Currency errors have captured the interest of collectors and investors, with certain misprinted bills and coins now valued far above their face amounts. Whether a minor misalignment or a dramatic mismatch, these errors are often hidden treasures. Let’s dive into some of the most valuable U.S. currency errors that could potentially be worth a fortune.
Inverted Third Printing Errors
Inverted third printing errors are among the most iconic and sought-after currency mistakes. This occurs when the front elements of a bill, such as the treasury seal and serial number, are printed upside-down. Commonly found on older U.S. denominations like $20 or $50 bills, these errors are rare and highly prized by collectors. Due to their scarcity, bills with inverted third printing errors can reach values over $35,000.
Double Denomination Errors
Double denomination errors involve an unusual twist—two different denominations appearing on one bill. For example, a bill might show the front of a $10 bill and the back of a $5 bill, resulting in a highly distinctive and collectible piece. These rare errors are generally well-preserved by collectors, and their unique nature often fetches over $100,000 at auction.
Misaligned Overprint Errors
Misaligned overprints are characterized by off-center seals and serial numbers due to misaligned printing plates during the final phase of production. This type of error can appear on a range of denominations. The degree of misalignment and the overall condition of the bill determine its value, with some misaligned overprint bills valued between $15,000 and $30,000 at auction.
Cutting Errors
Cutting errors occur when currency sheets are improperly cut, resulting in bills with missing sections or extra margins. These errors can be highly valuable, especially those with an off-centered white margin or parts of neighboring notes. Bills with cutting errors can reach values of $5,000 to $10,000, depending on the denomination and condition, with higher-grade examples drawing even more attention from collectors.
Star Note Errors
Star notes are printed as replacements for bills damaged during production and are marked by a small star beside the serial number. Occasionally, an error occurs on these replacement notes, making them doubly rare and highly collectible. Error star notes from older series or in higher denominations can be worth thousands of dollars, especially in uncirculated condition.
Foldover Errors
Foldover errors happen when part of a bill is folded during printing, resulting in a portion of the design appearing on the wrong area. These mistakes create unique visuals, adding to their appeal. Foldover errors on higher-denomination bills are particularly rare and can fetch prices around $20,000 or more, depending on the severity of the misprint and the bill’s overall condition.
Mismatched Serial Numbers
One of the most unique errors, mismatched serial numbers, occurs when the serial numbers on a bill do not match. This glitch is highly unusual and highly prized among collectors. A mismatched serial number error on a $100 bill, for example, has sold for up to $100,000 based on the year and condition of the bill.
