The main metal used to make coins is polished brass alloyed with other metals. With the use of different oxidizing and polishing processes we get the different finishes or colors of the coins.
The manufacturing process explained in the following images. From a photograph we elaborate the designs of the coins, the artisans capture that design in a punch or die that we use to mint the coins or medals.
The coin comes in a plastic protector (as seen on the photos).
Size: 30mm diameter and 2mm thickness
Please note: Banco de España has also issued a coin for the holy year (only available in banks). This is not that coin.
