SinkiangRestricted for Use in SinkiangThe local currency fluctuated significantly against the national currency. Initially the currency was worth only one third of the national currency thus between 1915 and 1945 all stamps sold in this region were overprinted with the characters meaning "Restricted for use in Sinkiang" to prevent stamps being sent to other parts of China and sold for a profit. During the Second World War the currency had strengthened to being worth five times the national currency and, at this time, stamps were used at five times their face value. After August 1944 the circulation of national currency expanded into Sinkiang and the overprinted stamps were no longer necessary, however, they continued to be used until the supplies were exhausted. Thus from August 1944 to December 1945 covers bearing mixed frankings of regular and overprinted stamps are possible.1915 (7 Sept.) envelope to Holland marked "via Russia" bearing, on the reverse, 1915 2c.
