The provided context from the search results does not contain specific information regarding the value of gold one-dollar coins. The text consists of website navigation and menus rather than descriptive content. Therefore, the following information is based on general numismatic knowledge.
The value of a "gold one-dollar coin" depends entirely on which specific coin is being referenced, as this description can apply to several distinct types. A primary distinction must be made between modern dollar coins with a golden color and historical coins actually composed of gold.
Modern U.S. dollar coins, such as the Sacagawea, Presidential, and American Innovation series, are often mistaken for gold. These coins are not made of gold but are composed of a copper core clad with manganese brass, which gives them their golden hue. For this reason, their value in circulated condition is typically just their face value of one dollar. Only uncirculated examples, special proof sets, or rare error coins from this series would carry a premium value for collectors.
Conversely, the United States Mint did produce genuine gold one-dollar coins from 1849 to 1889. The value of these historical coins is significant and is determined by two main factors: their bullion value and their numismatic value. The bullion value is based on the coin's gold content, which is approximately 0.048 troy ounces of 90% gold. However, their numismatic or collector value is almost always substantially higher. This value is influenced by the coin's rarity, which is determined by its year and mint mark, as well as its physical condition or grade. A common, circulated gold dollar from this era might be valued at a few hundred dollars, while rare, high-grade examples can be worth many thousands of dollars.
Finally, there are special modern commemorative or collector coins, such as the 2000-W Sacagawea dollar struck on a 22-karat gold planchet. These were not intended for circulation and are exceptionally rare and valuable, commanding very high prices at auction. For an accurate valuation of any specific coin, a professional appraisal is recommended.
