US error coins are error coins produced by the US government, dating hammered coins. There are three categories of error coins as provided by the American Numismatic Association. Metal usage and striking errors referred to widely as planchet errors, dating hammered coins, die errors, and mint striking errors.
This does not include the varieties that the US Mint has issued over the years. Since the inception of coin collecting there has been much dating hammered coins over what constitutes a true mint error. An organization of coin collectors named the Combined Organizations of Numismatic Error Collectors of America CONECA was created that specifically deals with mint errors, dating hammered coins.
A planchet is produced by punching blanks in sheet metal stock specially made for the types of mint blanks required. After the blanks are punched they are rolled on the edge placing an upset needed for the minting process.
The blanks are then washed and annealed making them ready for the minting process. There are several types of planchet errors that include: improper alloy, wrong stock, imperfect blank, and lamination. A planchet error may be caused by an improper alloy mixture. Improper alloy mixtures occur when the sheet stock contains uneven layers of the metals intended for the type of coin that is produced, dating hammered coins.
A result of improper layers of metals is a coin produced without an intended surface layer of nickel. A dime or quarter without the nickel layer will contain only the copper alloy mixture.
A planchet error can be caused by using a blank intended for a different denomination or wrong stock. The result of using a blank intended for another denomination is the minting of the intended obverse and reverse on the wrong stock. A planchet error also refers to many types of issues where an imperfect blank has been used. Pieces of the blank might be missing causing a half moon to be missing from the coin.
Collectors denote missing parts of the planchet as "clipped planchets, dating hammered coins. A piece of debris may find its way into the dies causing a series of lines to be minted on the surface of the coin. A planchet dating hammered coins be in a state that causes peeling on the surface of the coin, dating hammered coins. The peeling of any part of the surface of a coin is known as a lamination error.
Die errors are caused by the mint dies wearing down over time or dies that have not been prepared identical to others that have been replaced. The result dating hammered coins preparing a set of new dies improperly from the original hub results in coin errors such as doubling, dating hammered coins, extra details, or missing details on the surface of the coin.
A die break is caused when the mint die suffers a crack and this crack feature is transposed onto the coins in the minting process. Coins minted with a die break have a thin line or lines that are raised running across the surface of the coin. Below is a photograph of a S Jefferson nickel with a die crack along the top of the portrait of Jefferson.
A die break can create coins that have deep impressions in a coin that is filled in with metal. The coin shows a raised patch of metal were the brake occurred. This type of error is commonly known as a "cud" error. Gouges in coins caused by flaws in dies, and die polishing mistakes resulting in coins minted with surface indentations, dating hammered coins, or polishing lines. Dies that are damaged and used in the minting process also create errors resulting in dating hammered coins having die chips embedded in the surface of the dating hammered coins. A die clash occurs when a planchet is not fed into the collar that holds the coin in place for the minting process.
The two dies meet and each carries away part of the design embedded on the die. Coins minted using these dies cause coins to be minted with parts of the reverse design on the obverse or parts of the obverse on the reverse of the coin.
Die rotations cause coins to be minted with the reverse or obverse of the coin partially or fully dating hammered coins. A die rotation occurs when the dies become loose and they then turn. When a mint worker polishes a die to remove a die clash or some other defect there may be instances where a part of the design is removed. The 3-legged Buffalo nickel was the direct result of die polishing and the removal of a leg.
The Lincoln cent with the raised 7 is also the result of die polishing. Beforeall US coin dies were subject to mint mark errors resulting from the preparation of the dies. The mint mark was hammered into the die manually sometimes causing a die to have a doubling, dating hammered coins.
In the minting process this would create a series of coins with a distinct dating hammered coins slight doubling of the mint mark. Double die coins are mainly created by a defective hub which is used to create many dies for the minting process. Collectors classify double dies as DDO double die obverse coinsDDR double die reverse and OMM over mint mark. The over mint mark is created when a one date and mint mark is punched over another date, part of a date, or mint mark.
These coins are generally restricted to the early minting process of coins dating before the turn of the century. The DDO and DDR errors are related to any part of the coin that shows a dating hammered coins doubling.
Pictured below is a S double die Lincoln cent. Collectors and organizations dedicated to collecting coins regard mint striking errors as those that have been created by the minting process.
Mint striking errors are caused by the collar moving, cracking, or not being present in the minting process. The collar is a third die that actually holds the coin in place in the minting process. It is the collar that imprints the lettering on a coin, such as the lettering on the Presidential dollars. Striking a coin with debris causes an indentation on the coin or the actual debris stamped into the coin. In order to mint any US coin a retaining collar is used to keep the coin in place while it is pressed between the dies.
If the retaining collar breaks dating hammered coins is missing, the coin is struck so that the metal of the planchet is actually expanded outward producing a larger version of the coin with most of the details present. This error is known as a broad struck error. A coin that has been struck out of the collar and has double details such as two partial portraits, one normal and one that is overlapping and extending outside the normal circumference of the coin is denoted as a double striking error.
A brockage results when a coin is stuck in the collar and another planchet enters the collar and is pressed against the coin already minted.
The details of the coins produced have the appearance of mirror images of the obverse and reverse. A die cap is a coin that has been stamped a number of times and has the appearance of a soda cap. Metal flows around the side of the coin and the portrait appears deep in the coin. Variations are not mint errors in the technical sense. Variations in coins are caused by creating hubs and dies that are not exactly the same resulting in dates that can be compared as large to small, wide to thin etc.
These die variations resulted in the large- and small-dated Lincoln centand the large- and small-dated series both in copper and copper-zinc cents minted. Below are photographs of two Brilliant Uncirculated Jefferson nickels.
Note that these are variations of dies used to mint the D Jefferson nickels, dating hammered coins. The die dating hammered coins is clearly evident with the placement of the D in two different locations, one closest to the and the other closest to the rim of the coin. There are some variations created by the mint site using different die sets. The best case of the mint using different die sets is the variation dating hammered coins the letters AM on the Lincoln cent.
The AM letters are either touching or are distinctly apart in some Lincoln cents minted indating hammered coins, and perhaps others to be discovered. Normally, the wide AM design is reserved for the Lincoln proof designs. Below is a photograph of a wide AM Lincoln cent. Unclassified error coins are those that are difficult to categorize. Below are two unclassified error, one with the date flattened in a Jefferson nickel and another Jefferson nickel with a recessed S.
Counter stamped coins have a long history in the early days of minted coins. Many companies used counter stamping as a method to advertise their company. There are thousands of counter stamped coins some of which carry little value while others command values in the thousands.
In any case, these coins were changed after leaving the mint, and are not true error coins. Initials were sometime cut into coins. Some of these coins have been classified as "love tokens" having the initials of the person who counter stamped the coin. Below is a counter stamped Lincoln cent with a dating hammered coins 2 dating hammered coins a bar shape outline, dating hammered coins. This coin was found with some others with personal initials in a 5, piece coin bag purchased from a coin show.

9, votes and 5, comments so far on Reddit I'm a woman and I never cry. My reaction to emotions is similar to guy. When others cry in front of me it makes me extremely uncomfortable. That gets compounded with the idea that because I'm a woman I should be a nurturer and when it's discovered that I'm not it amplifies the awkwardness Ancient Chinese coinage includes some of the earliest known coins. These coins, used as early as the Spring and Autumn period (– BCE), took the form of imitations of the cowrie shells that were used in ceremonial exchanges. The Spring and Autumn period also saw the introduction of the first metal coins; however, they were not initially round, instead being either knife shaped or spade
