Bhutan 250 ngultrum 50 Years Calendar colored proof silver coin 2006

The Bhutan 250 Ngultrum “50 Years Calendar” 2006 silver coin is an ingenious blend of numismatic art and functionality. Issued by the Kingdom of Bhutan, it doubles as a working 50-year perpetual calendar covering the years 1995 to 2044. The obverse features a finely engraved rotating mechanism with months, years, and weekdays, accompanied by the inscription “Place Year Over Month – Calendar for 50 Yrs” and the denomination 250 Ngultrum with the year 2006. An anchor symbol decorates the left field, emphasizing stability and continuity, while red markings highlight leap years. The reverse showcases Bhutan’s intricate national emblem — two dragons encircling the sacred Dorji (Vajra) above a blooming lotus, surrounded by clouds and stars, with the legend “Kingdom of Bhutan.” Struck in .925 fine silver with an antique proof finish, this exceptional coin unites precision engineering with sacred symbolism — a rare collectible that merges timeless design with practical use.
