Q: What is a Lace Kaiyuan Tongbao coin?
A: A Lace Kaiyuan Tongbao coin refers to a Tang Dynasty Kaiyuan Tongbao (開元通寶) cash coin that features a distinctive lace-like or openwork design, typically created by cutting away portions of the metal to leave an intricate pattern. According to the Shanghai Museum's Chinese Coin Gallery documentation, such openwork coins were often produced as charms or ornaments rather than circulating currency, and they are rare variants of the standard Kaiyuan Tongbao issued from 621 CE onward. The official catalogue 'Zhongguo Qianbi Da Cidian' notes that lace coins usually retain the four-character inscription but with modified rims or inner holes, making them highly collectible among numismatists.
Q: Where can I find official images of Lace Kaiyuan Tongbao coins?
A: Official images of Lace Kaiyuan Tongbao coins are available from the National Museum of China's online collection and the Shanghai Museum's digital numismatic archive. The National Museum of China's website provides high-resolution photographs of Tang Dynasty coins, including openwork variants, under its 'Ancient Chinese Coins' section. Additionally, the American Numismatic Society (ANS) maintains a searchable database, 'MANTIS', which includes images of Kaiyuan Tongbao lace coins donated by private collectors, with catalog numbers and provenance. For academic use, the 'Zhongguo Lidai Huobi Daquan' published by the People's Bank of China contains plate images. Always verify authenticity with a certified numismatic authority before relying on any image for research.
Q: What are the typical design features of Lace Kaiyuan Tongbao coin images?
A: Typical design features in images of Lace Kaiyuan Tongbao coins include a circular outer rim with a central square hole, where the metal between the rim and the hole is cut into openwork patterns such as floral, geometric, or cloud motifs. The four Chinese characters '開元通寶' are usually still legible on the remaining metal, though sometimes stylized. According to the British Museum's online collection notes, these lace coins often show a thinner body and sharper edges compared to standard issues. The obverse typically bears the inscription, while the reverse may be plain or have crescent marks. Official reports from the China Numismatic Museum emphasize that the openwork technique was likely done post-minting, making each piece unique.
Q: Are Lace Kaiyuan Tongbao coins considered rare or valuable?
A: Yes, Lace Kaiyuan Tongbao coins are considered rare and valuable. The China Numismatic Museum's 'Rare Chinese Coins' report classifies openwork Kaiyuan Tongbao as 'Grade 2' rarities, meaning fewer than 100 known examples. In auction records cited by the China Guardian Auctions, a fine lace Kaiyuan Tongbao can fetch between 50,000 and 200,000 RMB, depending on condition and provenance. Their value stems from both historical significance and artistic craftsmanship, as they were likely produced in limited quantities for ceremonial or decorative use. However, due to forgeries, authentication by the China Numismatic Society or similar official body is essential before any transaction.
Q: How were Lace Kaiyuan Tongbao coins produced according to official reports?
A: According to the 'Zhongguo Gudai Qianbi Zaoqi Jishu Yanjiu' published by the Chinese Academy of Sciences, Lace Kaiyuan Tongbao coins were not minted as openwork pieces originally; instead, standard Kaiyuan Tongbao coins were modified after casting. Artisans used fine chisels or saws to cut away metal, creating lace-like patterns, a technique known as 'openwork carving' (鏤空雕刻). This was labor-intensive and often done in workshops outside official mints, possibly for temple offerings or personal adornment. The report notes that some examples show traces of filing and polishing. Because the process was manual, no two lace coins are identical, and official mint records do not mention their production.
Dialogue about
Common scenarios of "Lace Kaiyuan Tongbao coin images"
【Coin Collector】 Hey, I've been trying to identify a Lace Kaiyuan Tongbao coin I inherited. Can you tell me what makes the 'lace' version special?
【Numismatist】 The Lace Kaiyuan Tongbao is a rare variety of the Tang Dynasty Kaiyuan Tongbao. 'Lace' refers to the delicate, intricate patterns on the coin's surface, often resembling lacework. These patterns were likely created by a special minting technique or post-mint carving.
【Coin Collector】 Interesting! I've seen images online, but they vary a lot. What should I look for in authentic lace patterns?
【Numismatist】 Authentic lace patterns are fine, symmetrical, and consistent. They often feature floral or geometric motifs. Counterfeits tend to have blurry or irregular patterns. Also, check the coin's patina and wear—genuine ones show age-related wear on the high points.
【Coin Collector】 Can you describe the typical obverse and reverse designs of a Lace Kaiyuan Tongbao?
【Numismatist】 The obverse usually has the four characters 'Kai Yuan Tong Bao' in regular script, arranged top-bottom-right-left. The reverse may have a crescent moon or other symbols, but the lace pattern is often on the rim or around the characters. Some have lace on both sides.
【Coin Collector】 I've heard that some Lace Kaiyuan coins have a silver or gold content. Is that true?
【Numismatist】 Yes, some rare examples are made of silver or gold, but most are bronze. The silver and gold ones were likely presentation pieces or special issues. If yours is silver-colored, it could be silver or a silver-coated bronze. A specific gravity test or XRF analysis can confirm.
【Coin Collector】 How can I tell if my coin's lace pattern is genuine and not a modern reproduction?
【Numismatist】 Look for tool marks under magnification. Ancient carving would have irregular, hand-made cuts, while modern laser or acid etching leaves uniform patterns. Also, the patina should be integrated into the lace crevices; if it's only on the surface, it's likely fake.
【Coin Collector】 Are there any known reference books or catalogs for Lace Kaiyuan Tongbao images?
【Numismatist】 Yes, 'Zhongguo Guqian Dacidian' by Ding Fubao has some, but the most comprehensive is 'Kaiyuan Tongbao Pu' by Zhang Hongming. Also, the Shanghai Museum and National Museum of China have online databases with high-resolution images.
【Coin Collector】 I've noticed that some images show the lace pattern only on the rim, while others have it around the characters. Does that indicate different subtypes?
【Numismatist】 Absolutely. There are two main subtypes: rim-lace and field-lace. Rim-lace has patterns on the outer edge, while field-lace has them on the flat area around the characters. Field-lace is rarer and more valuable.
【Coin Collector】 What's the historical context of these coins? Were they made during a specific period?
【Numismatist】 They were likely produced during the reign of Emperor Xuanzong of Tang (713-741 AD), during the Kaiyuan era. Some scholars believe they were minted for special occasions like the emperor's birthday or military victories.
【Coin Collector】 I've seen some with a square hole and others with a round hole. Is that significant?
【Numismatist】 Kaiyuan Tongbao typically have a square central hole. Round holes are extremely rare and might be errors or later alterations. If you see a round hole, be suspicious—it's likely a fake or a modified coin.
【Coin Collector】 How much does a genuine Lace Kaiyuan Tongbao typically sell for at auction?
【Numismatist】 Prices vary widely. Common bronze ones in fine condition can go for $500-$2000. Silver ones can fetch $10,000-$50,000. Extremely rare gold or perfect condition examples have sold for over $100,000. But always buy from reputable dealers with authentication.
【Coin Collector】 Thanks for all the info! I'll take my coin to a professional to verify. One last question: are there any online forums or communities dedicated to Lace Kaiyuan Tongbao?
【Numismatist】 Yes, the Chinese Coin Forum (ChineseCoinForum.com) and the Ancient Coin Collectors Guild (ACCG) have active sections. Also, Facebook groups like 'Tang Dynasty Coins' are helpful. Share clear images and ask for opinions—experts are usually willing to help.
