US one dollar gold coins were last made 1889. Make sure you used the correct date. If your coin has a different date ask another question like the one above but substitute the date with the date on your coin.
for money
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.
1933 was the last date for circulating gold coins in the US. The US went off the gold standard in 1933 as a step in ending the Great Depression. The mints had already struck quantities of gold coins with that date and some were released to circulation before the government recalled them, but most were melted. Because of that melting, 1933-dated gold coins are prized. For example only ten 1933-dated double eagles are known to have survived and they are conservatively valued at several million dollars apiece. An actual market value is unknown because the coins are technically illegal to be owned privately, though. Modern gold coins are sold for investment and collecting only. Even though they carry artificial denominations their actual value is based on their metal content; it would be extremely foolish to try to spend one.
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.
