The lev is the official currency of Bulgaria. The official currency symbol: лв. The term “lev” meant “lion” in old Bulgarian; the contemporary word for “lion” is luv. The name “stotinka” is derived from the word “sto”, which means “a hundred.” Four lev have been introduced in Bulgaria, the first was adopted in 1881, and the last, in current use, was adopted in 1999. During the adoption of the latter lev, and after a redenomination process, banknotes were introduced in the denominations of 1, 2, 5, 10, 20, and 50 leva, followed by the 100 leva notes in 2003. The 1 and 2 lev notes were eventually phased out of circulation and replaced with coins of comparable value.

The 10,000 Bulgarian leva note front design features the portrait of Dr Petar Beron (1799–1871) was a Bulgarian educator who wrote the first modern Bulgarian primer, named Fish Primer after a dolphin outlined at the end of the book; Beron is recognized as “The father of modern Bulgaria”. The design is completed with a sketch of dolphins and rhinos, and the globe.

The reverse of the note presents illustrations in the academic works of Dr Petar Beron; a telescope, a compass, and a plane of the earth in which the European, Euro-Asian, and African continents are observed. The lettering of the note is presented in the Bulgarian language. This note is part of the 1997 series, and its color is a multicolor underprint.
