Schjöth, F., Chinese Currency, London 1976 reprint of 1929 original, 88 pages, 132 plates, hardcover, although a bit outdated now, it is reasonably comprehensive, has background information on the coinage, and a well-recognized, simple numbering system; the illustrations are simplified hand drawings which aid identification by novices, but do not reflect true calligraphy details. This book has decent sections on Chinese charms, Korean, Vietnamese, and Japanese cash, but not comprehensive enough for use today. It was the standard among Western collectors before Hartill, but is now essentially used for the numbering system, ex Dan Bloxsom Collection.
Estimate: 25- 45 USD
