The Convertible Mark

I found a 20 convertible mark note on the table earlier today and thought of how the currency of Bosnia and Herzegovina has a German name and how you can't exchange the currency or buy the currency outside of BiH.

Some fun facts:

The convertible mark was established by the 1995 Dayton Agreement.

It replaced the Bosnia and Herzegovina dinar, Croatian kuna and Republika Srpska dinar as the single currency of Bosnia and Herzegovina in 1998. 

Mark refers to the German mark, the currency to which it was pegged at par.

The name derives from the German language.

The three official languages in Bosnia and Herzegovina (Bosnian, Serbian and Croatian) have adopted German nouns die Mark and der Pfennig as loanwords marka and pfenig. 

Banknotes and coins of Bosnia and Herzegovina have many mistakes and inconsistencies (maybe more than any other currency).
