An uncirculated coin is a coin that is made to specs for circulation but has never actually been used as money. As a result, it has no visible signs of wear, meaning it is in excellent condition. A set of uncirculated coins contains at least one of every denomination from each of the mints. The exception to this is from 1947 to 1958 when the uncirculated coin sets contained two of each denomination. Since 1947, the Treasury Department has been packaging and selling sets of uncirculated coins. Coin collectors are particularly interested in these sets, since these unusual coins are a great way to add to their investment. Keep in mind that each uncirculated coin can have a different grade or condition rating. In perfect condition, with no traces of scratches, contact with other coins, or handling, an uncirculated coin is considered an MS-70 (mint state perfect). Other grades for an uncirculated coin include an MS-60, which may have a few contact marks or lack some of the original luster; however, it will have no traces of wear. An AU-50 is an uncirculated coin with evidence of light wear with at least half of the luster still present. A reputable coin dealer can authenticate the condition of an uncirculated coin set whether you are buying or selling. The newer uncirculated coin sets by the United States Mint has the new satin finish to give consistency for all United States Mint uncirculated products. This finish makes it easy to determine the difference in the United States Mint uncirculated coin sets and those coins in rolls or bags that have never been circulated. |
