Interesting fact

The Denier coin from the Kingdom of Castile and Leon, minted during the reign of John I (1379-1390), was made of Billon, a type of alloy that consists of a mixture of silver and copper. This coin was significant because it was the first time that Billon was used as a material for coinage in the region, and it marked a departure from the traditional use of pure silver in coin production. The use of Billon in coinage was a common practice in medieval Europe, as it allowed for the production of coins with a lower intrinsic value than silver coins, but still maintained a level of durability and resistance to wear and tear.
