None. The coins are made of copper-nickel for circulation, while some "Prestige" proof versions are struck in silver.
NO circulating US Coins since 1933 have contained any gold, including the so-called "golden" dollars that are really just brass (copper, zinc, manganese, nickel).
Even when the Mint did strike gold coins for circulation the lowest denomination was $1, although some private mints did make smaller denominations.
You may be thinking of the many companies that take sets of state quarters, gold plate them, and sell them as "instant collectibles". Some collectors of novelty items may pay a premium for a full set of these coins but they have no extra numismatic (= coin collector) value because they're classed as altered coins.
$1 coins were struck in a 90% gold alloy during the years 1849 to 1889. Weights varied slightly but averaged 1.7 gm, so they contained about 1.53 gm of pure gold.
Of course modern "golden" $1 coins are made of manganese-brass so they have no precious metals in them. In fact, the metal in a current $1 coin is only worth 10 or 15 cents.
A US gold dollar minted from 1849 to 1889 contains 1.672 grams (.04837 oz) of gold. However, the collector value of the coins (since many were lost or melted down during gold confiscation in the 1930s) is much, much higher than the small gold content would lead you to believe.
Modern "golden" dollars minted since 2000 are actually brass, and don't contain any gold at all.
U.S. nickels have never been made of gold, nor were any coins of any denomination by the 1960s. All you have is a gold-plated nickel, only worth as much as someone on eBay is willing to spend (which won't be much).
If you mean a one dollar gold coin dated from 1849 to 1889 it is 90% gold and 10% copper. No other US one dollar coins after 1889 contain any gold.
