We offer you the colored commemorative coin dedicated to one of Bulgaria's legendary opera singers Boris Christov. You can see him as the character of Boris Godunov from Musogorski's opera named after the character himself.

This is the first three-component commemorative coin, by means of which BNB launches its new series: "Distinguished Bulgarian Voices." Each of the three components is in a different colour. The coin is made entirely out of silver but one of its rings has been oxidized to black while another has been treated with gold.
