Explore the intriguing world of U.S. one-dollar bill errors with our guide, uncovering the rare misprints that elevate everyday currency to collectible treasures.

Error Types:
Misaligned Overprint: The seal and serial numbers are printed outside their designated area, often overlapping with other elements.
Inverted Overprint: The treasury seal and serial numbers are printed upside-down, a result of an error in the printing process.
Missing Overprint: A bill lacking the treasury seal and serial numbers, making it highly unusual and collectible.
Mismatched Serial Numbers: A bill with non-matching serial numbers on the left and right sides.
Insufficient Inking: Parts of the bill's design are faint or missing due to inadequate inking during the printing process.
Overly Inked Design: The bill's design appears overly dark, caused by too much ink being applied.
Blank Reverse: One side of the bill is completely blank, due to a sheet not being flipped during the two-sided printing process.
Foldover Error: A portion of the bill was folded during printing, resulting in a blank spot where the fold prevented ink from applying.
Offset Printing Error: The impression of one side of the bill is mistakenly printed on the reverse side, creating a mirrored effect.
Star Note Misprint: Star notes are replacements for misprinted bills, but sometimes these too can have errors, making them doubly unique.
