謝爾頓等級：精確和標準化的硬幣分級

謝爾頓等級是針對鑄幣廠和精製硬幣的 70 分分級系統，由 William H. Sheldon 博士開發，用於評估硬幣品質。其範圍從較差 (PO-1) 到「完美」完好狀態 (MS-70)，中間等級代表不同程度的磨損。該等級已成為廣泛接受的硬幣評級標準，並被 PCGS 和 NGC 等主要評級公司所使用。

The Sheldon Scale: A Landmark Grading System for Numismatic Enthusiasts

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.

謝爾頓等級：錢幣愛好者的里程碑評級系統在錢幣的保存和升值至上的錢幣領域，謝爾頓等級是準確評估和分類硬幣不可或缺的工具。這種細緻的 70 分數字評級系統徹底改變了收藏家、經銷商和拍賣行評估錢幣狀況的方式，為確定其價值和需求提供了標準化框架。

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.

謝爾頓量表的起源謝爾頓量表的起源可以追溯到錢幣學領域著名專家William H. Sheldon 博士的細緻觀察。在 1949 年出版的開創性著作《Penny Whimsy》中，謝爾頓細緻地記錄了 18 世紀銅幣的狀況，為他開創性的評級系統奠定了基礎。

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.

等級的演變謝爾頓最初的分級等級主要集中在 19 世紀的大美分，隨著時間的推移經歷了完善和適應。沃爾特·布林 (Walter Breen) 是一位著名的錢幣研究者，也是謝爾頓 (Sheldon) 的親密夥伴，他在製定比例尺公式方面發揮了關鍵作用。經過他們的共同努力，謝爾頓分級系統發展成為一個適用於多種硬幣的綜合分級系統，超越了其最初關注的局限性。

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.

謝爾頓等級表的影響隨著錢幣市場渴望硬幣分級更加清晰和統一，謝爾頓等級表成為標準化的燈塔。美國錢幣協會 (ANA) 經過仔細審議並與其理事會協商後，於 1977 年採用了謝爾登數位分級標準，認識到其在提升硬幣分級實踐方面的巨大潛力。

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.

專業錢幣評級服務公司（PCGS）和錢幣擔保公司（NGC）等第三方評級服務機構的成立，進一步鞏固了謝爾頓等級在錢幣領域的主導地位。這些組織配備了訓練有素、經驗豐富的評級員團隊，精心地將謝爾頓等級應用於提交給專家評估的硬幣，並指定從 1 到 70 的數字等級。

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.

謝爾頓量表的出現對硬幣市場產生了深遠的影響，使收藏家、經銷商和投資者能夠自信地評估硬幣的狀況，將其與其他硬幣進行比較，並做出明智的購買決定。超過 1 億枚硬幣均採用謝爾頓等級封裝，它對錢幣領域的影響可謂是變革性的。

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.

了解謝爾頓等級的等級謝爾頓等級採用精確的數字系統（範圍從 1 到 70）對硬幣的狀況進行分類。每個等級對應一組特定的特徵，提供對硬幣保存情況的全面、客觀的評估。

Grades 1 to 58: Coins with Signs of Circulation

1 至 58 級：有流通跡象的硬幣

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.

評級在 1 到 58 之間的硬幣表現出不同程度的磨損，反映了它們的流通過程。隨著等級從差 (P) 升級到未流通 (AU) 58，流通的跡象變得不那麼明顯，在硬幣設計的最高點上只能看到最輕微的磨損。

Grades 60 to 70: Coins in Mint State

60 至 70 級：完好狀態的硬幣

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.

造幣廠 (MS) 硬幣的等級為 60 至 70，其特點是其原始狀態，沒有流通或後期生產缺陷的證據。此範圍內的最低等級 MS60 可能會出現輕微的處理痕跡或輕微的表面缺陷，而 MS70 則代表了保存的頂峰，即使在放大下，硬幣也沒有表現出明顯的缺陷。
