探索林肯美分误差的迷人世界，重点关注有趣的“轧机”误差和一些 1952 年版美分上发现的奇特的凹凸脊线。

Ever stumble upon a Lincoln Cent that looks a little…off? Well, you might have found yourself a rolling mill error! Let's dive into the weird world of 'Lincoln Cent, Rolling Mill, Error' and explore those odd lumpy ridges that pop up, especially on some 1952-D pennies.

有没有偶然发现过看起来有点……不对劲的林肯美分硬币？好吧，您可能发现自己犯了轧机错误！让我们深入了解“林肯美分硬币、轧机、错误”的怪异世界，探索那些突然出现的奇怪的凹凸脊线，尤其是在一些 1952 年版便士上。

The Case of the Lumpy 1952-D Lincoln Cents

1952-D 块状林肯美分案例

Back in February 2022, coin collectors were buzzing about a 1952-D Lincoln Cent with a strange texture. This wasn't your run-of-the-mill imperfection; this cent had lumpy, parallel ridges on the unstruck part of its face. Then, another one surfaced, and then another! What was going on?

早在 2022 年 2 月，硬币收藏家就对质地奇怪的 1952 年版林肯美分硬币议论纷纷。这并不是你一般的缺陷；而是你的缺陷。这枚硬币在其表面未受到撞击的部分上有凹凸不平的平行脊线。然后，又一个出现了，然后又一个！发生了什么事？

Ruling Out the Usual Suspects

排除通常的嫌疑

At first, folks thought it might be a lamination error, but no cracking was found. A split planchet? Nope, the weight was right. Some even considered crushed split blanks, but that seemed unlikely to only affect 1952-D cents. The idea of a metal flake during the rolling process was also floated, but the weight issue threw a wrench in that theory too.

起初，人们认为这可能是层压错误，但没有发现裂缝。分割板？不，重量是对的。有些人甚至考虑压碎裂片，但这似乎不太可能只影响 1952-D 美分。在轧制过程中使用金属薄片的想法也被提出，但重量问题也对该理论产生了影响。

The Occluded Gas Bubble Theory…Busted!

闭塞气泡理论……破灭了！

Someone suggested occluded gas bubbles – gas expanding under the surface, pushing up the metal. But these ridges were solid, not flexible. Plus, gas bubbles usually show up on the struck part of the coin, and these cents were lump-free in those areas. And to top it off, the coin rang like a normal cent when dropped. No dull thud here!

有人提出闭塞气泡——气体在表面下膨胀，向上推金属。但这些山脊是坚固的，不灵活。另外，气泡通常会出现在硬币的压印部分，而这些美分在这些区域没有肿块。最重要的是，硬币掉落时发出的声音就像正常的美分一样。这里没有沉闷的撞击声！

Rolling Mill Damage: The Prime Suspect

轧机损坏：头号嫌疑人

So, what's the most plausible explanation? The rollers themselves! The theory is that damaged or defective rollers, with irregular grooves and pits, transferred these imperfections to the cent strip. Those grooves and pits then show up as elongated, lumpy ridges on the coins. The ripples parallel to the ridges on one specimen really support this idea. The rollers might have been made from poor quality steel. Over time, they could have experienced wear, leading to those funky grooves and pits.

那么，最合理的解释是什么？滚筒本身！其理论是，带有不规则凹槽和凹坑的损坏或有缺陷的滚筒将这些缺陷转移到分条上。这些凹槽和凹坑随后在硬币上表现为细长的、凹凸不平的脊。一个标本上与脊平行的波纹确实支持了这一想法。滚轮可能是由劣质钢制成的。随着时间的推移，它们可能会经历磨损，导致出现那些奇怪的凹槽和凹坑。

What Does this Mean for Your Coin Jar?

这对您的硬币罐意味着什么？

The bottom line? If you find a 1952-D Lincoln Cent with weird, lumpy ridges, especially on the unstruck part, you might have a cool rolling mill error on your hands! While this specific error seems tied to a batch of 1952-D cents, it highlights the potential for all sorts of errors to occur during the minting process.

底线是什么？如果您发现一枚 1952 年 D 版林肯美分硬币有奇怪的、凹凸不平的脊线，尤其是在未敲击的部分，那么您可能遇到了很酷的轧机错误！虽然这个特定错误似乎与一批 1952-D 美分有关，但它凸显了在铸造过程中发生各种错误的可能性。

On a completely unrelated note, a recent incident where Paxos accidentally minted $300 trillion PYUSD highlights the transparency blockchain offers. While a massive error, it was quickly identified and corrected, showcasing blockchain's potential for financial oversight. Now, back to those pennies!

另一个完全不相关的事实是，最近 Paxos 意外铸造了 300 万亿美元 PYUSD 的事件凸显了区块链提供的透明度。虽然这是一个巨大的错误，但它很快就被识别并纠正，展示了区块链在金融监管方面的潜力。现在，回到那些便士！

So, keep your eyes peeled, folks! You never know what treasures (or errors) you might find hiding in plain sight. Happy collecting!

所以，各位，请擦亮眼睛！您永远不知道您可能会发现隐藏在众目睽睽之下的宝藏（或错误）。收藏愉快！
