to heat, chemicals, or some similar agent it may take on a different color. Nickels are also popular coins for high-school chemistry experiments.
IT wouldn't look like anything. The first nickels weren't minted until 1866 and the first buffalo nickels came out in 1913.
The Lincoln cents dated 1943 were struck on zinc coated steel planchet not copper. It may look like copper and could be plated.Test it with a magnet to see if it sticks to it. If it does not react to a magnet look at the 3 in the date. Many 1948 cents have been altered so the 8 looks like a 3. So it's Best to have a dealer or collector look at the coin.

Except for minor differences in early 1883 issues, all Liberty nickels used the same design. Please see the Related Link for an image (note that the color of the picture is due to toning - when new, Liberty nickels were exactly the same color as current Jefferson nickels.)
It has the same overall design as US nickels minted from 1938 to 2003, with Thomas Jefferson facing left on the front and an image of his house, Monticello, on the back. The 2 major differences are that the coin is a somewhat different color than standard nickels and it has a large mint mark (P, D, or S) over Monticello's dome. The reason is that from late 1942 to 1945, US nickels were made of a special alloy of copper, silver, and manganese because nickel was needed for the war effort. To distinguish these from other nickels the mint mark position was moved, and a "P" was used for the first time on any Philadelphia-minted US coin.
It wouldn't look like anything because there aren't any silver 1957 US nickels. Except for special "war nickels" made from late 1942 to 1945, all US nickels are made of the same alloy of 25% nickel and 75% copper. War nickels were made of an alloy of 56% copper, 35% silver, and 9% manganese because nickel metal was needed for the war effort. These coins are distinguished by a large mint mark letter over the dome of Monticello on the back.
To clear things up, 1941 nickels aren't war nickels. The US didn't enter WWII until December of that year, and war nickel production didn't start until 10 months later. All 1941 nickels were struck in the standard alloy of 75% copper and 25% nickel, so a copper-colored coin could result from exposure to heat or chemicals. In particular, nickels are often copper-plated in high-school chemistry experiments.

No. If you have one, the most likely case is that it's a normal nickel* that someone plated. In that case it'll weigh just about the same amount as a normal nickel. The other and less likely possibility is that it was struck on a planchet (blank) intended for a foreign coin. In that case it will almost certainly weigh a different amount. You'd need to have it examined in person by a dealer or other expert. (*) I had to change your question so it would show up correctly in searches. The coin is a nickEL rather than a nickLE.
Copper and gold look similar, but while gold is yellowish, copper is reddish.

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.
no.
Greenish - blue, like (almost) all copper compounds.
Articles made of gold may be plated with copper ( copper electroplating ). The article will look like copper .
Copper oxide appears as a black or dark brown powder after copper has burned.
