10 levs, 1999

The obverse side carries an engraving of Doctor Peter Beron. To the right of him appear the frontispiece and plates from his 1824 “Primer Containing Diverse Instructions”. Colloquially known as Riben Bukvar (the Fish Primer), this was infused with the ideas of advanced European education.

Doctor Peter Beron (1799 - 1871), a National Revival scientist, Renaissance Man, reformer and sponsor of Bulgarian learning, this linguist with nine languages authored the first secular instruction book in Bulgarian, and encoded modern Bulgarian grammar. He contributed greatly to the modernisation of education and establishment of contemporary Bulgarian culture.

The reverse side shows sketches taken from Peter Beron's treatises in astronomy, and his personal telescope.
