Mint-made Errors
Mint-made errors occur when coins are made incorrectly at the mint (facility), mint, including anything that happens to the coin up until the completion of the minting process. Mint error coins can be the result of deterioration of the minting equipment, accidents or malfunctions during the minting process, or interventions by mint personnel. Coins are inspected during production and errors are typically caught. However, some are inadvertently released into circulation. Modern production methods eliminate many errors and automated counters are effective at removing error coins. Damage occurring later (post-mint damage) may sometime resemble true mint errors. Error coins may be of value to coin collecting, collectors depending on the rarity and condition. Some coin collectors specialize in error coins. 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 h ...

It was the first standard silver dollar minted since the passage of the Coinage Act of 1873, which ended the free coining of silver and the production of the previous design, the Seated Liberty dollar. It contained 412.5 Troy grains of 90% pure silver (or of pure silver). The coin is named after its designer, United States Mint Assistant Engraver George T. Morgan. The obverse depicts a profile portrait representing Liberty, modeled by Anna Willess Williams, while the reverse depicts an eagle with wings outstretched.

Die (manufacturing)
A die is a specialized machine tool used in manufacturing industries to cut and/or Forming (metalworking), form material to a desired shape or profile. ''Stamping (metalworking), Stamping dies'' are used with a machine press, press, as opposed to ''Draw plate, drawing dies'' (used in the manufacture of wire) and ''Die casting, casting dies'' (used in Molding (process), molding) which are not. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology. Continuous production, Continuous-feed laser cutting may displace the analogous die-based process in the automotive industry, among others. Die stamping Blanking and piercing are two Shearing (manufacturing), die cutting operations, and Bending (metalworking), bending is an example of a die forming operation. Die forming Forming operations work by deforming materials like sheet metal or plastic using force (Compre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Die Crack
A die defect is a unique and unintentional flaw in a coin die and is created through excessive use or polishing of the die. A die bearing such a defect is occasionally referred to as a defective die. Generally, and depending upon the magnitude of the defect, coins that are produced from these dies are considered error coins. Also, the term encompasses a wide variety of design errors that were engraved into the die originally and were slipped into circulation before the incorrect design was discovered. Types Die crack A die crack occurs when a die, after being subjected to immense pressure during the minting process, cracks, causing a small gap in the die. If this damaged die continues to produce coins, the metal will fill into the crack, thus revealing a raised line of metal in the finished coin. Specimens with more prominent die cracks can command a high premium and are valued greatly by some collectors. However, less obvious errors are quite common, especially in the 50 States ...

Die Deterioration Doubling
{{numismatics Die deterioration doubling (DDD) is a common form of mint-made error on many United States and Canadian coins that results from degradation of the die used to strike the coin. Due to a combination of improper preparation and treatment of the dies, excessive wear, and overuse, die deterioration doubling has occurred on nearly every series issued by the US mint in recent times. Certain coins are more susceptible to it than others, due to various factors, but it does occur on most series of coins. Causes Annealing Errors During the annealing process of die making, two main errors can occur, resulting in less than perfect dies. It is impossible to tell without expensive and lengthy tests whether these errors occurred, but they will lead to significantly weaker dies and a higher tendency to deteriorate quickly. The first thing which can happen to a die in this process what metallurgists call decarburization. Decarburization is the result of an improper mix of metal ...
