As a seasoned US coin collecting expert, I'm excited to delve into the fascinating world of 1970 pennies. While many may dismiss these common coins, there's more to them than meets the eye. Let's explore the hidden potential and surprising value of these small copper treasures.
Understanding the 1970 Penny
Before we dive into values, it's crucial to understand what makes the 1970 penny unique:
- Part of the Lincoln Memorial cent series (1959-2008)
- Obverse features Abraham Lincoln's profile
- Reverse displays the Lincoln Memorial
- Composition: 95% copper, 5% zinc
- Minted in Philadelphia, Denver, and San Francisco
Factors Influencing 1970 Penny Value
Several key elements determine a 1970 penny's worth:
- Mint mark
- Condition (grade)
- Variety (Small Date vs. Large Date)
- Errors or die varieties
- Copper melt value
Let's examine each factor in detail.

1970-S (San Francisco)
San Francisco pennies are more complex due to date size varieties:
1970-S Small Date

The Importance of Grading
Coin grading is paramount in determining a 1970 penny's value. The Sheldon Scale, ranging from 1 (poor) to 70 (perfect), is the industry standard. For 1970 pennies, key grades include:
- MS-63 to MS-65: Uncirculated with minor imperfections
- MS-66 to MS-67: Gem quality with few flaws
- MS-68 to MS-70: Nearly perfect to perfect (extremely rare for 1970 pennies)
Color designations for copper coins also affect value:
- RD (Red): Original mint luster
- RB (Red-Brown): Mixture of red and brown toning
- BN (Brown): Mostly brown due to circulation or toning
Red specimens typically command the highest premiums, especially in high grades.
Small Date vs. Large Date: A Crucial Distinction
The 1970-S pennies come in two varieties: Small Date and Large Date. Here's how to differentiate:
- Small Date: The 7 in 1970 is higher, aligning with the top of the 9
- Large Date: The 7 is lower, its top below the 9's top
The Small Date variety is generally more valuable, particularly in high grades or with certain errors.
Rare 1970 Penny Errors and Die Varieties
Errors and die varieties can significantly increase a 1970 penny's value. Notable examples include:
1970-S Doubled Die Obverse (DDO)
- FS-101 (Large Date): Most valuable 1970 penny error
- MS-65 RB value: Approximately $9,000
- MS-66 RD value: Up to $24,000
1970-S Proof LD/SD DDO (FS-102)
- Overdate error with Large Date over Small Date
- PR-66 RD value: Around $1,300
- PR-68 CAM value: About $1,500
1970-S Tripled Die Obverse (TDO)
- FS-107 (Large Date)
- PR-69 RD value: Approximately $1,140
Other Errors
- Off-center strikes: Value varies based on severity
- Double strikes: Can fetch $50-$200 depending on quality
- Wrong planchet errors (e.g., struck on dime planchet): Often worth $200+
The Copper Melt Value Factor
Even without errors or high grades, 1970 pennies have inherent value due to their copper content. As of 2023, the melt value fluctuates between $0.02 to $0.03, depending on current copper prices. However, it's crucial to note that melting US coins for their metal content is illegal.
How to Find Valuable 1970 Pennies
To increase your chances of discovering a valuable 1970 penny:
- Thoroughly examine change and penny jars
- Search through bank rolls (particularly for S-mint coins)
- Attend coin shows or visit reputable coin shops
- Seek out uncirculated rolls from 1970
- Use a high-quality magnifying glass (at least 5x) to spot errors and varieties
Preserving Your 1970 Penny's Value
If you believe you've found a valuable 1970 penny:
- Handle it by the edges, never touching the faces
- Store it in a non-PVC coin flip or holder
- Keep it in a cool, dry place away from direct sunlight
- For high-value coins, consider professional grading services like PCGS or NGC
Selling Your Valuable 1970 Penny
If you've identified a potentially valuable 1970 penny, consider these selling options:
- Online marketplaces (eBay, Heritage Auctions)
- Local coin shops (ensure they have a good reputation)
- Coin shows (great for networking with collectors)
- Numismatic associations (e.g., American Numismatic Association)
For high-value coins, obtain an appraisal from a reputable dealer or grading service before selling.
The 1970 Penny in Context: Historical and Numismatic Significance
To fully appreciate the 1970 penny, it's essential to understand its historical context:
- 1970 marked the end of an era for U.S. coinage, as it was the last year silver was used in circulating coins (40% silver Kennedy half dollars)
- The Vietnam War was ongoing, affecting the economy and metal prices
- The Apollo 13 mission captured the world's attention, highlighting America's technological prowess
From a numismatic perspective, 1970 pennies are significant because:
- They represent one of the last years of solid copper cents before the composition changed in 1982
- The San Francisco mint's production of both proofs and circulation strikes adds complexity to the series
- The Small Date/Large Date varieties provide an interesting study for collectors
Investment Potential of 1970 Pennies
While not typically considered investment-grade coins, certain 1970 pennies can offer solid returns:
- High-grade Red specimens have shown steady appreciation over time
- Rare errors, particularly the 1970-S DDO, have seen significant value increases
- The rising price of copper adds a "floor" to the value of even common specimens
However, as with any investment, past performance doesn't guarantee future results. Collectors should focus primarily on the historical and numismatic value of these coins.
Tips for Building a 1970 Penny Collection
For those interested in focusing on 1970 pennies, consider these collecting strategies:
- Start with the basics: Obtain examples from each mint (P, D, S)
- Pursue both Small Date and Large Date varieties for S-mint coins
- Focus on acquiring the highest grades within your budget
- Learn to identify common errors and varieties
- Consider collecting by die pair for advanced study
Conclusion: The Enduring Allure of the 1970 Penny
While most 1970 pennies are worth only a few cents, the potential for finding a rare and valuable coin makes them a perennial favorite among collectors. From pristine red uncirculated specimens to dramatic errors like the 1970-S DDO, these humble cents offer a world of possibilities for numismatists of all levels.
As you sift through your change or explore coin shops, remember that each 1970 penny tells a story—of American history, of numismatic evolution, and potentially of hidden treasure. Whether you're a seasoned collector or just starting out, the hunt for that special 1970 penny can be an exciting and rewarding journey.
Keep learning, keep searching, and may your coin collection grow in both value and personal significance. Happy collecting!
