谢尔顿等级：精确和标准化的硬币分级

谢尔顿等级是针对铸币厂和精制硬币的 70 分分级系统，由 William H. Sheldon 博士开发，用于评估硬币质量。其范围从较差 (PO-1) 到“完美”完好状态 (MS-70)，中间等级代表不同程度的磨损。该等级已成为广泛接受的硬币评级标准，并被 PCGS 和 NGC 等主要评级公司所使用。

In the realm of numismatics, where the preservation and appreciation of coins reign supreme, the Sheldon Scale stands as an indispensable tool for accurately evaluating and classifying coins. This meticulous 70-point numerical grading system has revolutionized the way collectors, dealers, and auction houses assess the condition of coins, providing a standardized framework for determining their value and desirability.

谢尔顿等级：钱币爱好者的里程碑式评级系统在钱币的保存和升值至上的钱币领域，谢尔顿等级是准确评估和分类硬币不可或缺的工具。这种细致的 70 分数字评级系统彻底改变了收藏家、经销商和拍卖行评估钱币状况的方式，为确定其价值和需求提供了标准化框架。

The Genesis of the Sheldon Scale

The genesis of the Sheldon Scale can be traced back to the meticulous observations of Dr. William H. Sheldon, a renowned expert in the field of numismatics. In his seminal work, "Penny Whimsy," published in 1949, Sheldon meticulously documented the condition of 18th-century copper coins, laying the groundwork for his groundbreaking grading system.

谢尔顿量表的起源谢尔顿量表的起源可以追溯到钱币学领域著名专家William H. Sheldon 博士的细致观察。在 1949 年出版的开创性著作《Penny Whimsy》中，谢尔顿细致地记录了 18 世纪铜币的状况，为他开创性的评级系统奠定了基础。

The Evolution of the Scale

Sheldon's initial grading scale, primarily focused on 19th-century large cents, underwent refinement and adaptation over time. Walter Breen, a prominent numismatic researcher and close associate of Sheldon, played a pivotal role in developing the formula for the scale. Through their combined efforts, the Sheldon Scale evolved into a comprehensive grading system applicable to a wide array of coins, transcending the limitations of its original focus.

等级的演变谢尔顿最初的分级等级主要集中在 19 世纪的大美分，随着时间的推移经历了完善和适应。沃尔特·布林 (Walter Breen) 是一位著名的钱币研究者，也是谢尔顿 (Sheldon) 的亲密伙伴，他在制定比例尺公式方面发挥了关键作用。经过他们的共同努力，谢尔顿分级系统发展成为一个适用于多种硬币的综合分级系统，超越了其最初关注的局限性。

The Impact of the Sheldon Scale

As the numismatic market yearned for greater clarity and uniformity in coin grading, the Sheldon Scale emerged as a beacon of standardization. The American Numismatic Association (ANA), after careful deliberation and consultation with its Board of Governors, adopted the Sheldon Numerical Grading Scale in 1977, recognizing its immense potential to elevate the practice of coin grading.

谢尔顿等级表的影响随着钱币市场渴望硬币分级更加清晰和统一，谢尔顿等级表成为标准化的灯塔。美国钱币协会 (ANA) 经过仔细审议并与其理事会协商后，于 1977 年采用了谢尔登数字分级标准，认识到其在提升硬币分级实践方面的巨大潜力。

The establishment of third-party grading services, such as Professional Coin Grading Service (PCGS) and Numismatic Guarantee Corporation (NGC), further solidified the dominance of the Sheldon Scale in the numismatic arena. These organizations, armed with teams of highly trained and experienced graders, meticulously apply the Sheldon Scale to coins submitted for their expert evaluation, assigning numerical grades ranging from 1 to 70.

专业钱币评级服务公司（PCGS）和钱币担保公司（NGC）等第三方评级服务机构的成立，进一步巩固了谢尔顿等级在钱币领域的主导地位。这些组织配备了训练有素、经验丰富的评级员团队，精心地将谢尔顿等级应用于提交给专家评估的硬币，并指定从 1 到 70 的数字等级。

The advent of the Sheldon Scale has profoundly influenced the coin market, enabling collectors, dealers, and investors to confidently assess the condition of coins, compare them to others, and make informed purchasing decisions. With over 100 million coins encapsulated using the Sheldon Scale, its impact on the numismatic landscape has been nothing short of transformative.

谢尔顿量表的出现对硬币市场产生了深远的影响，使收藏家、经销商和投资者能够自信地评估硬币的状况，将其与其他硬币进行比较，并做出明智的购买决定。超过 1 亿枚硬币均采用谢尔顿等级封装，它对钱币领域的影响可谓是变革性的。

Understanding the Grades of the Sheldon Scale

The Sheldon Scale employs a precise numerical system, ranging from 1 to 70, to categorize the condition of coins. Each grade corresponds to a specific set of characteristics, providing a comprehensive and objective assessment of the coin's preservation.

了解谢尔顿等级的等级谢尔顿等级采用精确的数字系统（范围从 1 到 70）对硬币的状况进行分类。每个等级对应一组特定的特征，提供对硬币保存情况的全面、客观的评估。

Grades 1 to 58: Coins with Signs of Circulation

1 至 58 级：有流通迹象的硬币

Coins graded between 1 and 58 exhibit varying degrees of wear and tear, reflecting their journey through circulation. As the grade progresses from Poor (P) to About Uncirculated (AU) 58, the evidence of circulation becomes less pronounced, with only the slightest amount of wear visible on the highest points of the coin's design.

评级在 1 到 58 之间的硬币表现出不同程度的磨损，反映了它们的流通过程。随着等级从差 (P) 升级到未流通 (AU) 58，流通的迹象变得不那么明显，在硬币设计的最高点上只能看到最轻微的磨损。

Grades 60 to 70: Coins in Mint State

60 至 70 级：完好状态的硬币

Mint State (MS) coins, graded from 60 to 70, are characterized by their pristine condition, with no evidence of circulation or post-production flaws. The lowest grade within this range, MS60, may exhibit minor handling marks or slight surface imperfections, while MS70 represents the pinnacle of preservation, with coins exhibiting no discernible flaws even under magnification.

造币厂 (MS) 硬币的等级为 60 至 70，其特点是其原始状态，没有流通或后期生产缺陷的证据。此范围内的最低等级 MS60 可能会出现轻微的处理痕迹或轻微的表面缺陷，而 MS70 则代表了保存的顶峰，即使在放大下，硬币也没有表现出明显的缺陷。
