4. Preservation of Value and Care

4.2 What Causes a Collector Coin to Lose Value?

Explanation of the Question 

When purchasing modern coins and medals, collectors often place particular importance on a condition that is as original and well-preserved as possible. As collecting experience increases, the question often arises as to which influences can change the condition of a collectible and how this can affect its collector value. Many collectors are also interested in the role that supply and demand play in the subsequent development of value and which factors they themselves can influence through proper handling.

 

Answer

The collector value of a modern collector coin or collector medal is influenced by various factors. The condition is of particular importance. A deterioration in condition can generally reduce the collector value. Common causes include mechanical damage, chemical changes to the surface, improper cleaning, unsuitable storage conditions, as well as the loss of originality or completeness of a collectible.

Regardless of the condition, the achievable market value is additionally influenced by supply and demand. Careful handling can help preserve the original condition over the long term, but cannot guarantee a particular development in value.

Explanation

Condition is one of the most important criteria when assessing modern collector coins and collector medals. Even minor changes to the surface can permanently impair the original condition.

Common causes include mechanical damage such as scratches, pressure marks, abrasion, or damage caused by dropping. Such changes generally cannot be reversed and can permanently reduce collector value. High-quality minting qualities such as Polierte Platte (Proof) are particularly sensitive, as even the smallest changes to the surface can become visible. Satin-finished and other high-quality surfaces can also be sensitive to mechanical impact.

Chemical changes to the surface can likewise impair collector value. Fingerprints, unsuitable storage conditions, or environmental influences such as humidity and sunlight can promote tarnishing or other chemical reactions. Depending on the precious metal, alloy, or surface treatment, collectibles can react with varying degrees of sensitivity.

A frequently underestimated cause of loss in value is improper cleaning. Even wiping with a soft cloth or using unsuitable cleaning agents can permanently alter the original surface or cause fine micro-scratches.

For many collectors, the originality of a collectible is also of great importance. Subsequent alterations to the surface or other interventions can permanently change the original condition and thereby reduce collector value.

The completeness of a collectible is also often an important factor. For many modern collector coins and collector medals, for example, the original capsule, original storage system, presentation case, or certificate of authenticity may form part of the overall concept. Damaged or missing components can – if they were originally included in the delivery – impair the collector value.

In addition to condition, the achievable market value is also determined by supply and demand. Interest in particular designs, series, or issues can change over time. Therefore, the future development in value of a collectible cannot generally be predicted.

The condition is one of the most important factors influencing the collector value of a modern collector coin or collector medal.

Mechanical damage, chemical changes to the surface, improper cleaning, or missing original components can permanently impair the original condition and therefore often reduce collector value. However, supply and demand always also determine the actual achievable market value.

Handle high-quality collector coins and collector medals preferably only with suitable gloves or directly by the edges, and avoid any unnecessary contact with the surface. Whenever possible, keep your collectibles permanently in their original capsule or original storage system and store them in a dry place protected from strong sunlight.

Before attempting to remove dirt or fingerprints by polishing or cleaning, bear in mind that improper cleaning can cause a greater loss in value than the original contamination itself. An original and unchanged condition is of decisive importance to many collectors. When in doubt, it is therefore advisable to seek professional advice before undertaking any cleaning or treatment.
