In the year 1892, Congress authorized the making of commemorative coins that celebrate and honor American people, places, events, and institutions. Along with commemorating important aspects of American history, these coins also help to raise money for many important causes. Part of the price of these unique coins is in fact a surcharge that goes to the organizations and projects that benefit the community. The aspects of charity and community really make these coins something special. These special coins are in fact legal tender, but they are not minted with circulation in mind. Each and every commemorative coin is produced by the United States Mint.
Proof sets are a well known and common item for collectors everywhere. There are also silver proof sets, specifically for silver coins, as you would expect. Proof sets containing silver started in 1936 and were made till around 1964, when the silver content in all coins, not just proof sets, were slowly reduced to nothing. Proof sets continued to be made, but could not strictly be called silver proof sets. That is until 1992 when the demand became great enough that Silver Proof Sets were made. These Silver Proof Sets are a sought after item for many collectors.
With every edition of coins that circulate there is usually a special set of those coins that aren’t meant to be in circulation, or in reality, for the use of day to day commerce at all. These unique coins are known as “proof sets”, and are mostly meant for the purpose of collection. They look different from the other coins as well, and not just the worn coins you may have in your pocket. Proof sets also look markedly different from uncirculated coins that have high MS grades. The reason that the proof sets look different is quite literally because they are made using a different process than their run of the mill counterparts.
Throughout the history of the United States, there have been many splendid gold coins that have been minted and circulated until gold coins were discontinued in 1933. In 1986, the United States decided to once again start minting Gold coins. They started with perhaps the most popular modern gold coin: the American Gold Eagle. The American Gold Eagle comes in denominations of $5, $10, $25, $50. The obverse has a glorious Augustus Saint-Gaudens rendition of lady liberty clutching an olive branch in her left hand and a torch in her right, with the capitol building in the left background.
CAC was founded in 2007, and they evaluate certain coins that have already been certified by either PCGS or NGC. This further ensures the quality of the coin, and often raises its value. CAC places specific stickers on the coins they evaluate that denotes their grading and value. CAC also provides a serial number that provides security for coin holders.
