Most pennies are worth just one cent. But one extraordinary 1982-D Small Date Copper Lincoln penny shocked collectors when it sold for an incredible $398,000 at auction. Even more surprising, experts say this coin is rarer than the famous 1943 copper penny.
This guide explains everything step-by-step so you can understand why it’s valuable — and how to check if you might own one. 👇
📖 Step 1: Why the Year 1982 Is So Important
The year 1982 marked a major transition in U.S. penny production. The mint changed the metal composition to reduce costs.
Here’s what happened:
- 🔶 Before mid-1982: Pennies were made of 95% copper
- 🔶 After mid-1982: Pennies switched to copper-plated zinc
- ⚖️ Copper pennies weigh about 3.11 grams
- ⚖️ Zinc pennies weigh about 2.5 grams
During this transition at the Denver Mint, a small number of leftover copper blanks were accidentally used with the Small Date design, creating one of the rarest modern coin errors ever discovered.
💎 Step 2: What Makes This Penny Extremely Rare
This coin is considered one of the most important Lincoln penny varieties ever found.
Here’s why collectors value it so highly:
- ✅ Only 3 confirmed examples exist worldwide
- ✅ It combines three rare features:
- Small Date design
- Denver “D” mintmark
- Copper composition
- ✅ All known examples are in Mint State condition
Because of this extremely low population, collectors consider it a true modern treasure.

You can check your penny using these simple tests:
