Error coin collecting offers the coin collector an opportunity to learn a more detailed understanding of the manufacturing process, and in turn, refine their knowledge and hone their skills in recognizing the finer details of their existing collections and broaden their interests.
By identifying errors in planchet fabrication, striking mishaps, and die failure, the basic knowledge of the minting process gives way to a more sophisticated, complete understanding.
Acquiring and studying the numerous varieties, however, can be an expensive, timely, and often exclusive undertaking. And while everyone should be encouraged to take the opportunity to do so, for the joy and knowledge numismatics provides, we would also like to increase the education and enjoyment to a broader audience.
In the forthcoming issues, Intaglio Mint will offer a comprehensive collector set of error coins fabricated using the very techniques that lead to accidental error coins. Varieties will be released in various Types (Planchet, Striking, and Die) and Classes within those Types in order of complexity of fabrication. For example, common errors such as clips and off center will be released prior to multi planchet errors such as brockages with final production runs of die failure errors, cuds and die clashes, being last. Pricing is tied to the level of complexity involved in the error creation. Albeit controlled, these are not standard minting practices and require an expert knowledge of minting processes in order to maintain safety and quality standards.
Series 1 – Off-Center
The term off-center describes a coin or medal that has been stamped off center with the dies. This is usually the result of the planchet being misfed into the coining chamber. The resulting coin or medal has a design that is only partially visible, and the remaining portion being unstruck planchet.
There are interesting variations in the cause of modern off-center strikes, stemming from the position of the coining collar. If the position of the collar remains down, the resulting strike will often be flat and free of imprint or distortion from the collar. In this regard, these are closely related to and often confused with a broad strike. If the coining collar remains up, the resulting strike often becomes bent and imprints of the collar can be diagnosed.
Due to the varying degrees which a coin or medal can be off center struck, the range in difficulty of diagnosing an off-center can vary. However the harder it is to determine off center signifies that the error has very little collector interest. The more off center, the easier it is to identify, and the more dramatic the error, the more collector interest in the piece.
