1. 1913 Liberty Head Nickel – A $86 Million Treasure

Rarity Meets Historical Mystery

• Mintage: Only 5 known to exist
• Estimated Value: $75–$86 million
• Key Features: Liberty Head design, no mint mark, date “1913”

This nickel was never officially authorized for production. The five specimens were struck under mysterious circumstances, possibly at the Philadelphia Mint. One famously appeared in a 1970s episode of Hawaii Five-O, adding to its legendary status.

Authentication Tips

• Slightly raised date with curved “3”
• Weight: 5 grams
• Composition: 75% copper, 25% nickel

2. 1943 Bronze Lincoln Penny – Mistaken Metal Worth Millions

A Wartime Error Turned Goldmine

• Mintage: Approximately 15 known
• Estimated Value: $500,000 to $3 million+
• Key Features: 1943 date, bronze color, not magnetic

During WWII, copper was needed for military equipment, so steel was used for pennies. However, a few bronze planchets from 1942 were accidentally used in 1943. These rare coins fetch top dollar at auctions.

Identification Guide

• Weight: 3.11 grams (steel versions weigh 2.7g)
• Non-magnetic
• Rich brown or reddish tone

3. 2004-D Wisconsin Extra Leaf Quarter – An Agricultural Error

A Modern Marvel with a Mint Mistake

• Mintage: Unknown, but limited
• Estimated Value: $500–$6,000
• Key Features: Extra “leaf” on the ear of corn (high or low variety)

This coin stands out for an extra design element that wasn’t meant to be there. These were struck in Denver and slipped into circulation, making them extremely collectible.

Diagnostic Clues

• Look for an additional leaf—either pointing up or drooping low
• Mint mark “D” for Denver

4. 1970-S Small Date Lincoln Penny (Overstruck on 1941 Canadian Cent)

A Coin-Within-A-Coin Phenomenon

• Mintage: Extremely rare
• Estimated Value: $35,000–$100,000+
• Key Features: “S” mint mark, faint image of Canadian cent under design

An unusual error where a 1941 Canadian cent planchet was reused to strike a 1970-S penny. Visible remnants of both coins make it a numismatic marvel.

Identification Tips

• Look for doubling or ghostly outline behind Lincoln’s image
• Use magnification to confirm dual date impressions

5. 1955 Doubled Die Lincoln Cent – A Collector Favorite

Double Vision That Pays Off

• Mintage: Estimated 20,000–24,000
• Estimated Value: $1,000–$20,000+
• Key Features: Extreme doubling on “LIBERTY” and “IN GOD WE TRUST”

This dramatic doubling happened due to a misalignment during the die hubbing process. The result is unmistakable and highly sought after.

Visual Checklist

• Strong doubling on obverse lettering
• No doubling on reverse (to avoid confusion with machine doubling)

6. 2005 “In God We Rust” Kansas Quarter – A Defective Die Pays Dividends

A Missing Letter That Adds Value

• Mintage: Unknown error run
• Estimated Value: $100–$1,500
• Key Features: “IN GOD WE TRUST” appears as “IN GOD WE RUST”

A grease-filled die caused the “T” in “TRUST” to be partially or entirely obscured. While amusing, this error is highly collectible due to its oddity.

How to Spot It

• Examine the phrase “IN GOD WE TRUST” for partial or missing “T”
• Check both circulated and uncirculated Kansas quarters
