1999 Lincoln Cent Off-Center Error: Small Coin, Big Money
If you think pennies are just spare change, think again. Certain 1999 Lincoln pennies with off-center strike errors are bringing in thousands of dollars.
These errors occur when the blank coin (called a planchet) is improperly placed during the minting process. This results in coins that show only a portion of the design, often with dramatic visual appeal.
- Highly valuable examples: Coins struck 50% to 90% off-center with a full visible date are the most valuable.
- Recent sale: An 80% off-center 1999 penny sold for $913 at a 2023 Heritage Auctions event.
- Top-tier value: Cleaner examples have fetched up to $2,500-$3,000 in private deals.
These rare pennies have even been found in regular change, making them a real treasure for anyone willing to look closely.

The 1999-W $5 Gold Eagle coin is a precious metal coin that became even more valuable due to a minting error. This rare variety is known as the “Unpolished Die” variety.
- What makes it rare: A section of the die used to mint the coin wasn’t polished properly, creating streaks across Liberty’s face and neck.
- Value range: These coins can sell for anywhere between $2,500 to over $14,000, depending on their condition.
