The Famous $51 Million Bicentennial Quarter

Why Is This Quarter Worth $51 Million?
Even though millions of these quarters were minted, only a very limited quantity were struck in unique error conditions or with exotic metallic composition. The $51 million example had:
- A double die error
- Struck in 90% silver (instead of the normal clad)
- Near mint condition (graded MS-68 or better)
- Special history or provenance
These traits all combined to create a genuinely one-of-a-kind item that sold at auction to a luxury collector for a record price.
5 More Rare Coins That Could Be Worth Big Money
1. 1943 Copper Lincoln Penny
- Estimated Value: $100,000 to $1.7 million
- Why It’s Rare: In WWII, pennies in 1943 were made from zinc-plated steel due to a lack of copper. A small number of copper planchets were inadvertently produced, making them extremely scarce.
- How to Identify: Place it on a magnet. If it sticks, it’s steel. If not, you’ve got a gold nugget hiding.

2. 2004 Wisconsin Extra Leaf Quarter
- Value Estimated: $200 to $6,000+
- Why It’s Rare: A mint error caused several coins to have an extra leaf on the corn stalk of the back.
- Two Types: “High Leaf” and “Low Leaf” types are both worth collecting.
3. 1969-S Lincoln Cent Doubled Die Obverse
- Estimated Value: $35,000 to $110,000
- Why It’s Rare: The date and the word “LIBERTY” appear doubled because they were slightly out of alignment during minting.
- Very sought after by numismatists.
4. 1955 Doubled Die Lincoln Cent
- Estimated Value: $1,000 to $20,000+
- Why It’s Rare: Immaculate doubling of the text on the obverse renders it a highlight error coin.
- Tip: “IN GOD WE TRUST” and “LIBERTY” seem to have been printed double.
5. 1999-P Connecticut Quarter with Broadstrike Error
- Estimated Value: $200 to $2,000
- Why It’s Rare: A broadstrike error causes the coin to spread wider than its regular shape.
- Such a mint error is rare and striking.

How to Spot a Rare Coin in Your Collection
Rare coins are typically unseen because most people have no idea what to look for. Some guidance follows:
Look for:
- Unusual designs or incorrect details
- Doubling of numbers or letters
- Mint marks from rare mints like “S” (San Francisco) or “D” (Denver)
- Coins from key years (e.g., 1943, 1955, 1976)
- Error coins (e.g., missing edge lettering, off-center strikes)
Tools to Use:
- Magnifying glass or jeweler’s loupe
- Digital coin scale
- Check reference books or coin appraisers
Where to Sell or Appraise Rare Coins
