Jen, David, Chinese Cash: Identification and Price Guide, Iola, Wisconsin, USA, 2000, Krause Publications, 341 pages, softcover, a general catalog on Chinese coins, including some Central Asian material (Sogdian, Turgic Khaganate, etc.) and Xinjiang/Sinkiang. The organization of the book is confusing and hard to use, and it does not cover all of the types in Schjoth or Fisher's Ding. It does reference Schjoth and FD numbers if they exist. The sections on Wu Shu, Pan Liang and other early types are decent.
Estimate: 20-40 USD
