bearing a total of sixteen stamps, tied by Sining cds. The franking includes ten Gold Yuan stamps with a total face value of 5,000,000, converted at the contemporary rate to 64 fen in Silver Yuan currency, together with six Revenue Surcharged Silver Yuan stamps totaling 51 fen, making an overall postage of 115 fen. This correctly pays the foreign double-weight registered airmail rate applicable to the Northwestern region for the period Jul 5 to Sep 5, 1949. Of particular significance is the mixed franking of Gold Yuan and Silver Yuan issues, clearly illustrating the transitional currency conversion practices during a period of rapid monetary change, especially as applied in the Northwestern postal system. Such international registered airmail covers bearing mixed currency franking are of extreme rarity, with only one recorded example. The cover shows clear cancellations and a complete rate structure, providing an outstanding illustration of postwar currency reform, exchange conversion, and long-distance airmail operations, and is of considerable importance for postal history study and exhibition.
