1970-S Lincoln Cent
One of the most famous mint errors of the 1970s, the 1970-S Lincoln Cent features a doubled die obverse, where elements like the word “LIBERTY” and the date appear duplicated.
- This error happened when the die struck the coin multiple times at slightly different angles.
- Collectors love this coin for its distinct appearance and rarity.
- A well-preserved example has sold for over $24,000 at auction.
1971-S Lincoln Cent
Similar to the 1970-S Lincoln Cent, the 1971-S Lincoln Cent also features a doubled die obverse. However, this variety is even rarer, making it highly sought after.
- The doubling is most visible on the date and inscriptions.
- Due to its scarcity, collectors are willing to pay over $10,000 for a well-preserved coin.
1974-S Lincoln Cent
In the early 1970s, the U.S. Mint experimented with aluminum pennies to reduce rising metal costs. The 1974-S Aluminum Lincoln Cent was one of these test coins.
- Most of these aluminum pennies were destroyed, making surviving examples extremely rare.
- When they appear at auctions, they often sell for $15,000 or more.
- If a flawless specimen were ever discovered, it could be worth even more.
1976 Bicentennial Quarter
To celebrate America’s 200th birthday, the 1976 Bicentennial Quarter was minted with a unique colonial drummer design.
- While most were circulated, a select few were struck in silver as proofs.
- Silver proof versions with a deep cameo contrast (frosted design on a mirror-like background) are especially valuable.
- High-grade versions can sell for $15,000 or more.
1970-S Proof Half Dollar
Mint marks indicate where a coin was produced, but some 1970-S Proof Half Dollars were mistakenly struck without the “S” mint mark.
- This error is incredibly rare, with fewer than 50 known examples.
- Coins in top condition have sold for $15,000 to over $30,000 at auctions.
1975 Roosevelt Dime
The 1975 Roosevelt Dime struck on a penny planchet is a fascinating minting error.
- This happened when a blank penny planchet accidentally entered the dime press, producing a dime design on a penny-sized blank.
- Due to its rarity, these error coins have sold for over $15,000, especially in high grades.
1979-S Susan B. Anthony Dollar
The 1979-S Susan B. Anthony Dollar was the first small-sized U.S. dollar coin. However, there were two distinct proof varieties—Type I and Type II.
- The Type II proof features a sharper, clearer “S” mint mark, making it rarer.
- These coins are highly sought after, with high-grade examples selling for $15,000 or more.
