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

The 1970-S Small Date Lincoln Cent is one of the rarest varieties of the Lincoln penny series. While most 1970-S pennies are common, the Small Date version with a Doubled Die Obverse is a collector’s gem.

How to Identify:

• Look for a small date, where the “9” is pointed and curves upward slightly.
• The word “LIBERTY” appears less defined and somewhat faint.
• A clear doubling effect is visible on “IN GOD WE TRUST.”

Value:

In uncirculated condition, this coin has sold for as much as $18,400 at auction.

Tip: Check your 1970-S pennies with a magnifying glass to spot the Small Date variety and potential doubling.

2. 1975 No S Proof Dime

One of the rarest and most valuable dimes, the 1975 No S Proof Dime is a coin collector’s dream. It was minted in a proof set, but due to an error at the San Francisco Mint, it lacks the “S” mint mark.

How to Identify:

• It is only found in proof sets, meaning it has a mirror-like finish.
• The coin lacks an “S” mint mark above the date.

Value:

With only two known specimens, one was auctioned for $506,250.

Tip: If you have a 1975 proof set, inspect the dime for a missing mint mark—it could be worth a fortune!

3. 1972 Lincoln Cent (Doubled Die Obverse)

The 1972 Lincoln Cent with a Doubled Die Obverse is another valuable find, thanks to a striking error that caused the coin’s inscriptions to appear doubled.

How to Identify:

• The words “IN GOD WE TRUST,” “LIBERTY,” and the date (1972) show clear doubling.
• The doubling is strongest and easiest to see on the date.

Value:

• Lower-grade examples sell for $400.
• High-grade uncirculated versions can fetch thousands of dollars.

Tip: This coin is relatively common among doubled die varieties, so look carefully!

4. 1974 Aluminum Cent

The 1974 Aluminum Cent is one of the most mysterious U.S. coins ever produced. The U.S. Mint experimented with aluminum cents due to the rising cost of copper, but the coins were never released into circulation. Only a few escaped, making them incredibly rare.

How to Identify:

• It is much lighter than a regular penny.
• The coin has a silver-gray appearance instead of the usual copper color.
• It is not magnetic (unlike steel coins).

Value:

A 1974-D aluminum cent was discovered in 2014, estimated to be worth between $250,000 and $2 million.

Tip: If you come across a very light penny, have it professionally authenticated!

How to Identify:

• There are no visible islands near Florida.

Value:

High-grade versions of this coin have sold for up to $1,000.

Tip: Many collectors overlook Eisenhower dollars, so check your 1972 coins carefully!
