Carolus III Dei Gratia 1778 coin

The coin appears to be from the year 1738, as indicated by the numbers inscribed on it. Around the edge, there are various inscriptions, though they are somewhat faded and difficult to read clearly. In the center, there seems to be the faint outline of a profile, possibly a historical figure, but the details are mostly eroded, making it challenging to identify any specific features. Despite its age and wear, the coin has a distinct historical charm, with its metallic sheen reflecting light subtly.
