Ever wondered if the loose change in your drawer could be a mini treasure chest? Some coins from the 1970s are worth way more than face value—some even fetch over $10,000. The key? Minting errors, rare variations, and collector demand. Whether you’re just curious or already a coin lover, here’s your detailed guide to five valuable 1970s coins, how to spot them, and what makes them worth serious money.
Value
Coin collecting is more than a hobby—it’s part history, part detective work, and part investment. During the 1970s, rapid advances in minting tech and design updates led to a few interesting mistakes. Those errors turned ordinary coins into prized collectibles. Condition and rarity play a big role in value, which is why expert grading services like PCGS and NGC are key in verifying these coins.
Here’s a breakdown of five rare coins from the 1970s that could be sitting in your pocket or coin jar.
1971‑S Lincoln Cent (Double Die Obverse)
This coin has a double image on the front, caused by the die striking the coin twice by mistake.
How to spot it:
- Use a magnifying glass to examine “LIBERTY” and the date.
- Look for clear, overlapping lines or shadow-like effects.
- Compare it with a standard 1971‑S penny using trusted sources like NGC.
What it’s worth:
In top condition, these coins can sell for over $10,000 at auction.
1974‑S Lincoln Cent (Brockage Error)
Brockage errors happen when one coin sticks to the die and causes a reverse, mirror image on the next coin struck.
How to identify it:
- Look for reversed or distorted imagery on one side.
- These often look like a “ghost” image on the reverse.
- Use reference guides from ANA or PCGS.
Estimated value:
Depending on condition, these rare errors can bring in five figures.
1979 Susan B. Anthony Dollar (Overstruck on 1978 Nickel)
It’s a double-design coin—the result of a 1979 Susan B. Anthony dollar being struck on top of a 1978 Jefferson nickel.
Spotting tips:
- Look for traces of both designs.
- You might see Jefferson’s head alongside the Susan B. Anthony design.
- This type of error is extremely rare, so expert verification is key.
Potential payout:
These overstrike errors can fetch more than $10,000 due to their uniqueness.
1971‑S Deep Cameo Proof Penny
This isn’t an error—it’s a high-quality proof coin with a deep cameo finish (frosted design, shiny background).
How to recognize it:
- Look for mirror-like shine and sharp contrast.
- Deep cameo proofs have a frosted Lincoln and glossy backdrop.
- Check the sharpness in Lincoln’s features—proofs are extra detailed.
What it’s worth:
In mint condition, this coin can be worth well over $10,000, especially when slabbed by PCGS or NGC.
1970‑S Lincoln Cent (Small Date Variation)
This variation has a smaller and slightly higher “7” in the date compared to the large date version.
How to identify:
- Use a magnifier to inspect the size and position of the “7”.
- Compare side-by-side with a large date version.
- Consult PCGS photo guides for a visual match.
Market value:
Even minor visual changes like this can mean a big payday—well over $10,000 for uncirculated versions.
