A Word About Errors
Doubled Die errors
, like the one above, are produced when a working
die is made from a master die.  The master die sometimes "bounces"
after it initially contacts the working die's
central conical-shaped point.
This momentary bounce may be intentional, as some working dies require
several pressings to create a useable working die.  When the master die
makes its secondary contact with the working die, two or more images
become may become visible on the working die, due to a momentary
rotational mis
alignment about a coin's central point.
All subsequent
planchets struck by this
working die with the doubling error
will have
the same error repeated throughout the die's lifetime,
as much as
100,000 coins.
Die clashes
occur when the dies used to strike the coin blanks (planchets)
come
together without a coin between them.  Elements of either reverse
or obverse side designs transfer to the opposite side of the coins struck
using these damaged dies.  Most of these errors are spotted by automation
or sharp-eyed Mint employees who promptly retire the dies from service.
For this reason, die clashes and large die chips on coins are not found so
often, and are considered to be a rare thing.
Die chips
occur during the course of die usage when small pieces of the dies
disintegrate, shatter or break off the die due to the massive tonnage of pressure
required to strike the planchets and make a clear image.
Double die errors may be the most well-known of errors, but many Collectors
also prize the rare and large die chips and die cracks, as well as the unusually
rare clashed die errors which occur much less frequently.  Many die clash errors
are not as visible, and they are found only after some time of a coin's circulating
lifetime.
Good luck in bidding on this desirable doubled die error from the one
