Galvanisierungs

Galvanisierungs in European Charlemagne coinage refers to the process of applying a protective zinc coating, also known as galvanization, to the surface of metal. This was a novel method used extensively in the coinage systems of Europe, particularly during the reign of Charlemagne. The technique involved dipping the metal in a zinc-rich bath, resulting in a corrosion-resistant layer.

Initially, metal coinage in Europe was minted from bronze or brass, but the introduction of Charlemagne's system brought about significant changes. The new coins featured a base of copper or bronze, protected with a layer of galvanized zinc, which provided enhanced durability. This innovation significantly improved the resistance of coins to corrosion and wear, ultimately leading to the widespread adoption of the galvanisieruns method in European minting.

The introduction of galvanisierunds resulted in several benefits, including increased coin circulation and reduced losses due to corrosion. However, some numismatists have noted that the denser zinc coating on Charlemagne's coins may also have facilitated induced wear, where debris and grime accumulate on the applied zinc layer, causing uneven wear on the coin's surface. Today, Galvanisierungs is not commonly used in coin production, but the development signifies an important milestone in the evolution of minting techniques and the push for more durable coins in the early medieval period.
