Why Are 1970s Coins So Valuable?

Many people ask, “Why are coins from just a few decades ago suddenly worth so much?” The answer boils down to three main factors: rarity, minting errors, and preservation.

During the 1970s, the U.S. Mint was transitioning through different production technologies and experimenting with new designs. These transitions sometimes resulted in unexpected minting errors, which were not always caught before the coins entered circulation. Today, those flaws make certain coins extremely rare and desirable.

Moreover, coins that have never been circulated—known as mint state (MS) or proof coins—retain their original shine, crisp details, and flawless surfaces. These are highly coveted by collectors. Coin grading services such as PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company) have become trusted authorities in assigning a numeric grade to coins, directly influencing their market value.

Collectors and investors value coins for their historical significance and long-term growth potential. Just like rare stamps or vintage sports cards, valuable coins appreciate over time, making them both a nostalgic and profitable hobby.

The 7 Most Valuable 1970s Coins

1. 1975 No S Proof Roosevelt Dime

• Estimated Value: $450,000 – $506,250
• What Makes It Valuable: Missing “S” mintmark
• Rarity: Only two known to exist

This dime is one of the rarest U.S. coins ever produced. All 1975 proof dimes were supposed to bear the “S” mintmark, indicating they were struck at the San Francisco Mint. But somehow, at least two dimes escaped the mint without the “S”, making them unicorns in the numismatic world. One of them sold for over half a million dollars (AP News).

2. 1970-S Small Date Lincoln Cent

• Estimated Value: Up to $18,400
• Identifying Feature: Small and high “7” in the date
• Tip: Compare with a large date version for clarity

This coin might appear normal at first glance, but a subtle variation in the size and alignment of the date makes all the difference. The small date version is far rarer than its large date counterpart. The “7” is higher than the other digits and the word “Liberty” often looks slightly blurry or less defined.

3. 1970-S Large Date Doubled Die Lincoln Cent (Proof)

• Estimated Value: Up to $24,150
• Key Feature: Doubled text on the obverse

This coin was the result of a die striking error, where the die used to stamp the coin was misaligned or re-punched, creating a doubled effect on text like “In God We Trust” or “Liberty.” In pristine proof condition, this doubled die coin can bring in tens of thousands.

4. 1971-S Doubled Die Obverse Lincoln Cent (Proof)

• Estimated Value: Up to $10,350
• Look For: Doubling in the words “Liberty” and “In God We Trust”

Another doubled die entry, this coin is highly valuable when the doubling is obvious and the coin is in deep cameo proof condition. The doubled design gives it a distinct appearance, and collectors are eager to get their hands on one in excellent shape.

5. 1971-S Deep Cameo Proof Penny

• Estimated Value: Up to $17,250
• Value Driver: Frosted design and mirror-like background

Deep Cameo proofs have sharp contrasts between the raised design and the flat background. This specific version from 1971 is rare in high grades, and its beauty contributes heavily to its value. It’s a collector’s dream for both its rarity and its visual appeal.

6. 1974-S Reverse Brockage of 1973-S Lincoln Cent

• Estimated Value: $11,400
• What to Look For: One side is a mirror image

This unusual coin occurred due to a minting mishap known as a “reverse brockage.” One coin got stuck in the minting press and imprinted itself onto the next blank planchet, creating a mirrored image on one side. It’s visually stunning and highly collectible.

7. 1979 Susan B. Anthony Dollar Over Jefferson Nickel

• Estimated Value: $15,275
• Minting Error: Struck over a nickel planchet

This coin is the result of a double-denomination error, which occurs when a coin design is struck onto a blank meant for another denomination. In this case, a Susan B. Anthony dollar was accidentally struck over a Jefferson nickel. It’s an incredibly rare mistake and has sold for more than $15,000.
