1955 Doubled Die Penny Value
The 1955 Doubled Die Obverse is one of the most celebrated error coins in US numismatics. Strong doubling is visible to the naked eye on the date and lettering (“LIBERTY”, “IN GOD WE TRUST”).
Key facts
- Cause: a misaligned hub created dramatic doubling on the obverse during die production.
- Visible without magnification — bold doubling of the date and inscriptions.
- A genuine 1955 DDO is valuable in every grade; many fakes and lesser “machine doubling” coins are mistaken for it.
