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.
Die wear - The loss of detail on a coin due to wear on the die used to strike it.
Dime - The denomination, ten cents, issued since 1796 by the United States.
Ding - Slang for a small to medium sized mark on a coin.
Die Wear
Dies are commonly used to strike huge numbers of coins. Even if they are replaced before they break, gradual wearing can lead to the production of coins which appear to be weakly struck.
Die Wear - Dies that get worn through use will start to strike coins with less definition and the coins that are weakly struck due to die wear will often sell for lower than better struck coins.

Deterioration in a die caused by excessive use, resulting in coins of less detail than desired.

Die Wear - Dies as they strike a vast number of coins start to show signs of wear; this causes the coins they strike to appear rather weakly struck. Coins can be as struck but appear to be only Very Fine.
Die Wear - After striking coins repeatedly, due to heat and friction, the surfaces of the dies show wear. Periodically, the striking process is halted and one or more of the dies are resurfaced to remove blemishes.

The two photos below are the same coin, a 1868 business strike, and are examples of die erosion.
Due to Die Wear
This is also discussed briefly under grading, but it needs to be dealt with here in a little more detail.
Finally, die wear on the reverse is evident with the AQE ethnic and the owl's feet. Despite the popularity of Mass Owls, their dating and attribution is one of the great underexplored areas of ancient numismatic scholarship.
High pressure (of the dies) when striking the coin along with die wear (really the lack of wear on the die) are necessary for the appearance of full bell lines on a newly struck coin.
Die deterioration doubling is the result of die wear or premature die erosion due to a variety of possible causes including improper heat treat, etc.
During the production process, technicians at the Mint endeavored to space the dies closely enough together that the coins would strike up properly, but wide enough apart that excessive die wear and breakage would not occur.
This is not due to die wear, but rather design opposition caused by the eagle's head being directly opposite the shoulder of Liberty on the obverse. Adjustment marks are also common on these early silver coins.
The alloy was very hard and caused rapid die wear. The result was weekly struck coins. In 1863 the Mint observed that citizens readily used private tokens made of a softer bronze alloy (95% copper and 5% tin and zinc).
Differences in these coins can be attributed to die wear, striking diferences and coin wear. Note the faint outline of the bust (upside down) and the strong 'DO' incuse at the lower left of the reverse.
This applies to planchet laminations, lint marks, die rust, die wear, or practically any other mint caused defect. (Note: Minor die scratches and clashed dies are not usually considered to be serious defects, and hardly affect the grade, if at all.
First Strike: A coin struck early in the life of a die before die wear occurs. This usually is considered desirable since these coins are likely to have good solid strikes and excellent detail.
Flip: A clear plastic coin holder.
the results of progressive die wear, mintage figures and even the socio-political context of coin mintings are also matters of interest. In sum, there is very little about money that is not a valid numismatic field of study.
The reasons for poorly struck coins usually fall back to striking pressure and die wear. If striking pressure is too low then the coin will not be fully struck up.
Fully struck with outstanding surfaces. This is a great example for this one-year type. There is an area of extreme die wear on the reverse at 4:00. This is an interesting die artifact and adds a bit of "WOW" to the coin.
Rays Nickel The first five-cent pieces, issued in 1866 and 1867, had rays interspersed between the 13 stars on the reverse. Early die wear and breakage led the mint to delete these rays on the remaining coins of 1867-1883.

Like all 1839 "Head of 1838" eagles, this coin bears an overdate and uses the same die as the 1838 eagles, merely modified at the date. Slight overpunching is still visible at the right edge of the 9, though lapping and die wear have effaced most ...

Die wear led the mint to delete these rays on the remaining coins of 1867-1883. Red Book The Guide Book of United States Coins, issued each year since 1947, has a bright red cover and an ever-increasing cover price.
