Gold is a heavy element commonly used in coins and jewelry due to its luster, rarity, and resistance to tarnishing and corrosion.
Roman coins came in gold, silver and copper. In the earlier days there were also coins in bronze and brass.
It is used for gold coins, gold blocks and sun block.
If you mean a Sacagawea or Presidential dollar, it has no gold and is worth $1.00. The U.S. has not used any gold coins for circulation since 1933.
The ones that were actually used for money before 1933 were 90% gold. The modern bullion coins are 91.675 gold, 3% silver, and 5.33% copper.
Due to a shortage of blanks used to make the coins none were produced. NOTE: The coins are referred to as American Eagle Gold Bullion Coins not walking liberty gold pieces.
