5 Most Valuable 1970s Coins Worth $10,000+ and How to Identify Them

Introduction

The 1970s were a transformative time for America: political upheaval, economic shifts, and cultural revolutions. While bell bottoms and disco balls defined the fashion and music of the decade, the coins minted during these years hold secrets that go far beyond their face value. For numismatists and savvy collectors, several 1970s-era coins have surfaced in recent years, fetching astounding figures—sometimes over $10,000—at auctions and private sales.

Why? In a nutshell: minting errors, low mintage numbers, and historical quirks have all played a role in making certain 1970s coins exceptionally rare and valuable.

In this article, we’ll explore five specific coins from the 1970s that have fetched prices over $10,000 due to their rarity and collectibility. We’ll dive into what makes them special, how to identify them, and why collectors are willing to pay a fortune for them. If you’re sitting on old change or have inherited a coin collection, this guide might just help you spot a hidden gem.

1. 1970-S Small Date Lincoln Cent (Doubled Die Obverse)

Estimated Value: $10,000–$24,000+

Overview:

Among the rarest and most sought-after pennies ever produced in the United States, the 1970-S Small Date Lincoln Cent with Doubled Die Obverse is a marvel of minting anomalies. Most 1970 pennies aren’t worth more than a few cents—except this one.

What Makes It Rare:

There are two main factors that make this coin valuable:

• Small Date Variety: The “7” in the date appears level with the other numbers, unlike the more common “Large Date” variety.
• Doubled Die Obverse (DDO): This specific coin was struck with a die that accidentally doubled the design, causing certain elements (especially “LIBERTY” and the date) to appear with visible doubling.

Where to Look:

Check Lincoln Cents from 1970, especially those minted in San Francisco (denoted by an “S” under the date). Examine the date and the word “LIBERTY” under a magnifying glass or microscope.

Auction History:

• A MS-64 RD (Mint State, Red) example sold at Heritage Auctions for $24,150.
• Circulated versions still fetch thousands.

2. 1975 No “S” Proof Roosevelt Dime

Estimated Value: $350,000+

Overview:

This coin is a Holy Grail among modern dimes. Only two known examples exist, making it not just rare—but ultra rare.

What Makes It Rare:

• Intended only for proof sets, this coin lacks the expected “S” mintmark, indicating it was accidentally struck without the San Francisco Mint’s identifier.
• Proof coins are struck using specially polished dies for collectors, and errors like this are essentially not supposed to happen.

How to Spot It:

• Only proof sets from 1975 might contain this error. Look for dimes with mirror-like surfaces that lack the “S” mintmark.
• Regular business-strike dimes (the kind you’d find in pocket change) aren’t the same; this coin is exclusively found in proof sets.

Auction History:

• One sold for $349,600 in 2019.
• Considered one of the most valuable U.S. dimes ever sold.

3. 1976-S Bicentennial Silver Proof Quarter (Type 2)

Estimated Value: $10,000+ (in ultra high grade)

Overview:

To commemorate America’s 200th birthday, the U.S. Mint released special Bicentennial coins in 1975 and 1976, all bearing the dual date “1776–1976.” Among these is a proof quarter struck in 40% silver, only available in certain collector sets.

What Makes It Rare:

• Type 2 Proofs have sharper details and clearer lettering, especially in the word “AMERICA” on the reverse.
• Many proof sets were mishandled or degraded over time, making PR70 (Perfect Proof) examples extremely rare and valuable.

How to Identify:

• Look for the “S” mintmark (San Francisco).
• The reverse design features a Colonial Drummer, unique to the Bicentennial quarter.
• Type 2 versions have crisp, narrow lettering.

Auction History:

• High-grade examples in PR70 Deep Cameo (DCAM) have sold for over $10,000 at auction.

4. 1971 Eisenhower Dollar – Friendly Eagle Variety

Estimated Value: $10,000–$15,000 (MS66 and higher)

Overview:

The Eisenhower Dollar (1971–1978) was America’s last large-sized dollar coin minted for circulation. Most aren’t worth much, but the 1971 “Friendly Eagle” variety stands apart.

What Makes It Rare:

• On the reverse, the eagle clutching an olive branch is less detailed and more “friendly” looking due to a die modification.
• Scarcity in higher grades like MS66+ dramatically increases value.

How to Identify:

• The “Friendly Eagle” appears on 1971 coins without a mintmark (Philadelphia mint).
• The eagle’s eye is missing, the beak is softened, and the Earth below is less defined.

Auction History:

• A certified MS66 “Friendly Eagle” dollar sold for over $10,000.
• Only a handful of high-grade examples are known to exist.

5. 1974-D Aluminum Lincoln Cent (Pattern Coin)

Estimated Value: $250,000+ (if legally owned)

Overview:

In 1974, the U.S. Mint experimented with making pennies out of aluminum due to rising copper prices. Roughly 1.5 million were struck but never released to the public—and nearly all were destroyed.

What Makes It Rare:

• Only a few escaped destruction.
• The coin never entered circulation, making it a “pattern coin”, which is often extremely collectible if legally owned.

Controversy:

• Many known examples were recalled and destroyed by the Mint.
• Ownership legality is debated; a few specimens have surfaced at auction, but have also been pulled due to legal uncertainty.

Auction History:

• In 2014, one example was estimated to fetch $250,000, but legal challenges by the U.S. Mint prevented the sale.

Conclusion

Coins from the 1970s are often dismissed as modern, plentiful, and valueless. But hidden among the ordinary cents, dimes, quarters, and dollars are some extraordinary treasures worth small fortunes. Whether it’s a doubled die, a missing mintmark, or a rare composition, these anomalies have turned pocket change into auction gold.

If you’re a collector—or even just someone with a jar full of old coins—it’s worth your time to look closely. Sometimes, numismatic history and financial gain go hand-in-hand, and the key to both could be sitting unnoticed in your home.

So next time you’re sorting through your change, keep an eye out. Because the 1970s weren’t just a time of change in society—they were also a time of valuable change in your pocket.
