franked with six examples of Tsingtao Silver Yuan overprinted stamps, paying a total of 26 fen, tied by Tsingtao cds “38.5.21”. The franking correctly pays the combined domestic airmail, express and registration rate of 26 fen in effect at the time. The cover from Tsingtao to Foochow illustrates airmail transmission between East China and the southeast coastal region. At this period, Tsingtao was temporarily cut off from the central postal system and stamp supplies, and the local post office overprinted and issued its own “Tsingtao” Silver Yuan stamps as a provisional measure to meet postal needs. This cover represents a genuine usage of Tsingtao overprinted Silver Yuan stamps on a domestic expressed airmail registered item, demonstrating the combined use of multiple postal services (airmail, express and registration), and reflecting the practical operation of local postal services during the transitional early Silver Yuan period, of postal history and exhibition interest.

franked with six examples of East Szechwan (Chungking) Postal District Silver Yuan surcharged stamps, paying a total of 30 fen, tied by Chengtu (Ting I) cds “38.10.15”, and with arrival Chungking Oct 18. The franking correctly pays the domestic airmail registered rate of 30 fen for Chengtu in effect from Aug 1 to Dec 27, 1949. The East Szechwan Postal District issued Silver Yuan surcharged stamps during the early Silver Yuan period to meet postal accounting needs following the discontinuation of the Gold Yuan.

franked with one West Szechwan domestic ordinary unit stamp (5 fen) overprinted on a high value $3,000,000 stamp, together with eight basic stamps, paying a total of 35 fen, tied by Weiyuan cds “38.10.26”, and with arrival Chungking Nov 1. The franking correctly pays the domestic double registered rate of 35 fen for Weiyuan in effect from Aug 1 to Dec 6, 1949. The use of a high-denomination $3,000,000 stamp surcharged to serve as a unit stamp reflects a provisional measure during the Silver Yuan transitional period, when stamp supplies were insufficient and existing high value stamps were adapted for postal use. This cover represents a genuine mixed franking of a surcharged high-value unit stamp and basic stamps paying the double registered rate, clearly illustrating the complexities of postal operations and stamp usage during the transitional period, and is of postal history and exhibition interest.

Yuyang came under CCP control on Nov 11, 1919, making this an example used prior to the political transition. Ilustrated in Patrick Choy, China Silver Yuan Stamps (3rd Edition), page 35, Figure 1-18, it possesses clear literature provenance. A representative item of Silver Yuan transitional postal history, with exhibition and research value.

The Fukien Postal District issued Basic stamps in May 1949, in both handstamped and machine surcharged types, produced by surcharging Gold Yuan stamps to meet postal needs during the Silver Yuan transitional period; mixed frankings of different types are commonly encountered on commercial mail. This cover illustrates the actual operation of outward printed matter mail in the early Silver Yuan postal period and possesses solid postal history and exhibition value.
