Understanding the Premium of Plus-Grade AU Bust Halves
Condition is everything. Here’s how to examine the high points and fields to determine the true grade of these exceptional coins.
When evaluating Bust Half Dollars, particularly those in the AU (About Uncirculated) range, the difference between a standard AU and a Plus-grade AU can mean thousands of dollars. For collectors specializing in Plus-grade AU Bust Halves, understanding the nuances of wear patterns, luster preservation, strike quality, and overall eye appeal is essential.
The Anatomy of a Plus-Grade AU Bust Half
Bust Half Dollars were struck from 1794 to 1839, and their design features several high points that collectors and graders examine closely. These include Liberty’s hair curls, the eagle’s breast feathers, and the wreath details on the reverse. In a Plus-grade AU coin, these high points should show only the slightest friction, with most of the original mint luster still visible in the protected areas.
The key to identifying a true AU58+ versus a standard AU55 or AU58 lies in the preservation of luster and the absence of significant marks. According to PCGS and NGC standards, a Plus-grade coin must exhibit exceptional eye appeal for its grade, with minimal contact marks and strong original surface characteristics.
Wear Patterns and Luster Preservation
When examining a Bust Half for Plus-grade potential, pay close attention to the wear patterns. The hair above Liberty’s forehead and behind her ear are typically the first areas to show friction. In a true AU58+, these areas should display only the faintest traces of wear, with the underlying luster still visible under proper lighting.
The eagle’s breast is another critical area. In circulated coins, this is often one of the first places to show wear. For Plus-grade consideration, the breast feathers should maintain their original detail with only minimal flattening. The luster in the recesses between the feathers should be well-preserved, creating contrast between the protected areas and the slightly worn high points.
Strike Quality Considerations
Bust Halves are known for their variable strike quality, as they were hand-fed into screw presses. When evaluating for Plus-grade status, consider the overall strike. A well-struck coin with full details in the hair curls, eagle’s feathers, and wreath will always command a premium over a weakly struck example, even if both are technically in the same numerical grade.
The centers of Bust Halves are often weakly struck due to the limitations of 19th-century minting technology. However, a Plus-grade example should show at least average or better strike characteristics, with Liberty’s facial features and the eagle’s eye clearly defined.
Eye Appeal and Surface Preservation
Eye appeal is perhaps the most subjective but important factor in Plus-grade designation. A Bust Half worthy of a Plus designation should exhibit original surfaces with attractive toning or, in the case of dipped coins, even, natural-looking luster. Avoid coins with harsh cleaning marks, heavy abrasions, or unattractive dark toning that obscures the design details.
The fields should be relatively mark-free, with any contact marks limited to inconspicuous areas. Remember that Bust Halves circulated heavily in commerce, so finding examples with pristine surfaces is challenging. However, for Plus-grade consideration, the marks present should be minimal and not detract from the overall appearance.
PCGS and NGC Plus-Grade Standards
Both PCGS and NGC use the Plus-grade designation to recognize coins that are high-end for their numerical grade. For Bust Halves, this means an AU58+ should be approaching Mint State quality in terms of luster and eye appeal, with only the slightest actual wear on the highest points.
When submitting coins for Plus-grade consideration, ensure they meet the following criteria:
- Exceptional luster preservation for the grade
- Minimal contact marks, especially in prime focal areas
- Above-average strike for the issue
- Overall eye appeal that exceeds typical examples of the grade
Market Premiums and Investment Potential
The market recognizes the scarcity and desirability of Plus-grade Bust Halves. A coin graded AU58+ can command 50-100% premiums over a standard AU58, and in some cases even more. This premium reflects both the rarity of finding well-preserved examples and the increased demand from sophisticated collectors who understand the value of condition rarities.
When building a collection of Plus-grade AU Bust Halves, focus on quality over quantity. It’s better to own one exceptional coin than several mediocre examples. Look for coins with original surfaces, attractive toning, and minimal marks. Consider working with reputable dealers who specialize in early American coinage and understand the nuances of grading these challenging series.
Authentication and Certification
Given the value premium associated with Plus-grade Bust Halves, authentication becomes crucial. Always purchase coins certified by PCGS or NGC, as these services have established grading standards and provide a level of protection against counterfeiting and overgrading. Be wary of raw coins or those in less-reputable holders, especially when dealing with high-value Plus-grade examples.
When examining certified coins, verify that the holder displays the Plus designation clearly. Some older holders may not indicate Plus grades, so it’s worth checking the certification number online to confirm the complete grade attribution.
Conclusion
Collecting Plus-grade AU Bust Halves represents both a challenge and an opportunity for serious numismatists. The combination of historical significance, aesthetic appeal, and condition rarity makes these coins particularly desirable. By understanding the grading nuances, focusing on quality examples, and working with knowledgeable professionals, collectors can build meaningful collections that will appreciate in both historical and monetary value over time.
Remember that condition is indeed everything in numismatics. The difference between a standard AU and a Plus-grade example often comes down to subtle details that only become apparent with experience and careful study. Take your time, examine many coins, and develop an eye for what makes a truly exceptional Bust Half worthy of the Plus designation.
