Most pennies are worth exactly one cent — but the 1982-D Small Date Copper Lincoln Cent is one of the most extreme exceptions in U.S. coin history.
With a confirmed auction sale of $398,000, this coin is considered the holy grail of modern Lincoln cents, and numismatic experts agree it is rarer than the famous 1943 copper penny.
Let’s break down why this coin exists, how to identify one, and what to do if you think you’ve found it.
🪙 Step 1: The 1982 Penny Transition — Why This Error Exists
The year 1982 was a turning point for U.S. coinage.
- 🔸 Before mid-1982: Pennies were struck in 95% copper
⚖️ Weight: ~3.11 grams - 🔸 After mid-1982: The Mint switched to copper-plated zinc
⚖️ Weight: ~2.50 grams
During this transition, the Denver Mint accidentally struck a Small Date design on leftover copper planchets — creating a coin that was never meant to exist.
💡 This combination should be impossible:
Small Date + “D” Mintmark + Copper Composition
🔥 Step 2: Why It’s Rarer Than the 1943 Copper Penny
The rarity of this coin is what makes it legendary:
✔ Only three confirmed examples worldwide
✔ Fewer than the known 1943 copper cents
✔ All examples are Mint State
✔ No circulation finds since 2009
📌 Many experts consider this the rarest Lincoln cent variety ever authenticated.
🔍 Step 3: How to Identify a Genuine 1982-D Small Date Copper Penny
Use this comparison chart to rule out common zinc cents:
| Feature | Rare 1982-D Copper (Small Date) | Regular 1982-D Zinc |
|---|---|---|
| Weight ⚖️ | 3.11 g ± 0.05 | ~2.50 g |
| Date Style | Straight-base “2” (Small Date) | Curved “2” (Large Date) |
| Mintmark | “D” below date | “D” below date |
| Edge | Solid copper color | Zinc core visible |
| Sound Test | Sharp ringing tone | Dull “clink” |
📌 Pro Tip:
Use a digital scale (0.01 g accuracy) and a 10× loupe for fast screening.
💵 Step 4: Auction History & Value Growth
Only three certified coins are known:
- MS65BN (PCGS) → Private Collection
- MS64RD (NGC) → Smithsonian Institution
- MS63RB (ANACS) → Legend Numismatics
📈 Market Performance
| Year | Approximate Value |
|---|---|
| 2010 | $112,500 |
| 2017 | $398,000 |
| 2030 (Projected) | $750,000+ |
💡 Values have more than tripled in just over a decade.
🏦 Step 5: Where More Examples Could Be Hiding
Experts believe 5–10 coins may still exist. The best places to search:
- 🏦 Original 1982-D bank rolls
- 💰 Old $50 penny bags from vault storage
- 📦 Estate collections formed in the early 1980s
🪙 Last confirmed discovery: Minnesota bank roll, 2009.
✅ Step 6: Authentication Checklist (Critical)
Before submitting for grading, confirm all of the following:
✔ Weight reads 3.11 g
✔ Small Date numerals (straight-base “2”)
✔ Solid copper edge (no zinc core)
✔ XRF test confirms 95% copper
✔ Submission to PCGS or NGC only
🚫 Red Flags
- Weight under 3.05 g
- Plated zinc coins
- Altered or added “D” mintmark

The 1982-D Small Date Copper Cent is considered a blue-chip rarity in U.S. numismatics.
