I have a great liking for the coins of the Baltic states. By its simplicity, this coin achieves elegance. The fun element of the design is the climbing griffon with sword in the arms. It's probably a rare beastie on coins and even rarer in zoos.
The earliest mention I could find is the arms of the Wenden Voivodeship.
In time, it became the Inflanty Voivodeship, but retained its arms. The armed griffon was kept in its original colour scheme by the Livonian Voivodeship, which evolved to Swedish Livonia and the Duchy of Livonia (the titles Voivode and Duke are roughly equivalent.) The North of that territory became the historical province of Vidzeme. Since the historical province of Latgale also had a griffon (though on a blue field and facing the other way, the griffon was used to symbolise the two provinces in the arms of modern Latvia. Similarly, the lion symbolises Kurzeme and (although its arms figure an elk, not a lion) Zemgale, the other two historical provinces of Latvia.
