What does Kuna mean Croatian?

Excuse me, could you please clarify the meaning of the word "Kuna" in Croatian? I understand that it has some significance in the country's financial system, but I'm curious about its etymology and cultural connotations. Is it a term that has historical roots, or is it a more recent addition to the language? Additionally, how does the Kuna play a role in the daily lives of Croatians, and what impact does it have on the country's economy? Thank you for your time and consideration.
