Denier - John I Segovia ND

The Denier coin of John I (Segovia) from the Kingdom of Castile and Leon (Spanish States) is interesting because it was issued during a time of great change in Europe, particularly in the realm of coinage. The use of billon, a mixture of silver and copper, was a common practice during this period, as it allowed for the production of coins that were more durable than those made of pure silver. However, the use of billon also led to issues with counterfeiting, as it was easier to debase the coin by adding more copper and less silver. This coin, therefore, represents a fascinating intersection of economic, technological, and political factors during the late medieval period.
