Identification Tips

Look for obvious doubling on the obverse, especially on "LIBERTY", the date "1955", and "IN GOD WE TRUST". The doubling should be clear and dramatic, not weak or questionable. The reverse is normal. Beware of mechanical doubling (damage) or worthless counterfeits. Authentication recommended for expensive examples.

Historical Context

This error occurred at the Philadelphia Mint when a misaligned hub created a doubled die that was used to strike approximately 20,000-24,000 pennies before being discovered. Most entered circulation mixed with cigarette vending machine change. The mint chose not to destroy them, making this error legendary among collectors.

Frequently Asked Questions

How do I know if I have a real 1955 Doubled Die penny?

The doubling must be strong and clear, especially on "LIBERTY" and the date. Use a magnifying glass - you should see complete, separated duplicate images. Many fakes exist, so consider professional authentication for valuable finds. Compare to verified images online.

What causes a doubled die error?

A doubled die error occurs when the die used to strike coins receives a double impression from the hub during die production, with slight misalignment between impressions. This creates permanent doubling on every coin struck by that die.
