Proof coinage refers to special early samples of a coin issue, historically made for checking the dies and for archival purposes. In modern times, proofs are often struck in greater numbers, especially for coin collectors (numismatists). Nearly all countries have issued proof coinage.
The United States Bicentennial coinage is a set of circulating commemorative coins, consisting of a quarter, half dollar and dollar struck by the United States Mint in 1975 and 1976. Regardless of when struck, each coin bears the double date 1776–1976 on the normal obverses for the Washington quarter, Kennedy half dollar and Eisenhower dollar. No coins dated 1975 of any of the three denominations were minted.
The American Silver Eagle is the official silver bullion coin of the United States.

The Eisenhower Commemorative silver dollar is a United States commemorative coin minted in 1990 to celebrate the 100th Anniversary of the birth of General/President Dwight D. Eisenhower.

The West Point Mint is a U.S. Mint production and depository facility erected in 1937 near the U.S. Military Academy in West Point, New York, United States. As of 2019 the mint holds 22% of the United States' gold reserves, or approximately 54,000,000 troy ounces (1,700,000 kg). The mint at West Point is second only to the gold reserves held in secure storage at Fort Knox. Originally, the West Point Mint was called the West Point Bullion Depository. At one point it had the highest concentration of silver of any U.S. mint facility, and for 12 years produced circulating Lincoln cents. It has since minted mostly commemorative coins and stored gold.
The Library of Congress bimetallic eagle is a modern U.S. commemorative coin issued in the ten dollar denomination. It is the first gold and platinum bimetallic coin to be issued by the United States Mint. It was issued in proof and business strike qualities.
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 follows the design of the Indian Head nickel and has gained its nickname from the American Bison on the reverse side of the design. This was the first time the United States government minted pure (.9999) 24-karat gold coins for the public. 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.

One of the most profitable aspects of the Royal Canadian Mint (RCM) is its numismatic product line. The first numismatic coin from the RCM was arguably the 1935 dollar commemorating the Silver Jubilee of King George V. Though intended for circulation, it was the first Canadian coin commemorating an event. The decision to issue this coin was made in October 1934 by Prime Minister R. B. Bennett. There were economic and patriotic motivations for the release of a silver dollar, including a hope to boost the silver mining industry. In future years, the silver dollar would have a more emotional meaning for many Canadians because it was also the first coin to have the Voyageur motif on its reverse.
Since the 1976 Summer Olympics in Montreal, the Royal Canadian Mint has struck Summer and Winter Olympic coins to mark Games held in Canada.
Although the first Olympic coin can be traced back to 480 BC, the modern Olympics did not see its first commemoratives until 1951. The original concept of Olympic coins was that the Greeks believed that coins brought the general public closer to the Olympic games. The premise was that those who could not attend the games could at least have a tangible souvenir of the event.
Traditionally, Olympic coins are numismatic coins. However, several host countries minted so many coins – particularly silver ones – that their value has become just slightly above the value of their metal content. Coins for the 1976 Montreal, 1984 Los Angeles, and 1988 Seoul are generally considered to fall into that category.
The Royal Canadian Mint has made coins with various themes. Most recently, ice hockey has been used for many numismatic releases. The first known ice hockey coin was for the 1988 Winter Olympics. Issued on February 25, 1986, the coin featured a goalie on the coin. Edge lettering was also used for the coin, the first time that it was used on silver coins.
The 5,000 yen coin is a denomination of the Japanese yen used only for commemoratives struck by the Japan Mint. These are made only for collectors who purchase them directly from the mint at a premium. 5000 yen commemorative coins have historically been struck in a silver alloy since 1990. This practice changed in 2021 when gold was used for the first time for a coin celebrating 150 years of Japan's modern currency system. Measurements for the coins in terms of width and weight have remained the same except for the gold issue when these were lowered. Earlier coins were also once struck in the millions before the alloy change took place.
The double sovereign is a gold coin of the United Kingdom with a face value of two pounds sterling (£2). Rarely issued in the first 150 years after its debut in 1820, it never had a significant presence in circulation. It became a collector and bullion coin, and has been struck most years since 1980. It features the reigning monarch on its obverse and, most often, Benedetto Pistrucci's depiction of Saint George and the Dragon on the reverse.
