A majority of coins that are gold, such as the $1 USD coin, are gold plated clad.
Clad coins are generically nickel, zinc, copper, and manganese.
The coins are made out of metals that are lesser in value than the face value of the coin at the date of printing. (Except the penny, there are no metals cheap enough)
The gold plating on them is not very thick (not even a mm thick) and usually not a 24 karat.
However, there are refineries that do mint solid gold coins in varying karats. So if you are in a coin shop and they are selling gold coins that are "new" you are looking 99.99% pure gold. Which is 24 karat gold. This will value at the current spot value. (But will cost you more than spot to purchase due to mark up at the store)
A Different Answer:
The United States dollar coins minted since 2000 contain no gold, not even a thin plating. The name "Golden Dollar" is misleading but in reality the coins are primarily brass throughout with a little manganese and nickel mixed in. They are not a true clad coin in which a core metal, usually copper or an alloy of copper is covered with a layer of another metal and then the blanks for the coins are stamped from it. This is why you can see a little copper color on the outer edges of the coin. Current Lincoln Cents us a core metal of zinc with a plating of copper over it. You can not see the zinc on the edge of a penny.
Private mints may produce gold plated coins, and probably do, but the U.S. Mint has never produced a gold plated coin.

Silver dollar coins (1794-1935) were never made of pure silver. It's too soft and the coins would wear out very quickly. They (and most other silver US coins) were made of an alloy of 90% silver and 10% copper. Circulating US dollar coins were made of copper-nickel from 1971 to 1999. The composition was changed to gold-toned brass in 2000. Modern "eagle" coins with an artificial $1 denomination are made of 99.9% pure silver, but these coins aren't intended for spending.
Gold, silver, and platinum have been called "precious metals" because they are metals and were used to make coins (money) in the days when money had to be made of something that was considered to be valuable in themselves. Thus, as coins they were valuable or precious
