How to Spot a Million-Dollar Bicentennial Half
Step 1: The Magnet Test (5 Seconds)

- Clad coins weakly attract (nickel-copper)
Step 2: Look for These Errors
Double-Struck: Overlapping designs (tilt in light)
Missing Clad Layer: Copper shows through (weighs less)
“Spitting Eagle” Die Crack: Line through eagle’s beak
Step 3: Grade the Condition

- Original red packaging adds 50% premium
