水牛鎳幣非常受歡迎，但一個小細節就能區分價值幾百美元和超過 10 萬美元的鎳幣

這些稀有的鎳幣是美國於 1913 年至 1938 年間鑄造的。硬幣的背面有一頭水牛。

A die break, also known as a cud, is an error on a coin that is formed when a die, (a metallic piece that is used to strike a coin) is missing a piece near the rim.

模具斷裂，也稱為反芻，是當模具（用於撞擊硬幣的金屬片）在邊緣附近缺少一塊時形成的硬幣上的錯誤。

When dies strike coins, they have a heavy impact and pressure and the metal from the blank part of the coin, known as the planchet, overlaps the area left by the missing piece of the die.

當模具撞擊硬幣時，它們會產生很大的衝擊力和壓力，並且硬幣空白部分（稱為毛坯）的金屬與模具缺失部分留下的區域重疊。

Coins with such deformities are rare thanks to the strict quality control measures at the US Mint.

由於美國造幣廠嚴格的品質控制措施，出現這種畸形的硬幣很少見。

When such errors do occur, they are often caught and destroyed.

當此類錯誤確實發生時，它們通常會被捕獲並銷毀。

However, those that slip through the net become huge collector's items worth much more than their face value.

然而，那些漏網之物卻成為了龐大的收藏品，其價值遠高於其面值。

An error at the Denver mint led to thousands of nickels being minted, and the buffalo was missing one of its legs.

丹佛鑄幣廠的一次失誤導致鑄造了數千枚鎳幣，而水牛也失去了一條腿。

"The 1937-D 3 Legs variety resulted from over-zealous polishing of a worn reverse die. The front foreleg was almost completely removed, and the back leg developed a "moth-eaten" appearance," said Ron Guth from PCGS.

「1937-D 3 腿品種是由於對磨損的反向模具過度拋光而產生的。前腿幾乎完全被去除，後腿出現了「蟲蛀」的外觀，」PCGS 的 Ron Guth 說。

Unfortunately, thousands of the coins entered circulation before the mistake was caught.

不幸的是，在錯誤被發現之前，已有數千枚硬幣進入流通。

"The 1937-D "three-legged" Buffalo nickel is one of the most famous and most important coins of the 20th century. It is arguably the classic Buffalo nickel," added David Hall, co-founder of PCGS.

「1937-D『三腳』水牛鎳幣是 20 世紀最著名、最重要的硬幣之一。它可以說是經典的水牛鎳幣，」PCGS 聯合創始人 David Hall 補充道。

Only 10,000 have survived to this day.

至今只有 1 萬人倖存。
