AWESOME BLANK PLANCHET ERROR! -Coin Roll Hunting-
A planchet is distinguished from a simple coin blank by having a raised rim. This rim is applied to the blank by an upsetting mill, which compresses the blank's edge as it is spun between two beveled surfaces. Planchet errors encompass all mistakes resulting from a defective blank, whether or not it has passed through the upsetting mill.
One error that can occur is for the planchet to be counted and bagged without going through the press at all. The result is a blank planchet, which may or may not be milled. Mint-error collectors look for blank planchets when sorting through a bag of coins, since there is little chance that a blank planchet will be wrapped in a roll or reach circulation undetected.Xda herolte
The most basic type of planchet error is when the wrong planchet is fed into a press. Since both the loading tube and the die collar are sized for the appropriate denomination of coin, only planchets of the correct or smaller size can be struck within the press.
This means that a dime planchet can be struck by quarter dollar dies, but a quarter dollar planchet cannot be struck by dime dies, since it won't fit into either the feeder tube or the collar. Another planchet error, one that is highly sought by collectors, occurs when a planchet intended for a foreign nation's coinage is struck by dies for a United States coin.
This type of error was more common beforewhen the U. Mint cut back its production of coins for other countries.
It still may occur, however, as planchets are supplied to our mints by commercial vendors, and these vendors also service the mints of other countries. It's not impossible for a shipment of planchets intended for one country to accidentally include those of another. Finally, there are more subtle errors to be considered. An error coin can have the right diameter and the proper metallic composition but the wrong weight and thickness.
This might happen, for instance, if metal strip for dimes was run through a blanking press set up to produce statehood quarter planchets. Both coins have the same color and composition, but thinner strip is used for dimes.
It should be noted that off-metal coins are scarce, but also illegal to own. Because they do not conform to specifications, they are considered counterfeit and the government will confiscate them.Diagram based ford festiva workshop wiring diagram
Perhaps the most popular die errors are major die breaks, commonly known as 'cuds.There are three categories of error coins as provided by the American Numismatic Association.
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 controversy over what constitutes a true mint error. 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. 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. 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 may be in a state that causes peeling on the surface of the coin. 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 of preparing a set of new dies improperly from the original hub results in coin errors such as doubling, 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, or polishing lines.
Dies that are damaged and used in the minting process also create errors resulting in coins having die chips embedded in the surface of the coin. 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 rotated.Gmail draft

In ancient times, the flan was heated before striking because the metal that the coin dies were made of was not as hard as dies today, and the dies would have worn faster and broken sooner had the flan not been heated to a high temperature to soften it.I fontanelli restano “a secco”. in compenso la
Today's dies are made from hardened steeland the presses use many thousands of pounds of force to strike coins varying according to the size of the coin and the complexity and relief of the design. In addition, today's coins have much lower relief than ancient coins.
Because of this, the planchet no longer needs to be heated immediately before striking, although it is annealed by heating and slow cooling which softens the coin. Preparation of the modern planchet involves several steps. First, the metal or metals in the case of clad or multilayered coins is rolled out into a large roll or sheet of the correct thickness. This process is often done by third parties, not by the mint itself.
These flat rolls or sheets of metal are then punched out into round blanks that are a little larger than the coin being struck. The blanks are then subjected to an annealing process that softens the metal through heating to approximately degrees Celsius degrees Fahrenheit and are then slowly air cooled.
They are then washed to remove residue from the annealing process and dried. The blanks then go through an upsetting mill that raises the rim on the edge of the coin. Finally, the planchet is struck. After striking, it becomes a coin and is no longer a planchet. Occasionally, a planchet will escape the mint without having been struck. This is a blank planchet error, and is usually worth a few dollars for modern coins. Occasionally, blank planchets can be rare and valuable, such is the case for Morgan Dollar blank planchets, although authentication and appraisal by a coin grading service is highly recommended for such pieces as they would be fairly easy to counterfeit.Phoenix mining

So definition time. A planchet is a round metal disk that is all set up and good to go to be struck as a coin older terms are flan or blanks. It is the last step of the material before it is struck into a coin.
Backing up a bit, for the US Mint but is pretty standard across the boardhow a coin is made, in very very simple terms and here is a lovely video of the process. The planchet blank is not struck, but still makes it through all seven stages.
These errors may or may not have rims, with the rimless ones having a bit more value, as they made it through one more step without getting pulled.
Errors: Planchet Errors
Far left has a rim, right does not. Anyhoo … This is caused when in the blanking press one of a few things happen. The value of these coins depend on the size and location of the clip. The sheets that we talked about earlier, 13 inches wide and 1, feet longwell they are created by rolling out metal into the sheets. Sometimes mistakes are made, and the resulting sheets may be too thick or thin. As US coins are supposed to weigh a certain amount, and the variation within any mintage is quite narrow, if the planchets are incorrect, this is an error.
If a sheet has been rolled with an indentation on it, it will also throw off the correct weight. Just as the previous section dealt with the sheeting being rolled out, lamination errors occur at the sheet level.
Discoloration, splitting, uneven surfaces, and yes, peeling, are the result of the error inside the planchet. This is the most interesting of the planchet error, at least, to me. This is where the planchet for one domination is stuck with the die from another. To put it a bit easier, a penny strike on a nickel planchet, or dollar on dime planchets. Another wrong planchet error that is due to human error is when the mint changes the make-up of the coins.
They adjust the alloy composition of the planchet. Some of the older planchets are fed into the coin press with the new dies.
This is also quite rare, with the most obvious example being a copper cent or a steel cent. The last kind of wrong planchet error is an older error, and incredibly atypical. In the 17 th th centuries, sometimes a planchet from a foreign country was put into a US coin press. Modern US coins are made from layers of different metals. Most have an inner core of copper, and outer layers of a nickel-copper alloy that is silver colored.
Think dime, quarter, half dollar. Anyhoo, if the process did not work correctly, the layers can fold, peel, or in some cases completely separate. Up next will be striking errors …. Schofield Deirdre G. Byers Ailie F. Planchet errors Posted on April 5, Benefit Auction Division.Sometimes planchets for one coin denomination are fed into a coin-stamping press equipped with dies of another denomination.
This results in a coin that has been stamped with a design intended for a differently sized coin. The resulting errors are prized by collectors, though they are usually caught during the manufacturing process and destroyed. Some examples include cents struck on dime planchets, nickels on cent planchets, or quarters on dime planchets.
This type of error should not be confused with the much rarer mule which is a coin struck between dies that were never intended to be used together such as a coin with nickel obverse and a dime reverse. Wrong planchet errors may also occur when the composition of the coin changes. Such situations generally arise when the mint has decided to change the alloy or plating of the coin in the new coinage year, but a few planchets from the previous year—and thus of the previous composition—have yet to be struck.
Such coins are rare and often highly valued by collectors, as with the copper cents and steel cents. A much rarer error is a denomination struck on a foreign planchet. This did occur occasionally with United States and before that American colonial coinage in the 17th, 18th, and 19th centuries, and then very rarely in the 20th century. Wrong planchet and off-metal errors occur when a correctly made blank from one denomination is accidentaly fed into a press for another denomination.
Examples are a nickel struck on a cent planchet and a cent struck on a dime planchet. The coin struck on an incorrect blank will weigh exactly what the denomination of that blank would have been.
An even more dramatic wrong planchet error is a coin struck on a previously struck coin of a different metal. Multi Struck Coins. Partial Collar Coins.Eu4 province warscore cost

Wrong Planchet? How can one determine whether or not a coin is struck in the wrong metal? Any opinions? Tired-of-CardsFeb 21, Log in or Sign up to hide this ad.
I cleaned out my fish tank and in doing so found that my children had put coins in the tank. This is exactly what they looked like. The best way to figure out if a coin is struck on the wrong planchet is to weigh it on a good scale.
If it was a nickel struck on an penny planchet, it would be thinner than what we see in the 3rd photo, and it would weigh half as much as a normal nickel 2. If for whatever strange reason a copper planchet with the exact dimensions of a nickel planchet made it into the mint, it would have a slightly different weight than a normal nickel.
BlaubartFeb 21, Anything is possible, but like some of the other guys have posted the best way to determine is by weight and dimension. The best advice I can give is to let a coin dealer examine and give thier opinion. I have seen nickels struck on a cent planchet, and they do not look like that.
Hunt1Feb 21, ConderFeb 21, I have a copper nickel and it looks like its errored around the edge and in other places can anyone tell me what it may b worth I can shoe picture. CouriousTrishAug 8, Welcome to CoinTalk! Pictures please! SilverDollarAug 8,
