Soviet YSK $ w/o - c/s

Listed in the Dec. 2010 Ponterio HK sale of the Wa She Wong collection (lot # 341) as an issue of the Chinese Communist Party to be used to purchase goods in Nationalist Chinese areas. The use of Soviet Red Army issues was illegal in these areas and could mean death to those is posession. Unlisted in KM, L&M listed # 899. It would take an experienced collector to determine these from the myriad of other YSK types. This coin, the only documented example I have ever seen, sold for a total of $5463.
