The Bulgarian National Bank issued a revised 50-lev into circulation on November 1. It is part of the new series which began with the 100-lev note that was issued last year. The new 50-lev note has more sophisticated security features.
The note is brown and tinted which is varnished after printing. The note has the image of Pencho Slaveykov along with the buildings of the National Theater and National Library. The new features include a tactile feature for the visually impaired in the form of four thick lines and seven thin lines.
