拍品描述： China - Tibet. TIBET: AR tangka, Y-31, struck in 1953-54, a superb example! PCGS graded MS63. An undated silver coin in the style of the earlier ga-den tangkas was struck on modern coin presses in 1953 and 1954 for distribution to monks. It is the last silver coin which was issued in Tibet, and it circulated at the value of 5 srang, although its design is that of a tangka. The reverse depicts a wheel with eight spokes representing the "wheel of law" which was set in motion by the Buddha. In the center of the wheel two comma-shaped elements represent what the Tibetans call norbu dga khyil (whorling jewel of joy). This coin was struck in high grade silver and had the popular name tangka dkar-po gsar pa (new white tangka).
