水牛镍币非常受欢迎，但一个小细节就能区分价值几百美元和超过 10 万美元的镍币

这些稀有的镍币是美国于 1913 年至 1938 年间铸造的。由于硬币的正面有美洲原住民的头像，因此有时也被称为印第安头像镍币。硬币的背面有一头水牛。

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.

模具断裂，也称为反刍，是当模具（用于撞击硬币的金属片）在边缘附近缺少一块时形成的硬币上的错误。

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.

当模具撞击硬币时，它们会产生很大的冲击力和压力，并且硬币空白部分（称为毛坯）的金属与模具缺失部分留下的区域重叠。

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

由于美国造币厂严格的质量控制措施，出现这种畸形的硬币很少见。

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

当此类错误确实发生时，它们通常会被捕获并销毁。

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

然而，那些漏网之物却成为了巨大的收藏品，其价值远高于其面值。

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

丹佛铸币厂的一次失误导致铸造了数千枚镍币，而水牛也失去了一条腿。

"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 腿品种是由于对磨损的反向模具过度抛光而产生的。前腿几乎完全被去除，后腿出现了“虫蛀”的外观，”PCGS 的 Ron Guth 说。

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

不幸的是，在错误被发现之前，已有数千枚硬币进入流通。

"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“三足”水牛镍币是 20 世纪最著名、最重要的硬币之一。它可以说是经典的水牛镍币，”PCGS 联合创始人 David Hall 补充道。

Only 10,000 have survived to this day.

至今只有 10,000 人幸存。
