bearing a total of ten stamps, comprising six Silver Yuan unit stamps totaling 12 fen and four Gold Yuan stamps totaling $2,000,000. At the prevailing conversion rate of $250,000 to 1 Silver Yuan fen, the Gold Yuan franking equals 8 fen, making a total postage of 20 fen, correctly paying the domestic registered rate (rate period Aug 1 to Dec 8, 1949). Tied by Shihwantan cds dated 38.9.4 and arriving Chungking on Sep 9, 1949. This cover is of particular importance for its mixed franking of Silver Yuan and Gold Yuan stamps used at a very late stage, after the cessation of sale (July 20) and official invalidation (July 23) of Gold Yuan stamps. It represents an extremely late and rare practical usage, reflecting continued local postal acceptance and conversion handling under conditions of rapid currency transition. According to records, such late mixed-franking covers are exceedingly rare, and this example is regarded as one of the last recorded usages. It holds significant postal history and exhibition value for the study of post-war currency reform, rate conversion, and postal operations in the Southwest region.
