franked with five Kwangsi Silver Yuan surcharged stamps, totaling 17 fen, tied by Kweilin cds, and arriving Canton on May 30, 1949. This cover correctly pays the special Kwangsi Postal District rate in effect from May to July 1949: 5 fen domestic postage, 8 fen registration fee, and 4 fen express fee, totaling 17 fen. At the time, postal rates in Kwangsi differed from the nationwide standard (contemporary rates being 4 fen domestic and 12 fen registration), reflecting the autonomy of local postal administrations during the early Silver Yuan period. A genuine example of a registered express cover under this special Kwangsi rate structure, it clearly illustrates regional postal practices and rate deviations, and is an important item for the study of local postal systems in the early Silver Yuan period, with solid exhibition and research value.

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.

franked with seven revenue stamps surcharged for use as basic postage and four Fukien overprinted basic stamps, eleven in total, paying 635 fen, all tied by Amoy cds. This cover correctly pays the special wartime foreign airmail rate imposed in the Amoy postal district: foreign surface letter rate of 15 fen for the first 20g plus 10 fen for each additional 20g, totaling 60 fen, together with an airmail fee of 40 fen per 10g totaling 560 fen, making 635 fen in all. Owing to wartime conditions and limited air transport capacity, the Amoy post office increased and adjusted airmail charges, including an additional 60 fen foreign base rate not consistent with nationwide tariffs, representing a local provisional rate. Addressed to an official institution in the Netherlands East Indies and weighing 140 grams, this is a heavy-weight airmail usage, clearly illustrating the special operation of outbound airmail services and local rate practices in wartime Fukien in 1949, of significant postal history and exhibition value.

franked with six stamps totalling 21 fen, tied by Tingshuiki cds. Five of Dr. SYS unit stamps bear “Tingshuiki” overprint, representing a local post office name overprint applied to basic stamps. Such overprints were introduced in the early Silver Yuan postal period to restrict inter-district usage of stamps, reflecting distinctive local postal practices. The cover correctly pays the 21 fen foreign airmail printed matter rate in effect at Tingshuiki from Jul 5 to Dec 15, 1949. This is the only recorded example of “Tingshuiki” overprint used on an outward foreign airmail printed matter cover, of great rarity. It combines the study of local overprint practices with foreign airmail usage, providing important evidence of regional postal operations during the transitional Silver Yuan period, and is of significant postal history and exhibition value.

franked with five 4 fen revenue stamps surcharged for use as basic postage and overprinted in blue with “Hanyuan,” tied by Hanyuan cds, with Chungking arrival marking of 38-8-17. The total franking of 20 fen correctly pays the registered rate in effect from Aug 1 to Sep 30, 1949, for 5 fen ordinary letter rate plus 15 fen registration fee. The “Hanyuan” overprinted stamps represent a typical example of local post offices applying their office names to basic stamps during the early Silver Yuan period, a provisional measure adopted to restrict inter-area usage amid currency instability and exchange disparities, reflecting strong regional postal characteristics. One of only three recorded covers bearing Sikang “Hanyuan” overprinted stamps, and the very example illustrated in Patrick Choy, China Silver Yuan Stamps (3rd Edition), page 195, Figure 5-24. A highly important and well-documented item illustrating the transitional postal operations of 1949, with significant postal history and exhibition value.
