Step-by-Step: How to Spot Million-Dollar Error Coins
Not all coins are created equal. Some carry minting mistakes that make them insanely valuable.
Here are the top coin errors every collector (or curious spender) should know 
The Missing Mintmark Miracle (Value: $100,000+)
What to look for: A coin missing its mintmark (“P,” “D,” or “S”).
Where to check:
- Quarters: Right of Washington’s ponytail
- Nickels: Near Monticello (reverse side)
- Pennies: Just below the date
Pro tip: Use a 10x magnifying glass to boost your chances of spotting this rare beauty.
The Wrong Planchet Jackpot (Value: $250,000+)
This happens when a coin is struck on the wrong metal planchet.
Clues to watch for:
- Wrong size (e.g., a dime that’s quarter-sized)
- Unusual weight (lighter or heavier)
- Odd color (like a silver penny or copper nickel)
Famous Example:
A 1965 quarter struck on a 90% silver planchet sold for a whopping $1.5 million in 2022! 
The Double Denomination Dream (Value: $500,000+)
This ultra-rare error shows two coin designs on one piece.
Example:
A Jefferson nickel front with a Roosevelt dime back — true collector’s gold!
Record Sale:
A 2000-P Sacagawea Dollar/Washington Quarter mule coin fetched $192,000 at auction.

Found Something? Here’s What to Do Next
