Mint-made errors are errors in a coin made by the mint during coin error forum the minting process. Groups of coins with distinctive characteristics are known as varieties.

term error refers only to coins with unintended differences. Nevertheless, not all errors are varieties. Although there may be many identical examples of a some errors, others are unique. For example, there may be many indistinguishable examples of coins with a specific die crack, while off-center strikes tend to be unique. Being unique does

not mean that an error is valuable. Although no other coin may be identical to a coin with an off-center strike, off-center strikes happen often enough that buyers can choose from many examples each of which varies slightly from the other. Mint error coins can be the result of deterioration of the minting equipment, accidents or malfunctions during the minting process, or intentional interventions by mint personnel.[1] Accidental error coins are perhaps the most numerous and in modern minting are usually very rare, making them valuable to numismatists. Intentional intervention by mint personnel does not necessarily include a deliberate attempt to create an error, but usually involves an action intended to improve quality that miscarries and creates error coins instead. Errors can be the result of defective planchets, defective dies or the result of mistakes made during striking. The planchet, die, and striking (or PDS) classification system happens to correspond with the mintmarks of the three largest U. S. mints, Philade
and even human error. While most coin errors are found by employees of the mint and melted down to be used again in future coins, some of them are accidentally released to the public and do find their way into circulation. There have even been a coin error book few cases throughout history when the error coins were deliberately made and released (probably sold) by unscrupulous or

money hungry mint employees. It is believed that this was the case when an error coin showed up in 2000 with the front of a 50 coin encyclopedia State Quarter and the back of a Sacagawea dollar. With lots of publicity from the media throughout the country, people began to go through their coins hoping to find one in their pocket or purse. And so it happened that there was a surge https://en.wikipedia.org/wiki/Mint-made_errors of new people joining the hobby of coin collecting. And hey, how many other products can you find where a booboo or mistake can make the item more valuable than the perfect ones. If it were any other item, we would return it to the store for a refund. Here are a few examples of some types of error coins: Off-center Struck Coins:This is a pretty common type of coin error and occurs when a coin blankA Blank is a prepared disk of metal with a slight http://www.coin-collecting-guide-for-beginners.com/error-coins.html rim on the edge on which the coin design will be stamped. doesn't go into the coining machine right. If part of the blank is out of position when the die comes down, the part that is sticking out will not be stamped with any of the design. Click Image to Enlarge Double- and Multiple-Struck Coins:This coin error can occur when a coin gets stuck in the coin press and gets stamped more than once. Sometimes it can get stamped over and over again. It is fairly common to find Double Struck Coins, or coins that have been struck twice, however, finding a coin that has been struck more than twice, or a multiple struck coin, is rare. Click Image to Enlarge Brockages: This is another error that occurs when a coin gets stuck in the coin press. When a blank then enters the die, the two coins are struck together and the blank receives a mirror image on one side of the coin that is still in the press. The original coin in the die gets a messed up front and the new blank that entered the die is the brockage. Click Image to Enlarge Wrong Metal/Wrong Planchet Errors:Just as the title suggests, these error coins have been struck on a planchet made of a metal that was not intended for that particular coin, or maybe not that particular year the coin was made. I will use the 1943 cent as an example. These coins were made of zinc coated steel instead of the usual 95% copper and 5% ti
of Sale O Checkout Mint Error Definitions Clipped Planchet: Curved Clip A curved clip occurs when the sheet of planchet strip is not advanced forwards far enough after having blanks punched out, causing the blanking dies to overlap https://sullivannumismatics.com/mint-error-definitions the previously punched out holes. This results in coins with curved areas https://sullivannumismatics.com/blog/certified-mint-error-coins-what-know of metal missing called a curved clip. Clipped Planchet: Disc Clip This clip is defined as being a clip so small, it can only be seen on the rim or in the "shift" of metal on the edge, but which does not effect the coin's diameter in any coin error way. So for example, youl might see a small dimple of metal missing on the rim, but the coin would still be perfectly "round." On a clad coin , you will see a visible "shift" in the layers of metal on the edge where the disc clip is, but the coin will still be completely round. Clipped Planchet: Straight Clip coin error definitions A straight clip occurs when the blanking dies punch planchets out of the planchet strip in such a way that they overlap one of the edges of the planchet strip. The punched out planchet will have a straight edged clip, call a straight clip. Clipped Planchet: Outside Corner Clip If the blanking dies overlap one of the corners of the planchet strip, the result will be an outside corner clip. The coin will have a right angled clip. A very rare error type. Clipped Planchet: Elliptical Clip An elliptical clip is a coin which is struck on a oval or elliptically clipped planchet. The error is a close relation to the incomplete clip, but is different in that when it punches the previously partially punched planchets, it punches them out all the way resulting in an overlap that produces an elliptically shapped planchet. Clipped Planchet: Incomplete Clip This error occurs when the blanking press does not punch all the way through the planchet strip, and then retracts. Then the planchet strip is not advanced forward all the

Sullivan on 06/02/2015 - 08:45 Certified Mint Error Coins: What to Know Third party grading services are extremely popular with today’s collector. The grade, authenticity, and any “problems” on a coin are noted on the holder. In theory, most of the work is done, and all the collector has to worry about are the simply things, such as the basic eye appeal of the coin, if they want to own the coin, and if they can afford the coin. Most collectors nowadays supposedly do not need to learn much about grading, authenticity, or finding out about the potential “problems” on coins, since slabbing has presumably eliminated those worries. The reality is different. Coins do indeed get slabbed by grading services with problems, the grade is hit and miss since coin’s are often “upgraded”, and counterfeit coins are found from time to time in holders. Admittedly, grading services have done a good job of reducing these problems, but they have not and never will eliminate them, which means coin collectors have to learn these skills for themselves if they want to build a high quality collection. When slabbing coins moved into the error coin field some 15 or so years ago, collectors embraced slabbed errors. The same benefits of grade, authenticity, and making sure the coin is problem-free all applied to errors, but additionally the error coin was described on the holder by an expert, leaving error collectors without the need to attribute their errors as to what error type they where. As with normal coins, the reality is that collectors do indeed need to learn about the coins, and not simply plunk the money down because the grading service holder says the coin is a particular grade and error type. Let’s look at the primary considerations for error collectors, and how to address potential problems. Grade All the services grade errors a little bit differently. The more “normal” a coin is (in other words, the more the coin’s surfaces are error-free) the more accurate the error coin’s grade will be. If you have a coin with a full brockage obverse, it is much harder to gra
