带帽的左四分之一鹰：直径减小和有趣的历史

左帽头缩小直径四分之一鹰金币是美国造币厂于 1829 年至 1834 年间铸造的金币，是一种稀有面额，发行量较低，从未超过 4,600 枚。威廉·尼斯 (William Kneass) 对罗伯特·斯科特 (Robert Scot) 原始设计的修改包括减少字母、星星和日期，同时保持正面和背面分别为自由女神和鹰的整体拟人化。 1829 年引入的领模提高了硬币的均匀度并增加了边缘的筘边。尽管有较高的边缘保护设计，但硬币的高含金量导致硬币被广泛熔化以获取利润，特别是 1834 年发行的硬币。商业罢工很少见，会带来高额溢价，而证明的例子则极其罕见且昂贵。

Mintage Details of the Capped Head Left Quarter Eagle, Reduced Diameter

带帽的左四分之一鹰铸币细节，直径缩小

Introduction

介绍

The quarter eagle was an authorized gold coin denomination, but production was limited in the late 1820s and early 1830s. Mintage levels remained relatively constant for the Capped Head Left, Reduced Diameter type issued from 1829 to 1834, with the highest number of coins produced in any year being 4,600.

25 美分鹰是一种授权金币面额，但在 1820 年代末和 1830 年代初产量有限。 1829 年至 1834 年间发行的左帽缩径型硬币的发行量保持相对稳定，任何年份的最高产量为 4,600 枚。

Challenging Conditions

具有挑战性的条件

Gold coins were not widely circulated during this period. Those that were commanded a premium, as their gold content exceeded their face value. To conserve the nation's gold reserves, Congress suspended production of the $10 eagle in 1804, placing the responsibility of international exchange on the half eagle.

这一时期的金币并没有广泛流通。那些被要求溢价的东西，因为它们的含金量超过了它们的面值。为了保存国家的黄金储备，国会于 1804 年暂停了 10 美元鹰金币的生产，将国际兑换的责任交给了半鹰金币。

Engraver William Kneass's Enhancements

雕刻师 William Kneass 的增强功能

Upon the passing of Chief Engraver Robert Scot in 1823, William Kneass was hired to refine existing coin designs. While maintaining the essence of Scot's Capped Head Quarter Eagle design, Kneass made subtle adjustments, including reducing the size of letters, stars, and date punches.

1823 年，首席雕刻师罗伯特·斯科特 (Robert Scot) 去世后，威廉·克尼斯 (William Kneass) 受聘完善现有的硬币设计。在保留 Scot's Capped Head Quarter Eagle 设计精髓的同时，Kneass 进行了微妙的调整，包括减小字母、星星和日期打孔的大小。

Technological Advancement: The Collar Die

技术进步：衣领模具

The most significant change introduced by Kneass was technical in nature: the implementation of the collar die in 1828. This device not only inscribed reeding on the edge of the coin but also ensured uniformity in diameter by preventing excessive metal expansion during striking. The higher rim created by the collar die also protected the surface designs.

Kneass 引入的最重大的变革是技术性的：1828 年采用了领模。该装置不仅在硬币边缘刻有簧片，而且通过防止冲压过程中金属过度膨胀来确保直径的均匀性。领模形成的较高边缘也保护了表面设计。

Meltdown and Reduced Weight

熔毁和重量减轻

The high price of gold incentivized individuals to melt down coins for profit, particularly during the final year of issue (1834). To discourage this practice, Congress reduced the weight of the quarter eagle in 1834, ensuring that its bullion value remained below its face value. While most of the heavier-weight 1834 coins were melted after the new law took effect, some believe that surviving examples may be Proofs.

金价高涨刺激个人熔铸硬币以获取利润，特别是在发行的最后一年（1834 年）。为了阻止这种做法，国会于 1834 年减轻了四分之一鹰的重量，确保其金条价值低于其面值。虽然大部分较重的 1834 年硬币在新法律生效后都被熔化，但一些人认为幸存的硬币可能是精制币。

Rarity and Value

稀有性和价值

Capped Head Left Quarter Eagles in business strike condition are scarce to rare, with population totals for any given year not exceeding 150 coins. Prooflike specimens have been certified for half of the dates. Select Uncirculated (MS62) and finer coins are highly valued. The classic 1834 rarity is exceptionally expensive, while Gem and finer coins of other dates command higher prices. Proofs, with no more than 10 known for any date, are very expensive to extremely expensive.

处于商业罢工状态的头顶左四分之一鹰非常罕见，任何一年的数量总数都不超过 150 个硬币。样样样本已获得一半日期的认证。选择未流通（MS62）和更精美的硬币价值更高。经典的 1834 年稀有硬币异常昂贵，而宝石和其他日期的更精美硬币的价格更高。任何日期已知​​的证明都不超过 10 个，其成本非常昂贵甚至极其昂贵。
