The Saint-Gaudens double eagle is a twenty-dollar gold coin, or double eagle, produced by the United States Mint from 1907 to 1933. The coin is named after its designer, the sculptor Augustus Saint-Gaudens, who designed the obverse and reverse. It is considered by many to be the most beautiful of U.S. coins.

Though called the “Indian Head Gold Eagle”, the obverse design is not actually that of an American Indian but of Lady Liberty facing to the left wearing an indian headdress or feather war bonnet with “LIBERTY” inscribed on the headband of the bonnet.

Above the bust design are 13 stars to represent the original states or colonies. The reverse features a standing eagle on a perch of bundled arrows and an olive branch.

First struck in 1908, Indian Head $5 gold half-eagles, along with their Indian Head $2.50 gold quarter-eagle brethren, are perhaps the most unique and fascinating coins ever minted in the United States.

Unlike any other modern coins, these Indian Head gold coins feature an incuse design, meaning their images and inscriptions are actually cut into the coin surface. All other U.S. coins, before and since, are struck in bas-relief, meaning their designs are raised slightly above the surface fields.

First struck in 1908, Indian Head $2.50 gold quarter-eagles are perhaps the most unique and fascinating coins ever minted in the United States. The artistry of the coin design was condemned by some collectors and defended by others.

Because of their unique design and unusual history, $2.50 Indian Head gold coins, are highly prized by collectors and remain in constant demand.

The twenty-dollar Liberty Head Gold Double Eagle (or simply $20 Liberty) was first minted for circulation in 1850 (one $20 Liberty was minted in 1849, it resides in the Smithsonian). A total of 1,311,261 gold Libertys were produced that first year - 141,000 in New Orleans and the remainder in Philadelphia.

Designed by James Longacre, the $20 Liberty gold double eagle was one of the few U.S. coins produced by five different U.S. Mints (the Morgan silver dollar was another) over its "mint life".

Designed by Christian Gobrecht, the $10 Liberty Head was produced continuously from 1838 to 1907 with each coin containing just under a ½ ounce of gold.

The obverse design features an idealized bust image of Lady Liberty facing left wearing a coronet with “LIBERTY” inscribed. Above the bust design are 13 stars to represent the original states or colonies.

Designed by Christian Gobrecht, the $5 Liberty Head ½ Eagle was produced continuously from 1839 to 1908 with each coin containing just under a ¼ ounce of gold.

The obverse design features an idealized bust image of Lady Liberty facing left wearing a coronet with “LIBERTY” inscribed. Above the bust design are 13 stars to represent the original states or colonies.

The $2.5 Liberty Head, or ‘Liberty Head Quarter Eagles’ gold coin was designed to look very similar to the $10 and $20 Liberty Heads. The obverse side of the coin contains an image of Lady Liberty with her hair in a bun and wearing a coronet inscribed with the word liberty.

She is also surrounded with 13 stars which represent the 13 original colonies. The reverse side of the coin has the American Eagle with its head tilted sideways holding an olive branch in one claw and arrows in the other.

British Sovereigns were first minted in 1498 and eventually set the standard for gold coins in both England and the United States. The purity of these coins is set at 22 carats, or about %91.67 gold. British Sovereigns, which are still being minted today, are also available as bullion.

Minted from 1871 to 1898, French 20 Franc Angels have a lot of history behind them, making them a very unique addition to the European coin collection. Sometimes called the “Guardian Angel”, these coins were supposedly lucky charms; so lucky, in fact, that during World War I, French pilots rarely took flight.

The French 20 Franc “Rooster” gets its name from the image of a Gallic Rooster, or Coq Gaulois, which has been one of the national symbols of France since the Middle Ages.

French Roosters, which are considered private gold, are one of the most popular European gold coins due to their high availability. These coins were minted from 1899 to 1914.

French 20 Franc Napoleon III coins, which were minted from 1852 to 1870, were not only minted in France. These coins, often referred to simply as “Napoleons”, were also minted in Italian territories, Swiss territories, and in the Netherlands when France occupied these areas.

During the chaotic 19th and 20th centuries, French investors were known to store Napoleons as a hedge against the possibilities of war and the deterioration of currency. Uncirculated Napoleons are exceptionally rare and bring high value.

The Swiss 20 Franc Helvetia, which has been given the nickname “Swiss Miss”, has an outstanding reputation for maintaining its value, due to its association with the stability and strength of the Swiss economy. These coins were minted at the Swiss National Mint starting in 1897 and are 90% pure.
