An error coin is a mistake made by the mint during the process of its production. This affects the appearance of the coin in different ways. Before you return an error coin, you must think about its value, because some are worth hundreds or even thousands of dollars. Add these to your coin collection to boost its value.

Capped Die Strike

When a die cap error occurs, the dies continue to strike more coins despite a coin capping around one of the dies. The coin stuck with that certain die will look blank or has differing degrees of mushiness due to the obstruction of the obverse die.

Indent

This error coin occurs when a blank planchet partly overlaps another in the striking chamber and is struck the overlapped area on the struck coin will display a blank and indented section.

Double Dies

This error coin is one of the most famous type; this refers to the doubling of a part or all of the image on a coin. The doubling occurs on one part of a coin and normally shows in the lettering of a coin. In some cases, parts of the design of the image can also have doubling effects, if it is noticeable enough. The 1955 doubled-die Lincoln penny is one of the most well-known double die coins. The coin values of these are approximately $1,000 in well-worn condition.

Brockage

This coin error occurs in the same way as an indent, except that a struck coin is pounded onto a blank planchet, this results in a mirror-like image impression that looks distorted because of metal flow.

Struck through Error

This coin error occurs when a foreign object lies on top of a planchet and makes an impression of itself on a struck coin. Various objects such as string, grease, plastic, staples, bandaid and others have made impressions on coins.

Double Denomination

This error takes place when a pair of dies that have a different denomination strikes an already struck coin. Such coins will display details of both denominations. The design of the last dies to strike onto a coin is most likely to appear. Some these coins barely display the detail of the denomination of the first strike.

These errors have varying coin values, get an appraiser to help you determine their worth and if you can add them to your collection to boost its value. Other coin mistakes are out there, when you see a different looking coin, keep it and have an expert evaluate it. You might have something worth hundreds or even thousands of dollars.
