This is an uncirculated 2010 Greenland 10 Kroner brass fantasy pattern coin, designed and produced by numismatist Joseph E. Lang to celebrate the native Arctic wildlife of the region. The obverse prominently features a modern rendition of the traditional coat of arms of Greenland, depicting a standing polar bear, enclosed by the native lettering KALAALLIT NUNAAT, the word PRØVE (indicating a pattern or test piece), and the year 2010. The reverse displays a highly detailed illustration of a walrus, a quintessential symbol of the local marine fauna, accompanied by the denomination 10 KRONER. Although Greenland is an autonomous territory within the Kingdom of Denmark, this specific piece is an unofficial fantasy issue struck by Osborne Coinage in Cincinnati, USA, specifically for the collector market. Struck in solid brass, this round token features a plain edge, a diameter of 23.0 mm, a thickness of 1.94 mm, and a weight of 6.17 grams. Notably, this contemporary exonumia piece has a strictly limited mintage of only 10,000 sets worldwide.
