Believe it or not, an "eagle" is an official coin denomination, worth $10. It's a holdover from an early plan to have coin denominations in multiples of 10 rather than 100. So, a $2.50 gold piece is a quarter-eagle, $5 is a half-eagle, $10 is an eagle and is $20 a double eagle.
$1 and $3 gold coins (struck to facilitate the purchase of stamps) didn't have special names, and an experimental $4 denomination was called a "stella" because it had a star-shaped pattern on the back.
FWIW, there was even a plan for a $100 denomination called a "union", so the few $50 coins ever minted were sometimes called half-unions.

1932 was the last year gold coins were struck for circulation.

California fractional gold coins are tokens struck in California to make up for the lack of US small denomination coins in the western US. During the early gold rushes, there was no nearby US mint in the west, and there was an abundance of gold. So people used the US gold standard price ($20.67 per troy ounce, since the US dollar was on a gold standard) and made coins with the required amount of gold to make up for small change. These coins are today very collectible, however, fakes abound and there is little information about them online.
