1913 Liberty Head Nickel | Only 5 known to exist | $3.7 million | Look for the 1913 date on Liberty Head nickels. |
1943 Copper Penny | Accidentally minted in copper instead of steel | $200,000+ | Use a magnet—copper pennies will not stick. |

1. The $1.5 Million Roosevelt Dime – Why Is It So Valuable?
The 1975 no-S Roosevelt dime was one of a proof set minted by the San Francisco Mint, usually featuring an “S” mintmark. Unfortunately, a small batch of dimes were erroneously struck without the mint mark and circulated. One of them was sold for a record amount of $1.5 million.

How to Identify This Coin:
- Date: 1975
- Mintmark: Must lack the “S” proof mintmark on proof dimes.
- Appearance: Mirror finish on proof coins.
- Where to Find: Frequently discovered in 1975 proof coin sets.
Tip: If you own a 1975 proof set, examine the dime under magnification to look for the missing mintmark.
2. The 1913 Liberty Head Nickel – A $3.7 Million Rarity
The 1913 Liberty Head Nickel is a globally renowned coin. There are just five specimens of this coin in existence; hence, it’s considered a mythical piece to collect. One specimen auctioned for $3.7 million.
How to Identify This Coin:
- Date: 1913
- Obverse: Lady Liberty facing left inscribed as “LIBERTY.”
- Reverse: A Roman numeral “V” representing five cents.
- Weight: Around 5 grams.
Tip: Authenticating a 1913 nickel is done with expert confirmation since it’s been counterfeited many times.
3. The 1943 Copper Penny – A World War II Error Worth $200,000+
In 1943, the U.S. Mint made the wartime switch from copper to steel for pennies to save metal. But a few pennies of copper were inadvertently struck, which makes them very valuable.
How to Identify This Coin:
- Date: 1943
- Material: Copper (try using a magnet; copper pennies won’t stick).
- Weight: 3.11 grams (normal copper penny weight).
- Color: Brownish instead of the typical silvery 1943 steel pennies.
Tip: Be careful of manipulated steel pennies that are copper-plated to look like the rare copper version.
4. The 1955 Doubled Die Penny – A Collectible Error Worth $40,000+
The 1955 Doubled Die Lincoln Penny is one of the most famous mint errors in U.S. history, notable for its boldly doubled obverse inscriptions.
How to Identify This Coin:
- Date: 1955
- Doubling Effect: Distinct doubling on the words “LIBERTY” and “IN GOD WE TRUST.”
- Mintmark: No mintmark (Philadelphia strike).
Tip: Genuine specimens exhibit good doubling and must not have a doubled mintmark.
5. The 2004 Wisconsin Quarter – The Extra Leaf Mystery
In 2004, a few Wisconsin state quarters were minted with an additional leaf on the corn stalk design on the back. This minting flaw makes them a valuable collector’s item.

How to Identify This Coin:
- Date: 2004
- Design Error: Be on the lookout for a high or low leaf to the left of the corn stalk.
- Mintmark: “D” for Denver.
Tip: Be sure to inspect your loose change because these quarters remain in circulation.
6. The 1969-S Doubled Die Penny – A $35,000 Error
The 1969-S Doubled Die Penny is yet another extremely valuable coin because of its prominent doubling mistake.
How to Identify This Coin:
- Date: 1969
- Mintmark: “S” below the date.
- Doubling: Date and inscriptions are distinctly doubled.
Tip: Make sure that the mintmark is not doubled, as legitimate errors only show on the principal inscriptions.
