The Seated Liberty dollar was a dollar coin struck by the United States Mint from 1840 to 1873 and designed by its chief engraver, Christian Gobrecht. It was the last silver coin of that denomination to be struck before passage of the Coinage Act of 1873, which temporarily ended production of the silver dollar for American commerce. The coin's obverse is based on that of the Gobrecht dollar, which had been minted experimentally from 1836 to 1839. However, the soaring eagle used on the reverse of the Gobrecht dollar was not used; instead, the United States Mint (Mint) used a heraldic eagle, based on a design by late Mint Chief Engraver John Reich first utilized on coins in 1807.

They have legal tender status in Australia and are one of few legal tender bullion gold coins to change their design every year, another being the Chinese Gold Panda. This and their limited annual mintage may, unlike for many other bullion coins, raise their numismatic value over the value of gold used.

The American Buffalo, also known as a gold buffalo, is a 24-karat bullion coin first offered for sale by the United States Mint in 2006.

The coin contains one-troy ounce (31.1g) of pure gold and has a legal tender (face) value of US$50. Due to a combination of the coin's popularity and the increase in the price of gold the coin's value has increased considerably. The initial 2006 U.S. Mint price of the proof coin was $800. In 2007 the price was $899.95, $1,410 in 2009, and $2,010 in 2011.
The Silver Kookaburra is a silver bullion coin originating from Australia, and produced at the Perth Mint starting in 1990.

While the obverse of the coin always depicts Queen Elizabeth II, the reverse side changes every year, always featuring a kookaburra, a bird native to Australia. Due to the yearly design change and limited production of the one-ounce coins, they have higher collectible value than some other bullion coins. The Perth Mint generally ships the coins in individual plastic capsules. One-ounce coins ship in shrink wrap rolls of 20, with 5 rolls in each box of 100. They are minted in four sizes; 1000g, 10, 2 and 1 troy ounces.
