Misprinted Money: How to Identify Printing Errors on Currency

Misprinted money refers to paper currency with printing defects that occurred during the manufacturing process at the Bureau of Engraving and Printing. These errors range from subtle overprint misalignments to dramatic missing prints that leave portions of the note blank. Understanding what constitutes a genuine misprint helps you spot finds that other people overlook.

What This Means

A misprint is any deviation from the intended design that results from a malfunction or mistake during the printing process. US currency goes through multiple printing stages — back printing, face printing, and overprinting (serial numbers, seals). Errors can occur at any of these stages, producing distinct types of misprints with different visual characteristics.

What to Look For

• Offset printing — design from one note transfers as a ghost image onto another
• Missing first print — no back design (blank back)
• Missing second print — no face design
• Missing third print — no serial numbers, Treasury seal, or Federal Reserve seal
• Double printing — design printed twice, slightly offset
• Ink smearing — wet ink transferred during stacking or handling
• Insufficient inking — parts of the design printed too lightly or not at all
• Board breaks — white streaks from cracks in the printing plate

Common Mistakes to Avoid

• Calling water-damaged or faded bills "misprints" — environmental damage is not a production error
• Assuming any unusual-looking bill is misprinted without understanding the specific error types
• Not realizing that different eras of currency used different printing methods
• Confusing chemical alteration with genuine missing ink
• Cleaning or pressing error notes — this can damage them and reduce value

What Affects Value

Misprint values are driven by the type of error, its severity, and condition. A note missing its entire back printing is worth far more than one with a slight overprint shift. The denomination also matters — misprints on uncommon denominations or older series tend to command higher prices. Crisp, uncirculated misprints are most desirable.
