What is a faulty gold coin ?

The coins are drawn automatically, according to a predefined model. It happens that certain striking elements go wrong, or that a technical problem arises. Certain imperfections appear, more or less blatantly. These defects then contribute to the rarity of the piece, and increase the value of the object.

These faulty coins are prized by collectors, because they demonstrate an error, or past know-how. However, this singularity does not change the face value of the coin, but only its premium.

The main errors observed on faulty parts are due to:

• Assemblies;
• To the settings;
• To the machines.

The faulty marks are found on the blank, the corners and the ferrule. The most common faults are:

• Off-center marking;
• A rough tackle;
• Poorly struck hallmarks;
• A surplus on the list;
• Broken corners;

The faulty part results from a machine error or inattention. It is not intended, and does not affect the value of the piece. The fault is independent of all will. Conversely, counterfeit coins are the product of counterfeiters, who wish to fool people. The appearance is altered in order to deceive and take advantage of printing errors.

To differentiate faulty parts from fake parts, you must contact a professional. Using a magnifying glass, an electronic scale or even a magnet, the expert carries out various checks. Indeed, there are several ways to deceive and create fake coins. Acid deteriorates the patina and the inscriptions, it is possible to shrink it, or even to artificially create marks.  

Officially, the faulty coins have no other values ​​than those written on the reverse. However, collectors exchange the faulty pieces according to supply and demand. Thus, a gold Louis or a Napoleon Franc can be exchanged for several thousand euros, or even hundreds of thousands of euros, in the United States.

You can acquire counterfeit coins from numismatists, but also at specialized auctions. They are organized regularly in France, but also in Luxembourg, Italy and Belgium.
