{"product_id":"tang-dynasty-qian-yuan-zhong-bao-cash-coins","title":"Tang Dynasty Qian Yuan Zhong Bao Cash Coins","description":"\u003cp\u003eChinaÕs Tang Dynasty, lasting for 289 years from 618 to 907 AD, was a golden age, when literature, art, technological innovation, and trade flourished. To support a currency-based economy for a population that numbered 80 million by the end of the dynasty, two main series of bronze cash coins were produced in the millions, one of which bears the inscription ____ _Qian Yuan Zhong Bao; QYZB). The foremost previous reference on QYZB is Ken Gen Jž H™ Senfu (2005) by Sh™ji Yoshida, written in Japanese.\u003c\/p\u003e \n\n\u003cp\u003eWhile generally following YoshidaÕs classification, this guide documents more of the fine-scale variation in the main groups of QYZB. It begins with introductory material on the historical context of the coins, their method of production, what defines a variety, fake QYZB, and terminology and identifying features. One short appendix discusses whether and how to clean cash coins, and another presents guidelines for purchasing them on the Internet.\u003c\/p\u003e \n\n\u003cp\u003eThe body of the guide lists 457 varieties or variants of mostly value-1 (\u0026lt; 26 mm in diameter) coins lacking a reverse mark, with original rubbings from 461 coins, including 44 entries for small, privately cast coins having a reverse ring. A detailed description of identifying features accompanies each set of rubbings. While this guide treats many plain-reverse varieties not appearing in YoshidaÕs book, the converse is also true. People attempting to identify value-1 QYZB will need both guides and will undoubtedly still encounter coins not attributable in either, because much remains to be learned about value-1 QYZB.\u003c\/p\u003e","brand":"BooksWholesale","offers":[{"title":"Paperback","offer_id":44349792026785,"sku":"9780991035618","price":34.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0462\/1120\/3233\/files\/869ygp-front-shortedge-384.jpg?v=1716214455","url":"https:\/\/bookswholesale.myshopify.com\/products\/tang-dynasty-qian-yuan-zhong-bao-cash-coins","provider":"BooksWholesale","version":"1.0","type":"link"}
