How to Identify Chinese Coins
Identifying a Chinese coin is mostly a process of elimination: read what you can, measure what you cannot, and match the result against a reference. This guide covers the checks that matter most for Chinese coins — and the shortcut that turns hours of catalog browsing into seconds.
What counts as Chinese coins?
Chinese coinage divides into two great traditions. For over two thousand years China cast round coins with square central holes — cash coins — from the Ban Liang of the Qin dynasty and the Han Wu Zhu through the reign-title coins that began with the Tang Kaiyuan Tongbao and ran to the end of the Qing dynasty in 1911. From the late 1800s, machine-struck silver dragon dollars, copper cents and Republican coinage joined and then replaced the cast tradition.
Cash coins are identified by their four obverse characters, which name the emperor’s reign title. Qing-dynasty issues add Manchu-script mint marks on the reverse, which pin down where a coin was cast.
Step-by-step: identifying Chinese coins
You need good light, a digital scale that reads to 0.1 g, calipers if you have them, and a 5x–10x loupe. With those on hand, here is how to identify Chinese coins:
- For a square-holed cash coin, read the four obverse characters in the order top, bottom, right, left: most give a reign title followed by tongbao (通寶), meaning “circulating treasure.”
- Match the reign title to its dynasty and dates — Kangxi Tongbao means 1662–1722 and Qianlong Tongbao 1736–1795, both Qing dynasty.
- Check the reverse: Qing cash carries Manchu-script mint marks (Boo Chiowan is the Board of Revenue mint in Beijing), while many earlier dynasties left the reverse blank.
- For machine-struck silver, look for the dragon: provincial dragon dollars and their fractions (late 1800s–1911) name the province in both Chinese and English.
- Weigh and measure: ordinary Qing cash runs roughly 3.5–5 g at 22–28 mm, and a dragon dollar should weigh about 26.6–27 g — deviations are a major fake alarm.
- Cross-reference cast coins with Hartill’s Cast Chinese Coins or Numista, and struck coinage with Krause or L&M numbers.
Are Chinese coins valuable?
Common Qing cash coins are among the cheapest collectibles in numismatics at $1–5 each, with scarcer mints, rebel issues and large multiple-cash pieces worth more. Machine-struck silver is the opposite story: genuine dragon dollars and Republican dollars commonly bring $100 to several thousand — which is exactly why they are the most counterfeited coins in the world.
Treat any figure you read as a starting point rather than a quote. What a specific piece brings depends on its grade, its rarity and its eye appeal, and the only reliable comparison is recent sold results for equivalent examples. The catalogue price per grade in AI Coin Collector is a reference point, not a sale price.
Common pitfalls and fakes
These are the mistakes that cost collectors the most money with Chinese coins:
- Replica dragon dollars are everywhere: wrong weight, slightly magnetic alloys and cast surfaces expose most of them.
- Feng shui charm strings sold in gift shops are modern reproductions of cash coins, not antiques.
- Amulets and charms with auspicious phrases are often mistaken for coins — genuine cash names a reign title.
- Claims of rare “mother coins” (engraved masters used to cast others): genuine ones are exceptional rarities, and nearly all offered online are ordinary or fake.

Frequently asked questions
How do I identify Chinese coins?
For a square-holed cash coin, read the four obverse characters in the order top, bottom, right, left: most give a reign title followed by tongbao (通寶), meaning “circulating treasure.” Match the reign title to its dynasty and dates — Kangxi Tongbao means 1662–1722 and Qianlong Tongbao 1736–1795, both Qing dynasty. Working through checks like these in order narrows down most pieces quickly — and a clear photo in AI Coin Collector turns the whole process into a few seconds.
How do I read a Chinese cash coin?
Read the four characters around the square hole in the order top, bottom, right, left. The first two give the emperor’s reign title and the last two are usually tongbao, “circulating treasure.” Match the reign title to a dynasty list and check the reverse for Qing-era Manchu mint marks.
Are Chinese coins worth anything?
Common cash coins bring only $1–5, but scarcer cast issues climb, and genuine Chinese silver dollars run from about $100 into the thousands. Because of those prices, Chinese silver is heavily faked — authentication matters more than in almost any other series.
Can an app identify Chinese coins from a photo?
Yes. AI Coin Collector identifies coins, tokens and medals from a single photo using our own AI vision model, estimates condition on the Sheldon 1–70 scale, and shows the Numista catalogue price per grade.
