Most pennies are worth just one cent—but one specific 1982 coin has collectors searching pocket change nationwide. The 1982-D Small Date 3.1 gram penny is a rare transitional variety that, in verified cases, can sell for thousands of dollars.
Here’s how to identify it, why it matters, and what it could be worth.
Why 1982 Was a Historic Year for U.S. Pennies
In 1982, the U.S. Mint changed the composition of the Lincoln cent due to rising copper prices.
The Big Change
- Before 1982: 95% copper (3.1 grams)
- After 1982: Zinc core with copper plating (2.5 grams)
During the transition, both copper and zinc pennies were struck—creating multiple varieties in the same year. That overlap is what makes certain 1982 coins valuable.
What Makes the 1982-D Small Date Special?
Among 1982 pennies, there are two date styles:
Small Date vs. Large Date
Small Date Features:
- Thinner, sharper numbers
- The “8” looks more compact
- The “2” has a smoother curve
- The “9” appears crisp and narrow
The rare version collectors want is:
1982-D + Small Date + 3.1 grams (copper)
This specific combination was not widely produced, making it extremely scarce.
The Critical Weight Test (3.1 Grams)
Weight is the most important factor in identification.
| Composition | Expected Weight |
|---|---|
| Copper | 3.1 grams |
| Zinc | 2.5 grams |
How to Weigh It
- Use a digital scale accurate to 0.1 grams
- Calibrate before use
- Place the coin flat and still
If your 1982-D Small Date penny weighs around 3.1 grams, you may have something special.
Why the Denver Mint Version Is Rare
The “D” mint mark under the date means the coin was struck at the Denver Mint.
Most 1982-D Small Date pennies were struck in zinc (2.5g). A confirmed copper (3.1g) Small Date from Denver is extremely rare.
That unexpected crossover—wrong metal for that date style—is what drives high value.
How Much Is It Worth?
Value depends on authenticity and condition.
Estimated Market Range (If Genuine)
- Circulated example: $5,000–$10,000+
- High-grade uncirculated: $15,000 or more at auction
Important: Only authenticated examples carry these values.
Authentication Is Essential
Because of its potential value, professional grading is critical.
Major services include:
- Professional Coin Grading Service (PCGS)
- Numismatic Guaranty Company (NGC)
Certification confirms:
- Date style
- Metal composition
- Weight
- Authenticity
- Condition grade
Without professional verification, buyers may be hesitant.
Common Mistakes to Avoid
Many collectors misidentify common coins as rare. Avoid these errors:
- Mistaking Large Date for Small Date
- Using inaccurate scales
- Ignoring mint mark details
- Cleaning the coin (reduces value dramatically)
- Assuming all 3.1g pennies are rare
Always compare with verified reference images.

Why Transitional Coins Attract Collectors

Owning a rare transitional piece means holding a coin tied directly to economic change and Mint decision-making.
FAQs About the 1982-D Small Date Penny

No. Most are common zinc coins worth one cent.
2. How do I tell Small Date from Large Date?
Look at the shape of the numbers—Small Date digits are thinner and more compact.
3. What scale should I use?
Use a calibrated digital scale that measures to at least 0.1 grams.
