Some rare one-dollar bills can be worth very high amounts to collectors when they have unique features. Examples include notes with extremely low serial numbers, special repeating or “fancy” patterns, or dramatic printing errors. Certain historical series, like star notes from limited runs or misprints where two denominations overlap, can command six-figure prices at auction. Condition matters enormously; bills graded as nearly perfect and uncirculated typically fetch the highest valuations. Provenance and demand among specialized collectors also influence value. While not every unusual dollar is priceless, a genuinely rare and pristine error note could be appraised around one hundred fifty thousand dollars
