die An engraved stamp used for impressing a design (images, value and mottoes) upon a blank piece of metal to make a coin. One die is used for each side of a coin. Nicholas 2011-05-30
die alignment Term to indicate the relative position of the obverse and reverse dies. When the dies are out of alignment, several things can happen: If the dies are out of parallel, weakness may be noted in a quadrant of the coin's obverse and the corresponding part of the reverse; and if the dies are spaced improperly, the resultant coins may have overall weakness; if the dies are spaced too close together, the resultant coin may be well struck but the dies wear more quickly.

die break An area of a coin that is the result of a broken die. This may be triangular or other geometric shape. Dies are made of steel and they crack from use and then, if not removed from service, eventually break. When the die totally breaks apart, the resultant break will result in a full, or retained, cud depending whether the broken piece falls from the die or not. EgCollector 2011-06-10
die crack A raised, irregular line on a coin, ranging from very fine to very large, some quite irregular. These result when a hairline break occurs in a die. EgCollector 2011-06-10
die line These are the raised lines on the coins that result from the polish lines on the die, which are incuse, resulting in the raised lines on the coins. EgCollector 2011-06-10
die rust Rust that has accumulated on a die that was not stored properly. Often such rust was polished away, so that only the deeply recessed parts of the die still exhibited it. A few examples are known of coins that were struck with extremely rusted dies - the 1876-CC dime, for one. EgCollector 2011-06-10
die stage There are two definitions for this term. One, many numismatists use it as a synonym for "die state." Two, some numismatists use the term "die stage" to refer to the specific status of a certain die state. For instance, in die state XYZ this coin exhibits a large cud at six o'clock, but in this particular die stage the cud isn't fully formed. EgCollector 2011-06-10
die state A readily identified point in the life of a coinage die. Often dies clash and are polished, crack, break, etc., resulting in different stages of the die. These are called die states. Some coins have barely distinguishable die states, while others go through multiple distinctive ones. EgCollector 2011-06-10
die striations Raised lines on coins that were struck with polished dies. As more coins are struck with such dies, the striations become fainter until most disappear. EgCollector 2011-06-10
die trial A test striking of a particular die in a different metal. EgCollector 2011-06-10
die variety A coin that can be linked to a given set of dies because of characteristics possessed by those dies and mparted to the coin at the time it was struck. In the early years of U.S. coinage history, when dies were made by hand engraving or punching, each die was slightly different. The coins from these unique dies are die varieties and are collected in every denomination. By the 1840's, when dies were made by hubbing and therefore were more uniform, die varieties resulted mainly from variances in th EgCollector 2011-06-10
die wear Deterioration in a die caused by excessive use. This may evidence itself on coins produced with that die in a few indistinct letters or numerals or, in extreme cases, a loss of detail throughout the entire coin. Some coins, especially certain nickel issues, have a fuzzy, indistinct appearance even on Uncirculated examples. EgCollector 2011-06-10
