Lot# 9034

franked with four Yunnan Half-Value Silver Yuan Basic stamps totaling 120 fen, tied by Kunming cds. This cover was sent under the Yunnan postal district’s half-value Silver Yuan rate system implemented from May 10, 1949, adopted due to the difference in silver content of locally used currency. The total franking of 120 fen correctly pays the foreign airmail rate in effect at the time. The half-value Silver Yuan stamps were issued on May 12, 1949, making this an early usage example. One of the earliest recorded foreign airmail covers under the Yunnan half-value Silver Yuan system, clearly illustrating the impact of regional monetary conditions on postal rates, and the operation of international airmail service in the early Silver Yuan period, of significant postal history and exhibition value.
