US error coins can be identified with many errors happening over the years. It is all about being able to spot an error and identifying which kind it is. The off center errors are those that are resultant when the coin held in the collar are not struck at the right place. This results in an incorrect center with the center device or design missing. When blank coins are being churned out it could result in a chipped planchet. This means that the blank itself is cut improperly. This could result in a chipped coin, a spherical cut, or an elliptical finish. Of course, the coin may have gone into printing and part of the coin that is missing guarantees that the coin when minted is incomplete. The value of the US error coin will be dependent on the shape and what is missing in the coin.

During the minting process when a die is subjected to excessive pressure or it is worn out, the coin is likely to develop a crack. This could be very visible to the naked eye, as the coin would look odd. Apart from this if you ran your finger over the coin, you would realize that it’s got an uneven surface. These cracks and cuds can destroy the portrait on the coin and can be valued depending on the damage it has caused to the coins authenticity. The placement of these natural cuds and cracks is essential in determining value of US error coins. The blank planchets have great value too depending on rim variations.
