Grading Chinese Cash Coins: The Difference Between $10 and $1,000

Condition is Everything: How to Grade Chinese Cash Coins

When examining these three Chinese cash coins, the difference between a $10 find and a $1,000 treasure often comes down to subtle details that only experienced graders can identify. Let me walk you through the critical aspects of grading these fascinating pieces of Asian numismatic history.

Historical Context and Identification

Before diving into the grading specifics, let’s establish what we’re looking at. The top coin is a Chinese Qianlong emperor piece (1736-1795), identified as KM391. The bottom coin appears to be from the Daoguang emperor era (1820-1850), both minted at the Board of Works mint. The middle coin, interestingly, is not Chinese at all but rather a Japanese piece.

Understanding the Basics of Cash Coin Grading

Chinese cash coins present unique grading challenges compared to Western coins. These copper or bronze pieces were mass-produced using crude methods, meaning strike quality varies significantly even within the same issue. When grading these coins, we must consider several factors:

• Wear patterns on the high points of characters
• Original surface luster and patina
• Strike quality and centering
• Eye appeal and overall preservation
• Presence of verdigris or corrosion

Examining the Qianlong Coin (Top)

The Qianlong emperor coin shows considerable wear on the high points of the characters. In grading terms, this places it in the Fine to Very Fine range. The key diagnostic areas to examine are:

The four characters on the obverse should show the center portions of each character clearly, with the outer strokes still visible but potentially merged on the highest points.

For PCGS and NGC standards, a coin in this condition would likely grade between F12 and VF20. The presence of original red-brown patina would add significant eye appeal and potentially increase the grade by one level.

Wear Patterns to Look For

On the Qianlong piece, examine the following areas:

• The inner portions of the “Qian” character
• The central areas of “Long”
• The bottom portions of “Bao”
• The inner curves of “Zhong”

The more detail remaining in these areas, the higher the grade. A coin where all four characters show clear inner details would be considered Very Fine or better.

Analyzing the Daoguang Coin (Bottom)

The Daoguang emperor coin presents a more challenging assessment due to the darker photographs. However, based on the visible details, this piece appears to be in slightly better condition than the Qianlong coin, possibly grading VF25 to VF30.

Luster and Surface Preservation

Chinese cash coins from the early 19th century often retain original mint luster in protected areas. Look for:

• Reddish highlights in the recesses between characters
• Smooth, undisturbed patina on the reverse
• Absence of verdigris (green corrosion) in the character depressions

The presence of original luster can significantly impact value. A coin that retains 50% or more of its original surface quality might grade one level higher than a technically similar but heavily toned piece.

The Japanese Coin: A Brief Note

While not Chinese, the middle coin represents an interesting comparison. Japanese cash coins from the same period often show superior strike quality due to different minting techniques. When grading Japanese pieces, pay attention to:

• The sharpness of the inner details of the central hole
• The definition of the chrysanthemum emblem on the reverse
• The overall symmetry and centering of the design

PCGS/NGC Standards for Ancient and Medieval Coins

When submitting these coins to major grading services, keep in mind that standards differ from modern coins:

PCGS and NGC typically use broader grade ranges for ancient and medieval coins, with many pieces falling into the “Fine” to “Very Fine” categories rather than the Mint State grades common with modern coinage.

For Chinese cash coins specifically, the services often provide detailed attribution and may note special characteristics like “red-brown surfaces” or “choice patina” that can enhance value.

Market Value Considerations

Based on the apparent condition of these three coins:

• The Qianlong piece (F12-VF20): $15-45 retail value
• The Daoguang piece (VF25-VF30): $25-75 retail value
• The Japanese coin: Value depends on specific type, but similar condition pieces range $20-60

Exceptional examples with original surfaces, rare mint marks, or historical significance could command 5-10 times these values.

Authentication Tips

When examining Chinese cash coins, watch for these authentication markers:

• Correct calligraphy style for the period
• Appropriate casting or striking characteristics
• Natural patina progression consistent with age
• Metal composition matching known issues

Conclusion: The Art and Science of Grading

Grading Chinese cash coins requires both technical knowledge and an experienced eye. The subtle differences between a Fine-12 and Very Fine-20 example can mean hundreds of dollars in value. Always examine coins in proper lighting, use magnification for character details, and when in doubt, consult with experienced graders or reputable dealers. Remember that original surfaces and eye appeal often matter as much as technical wear when determining a coin’s true grade and market value.
