Dissolution of Czechoslovakia
On 1 January 2009 Slovakia adopted the Euro as its currency with the exchange rate of 30.126 SK/€, and the €2 commemorative coin for 2009, Slovakia's first, featured the 20th anniversary of the Velvet Revolution in remembrance of the common struggle of the Czechoslovak people for democracy. By a quirk of fate, the welcoming speech on the behalf of the European Union on the occasion of Slovakia's entry to the Eurozone was delivered by Mirek Topolánek, the prime minister of the then-EU presiding country, the Czech Republic, naturally in his native language while other guest speakers used English. The Czech Republic continues to use the Czech koruna, or crown.
Biatec
Biatec was the name of a person, presumably a king, who appeared on the Celtic coins minted by the Boii in Bratislava (the capital of Slovakia) in the 1st century BC. The word Biatec (or Biatex) is also used as the name of those coins. In the literature, they are also sometimes referred to as "hexadrachms of the Bratislava type". Biatecs, in fact hexadrachms and tetradrachms made of high quality silver and gold, bear inscriptions in capital Latin letters. Among 14 different inscriptions (for example NONNOS, DEVIL, BUSU, BUSSUMARUS, TITTO), BIATEC appears most frequently. The inscriptions represent the oldest known use of writing in Slovakia and the neighboring territories. The coins have a diameter of 25 millimeters and a weight of 16.5-17 grams. The obverse usually shows various depictions of a head or a pair of heads. The reverse usually shows a horseman, but various mythological and real animals also occur.
