The term 'Bulgarian Coin' refers to two different coins used in Bulgaria: the Lev and the Stotinka. The Lev is a three-letter currency symbol that is the official currency of Bulgaria and is divided into 100 stotinki. The Stotinka is an eight-letter currency symbol that is the subunit of the Lev and is equal to one hundredth of a Lev. The Lev was introduced in 1999, replacing the Bulgarian lev, which had been in circulation since 1952. The Stotinka has been in circulation since 1881.
