Karel V, Duits keizer, rekenpenning van het bureau van de keizer 1550

This small silver coin, or rekenpenning, is a 16th-century piece that was used as a counter for calculations in the Imperial Bureau. One side features a profile portrait of Charles V, Holy Roman Emperor, while the other displays the imperial coat of arms. The piece, crafted by an anonymous artist, is a fascinating example of the small objects that played a vital role in the day-to-day workings of the court. This coin, now a part of the Rijksmuseum collection, offers a glimpse into the history of the Holy Roman Empire and its intricate administrative practices.
