Also known as a peacock rupee. The coin was struck in 1852 CE (1214 Burmese era) That's when King Mindon Min ascended the throne. The peacock emblem was the kings' personnel symbol. Made of 0.9170 fine silver and weighs about 11.66 grams. I think it has a dye crack on the reverse. (see Pictures) KM#10 EF 125 B/O
