Welcome to Constellation Numismatic's online error currency catalogue. While some dealers view errors as little more than a nuisance, we specialize in U.S. rare paper money errors, striving to offer a diversity of error types, selection of grades, and a wide range of prices. Our hope is to reach both the novice collector and advanced connoisseur alike.
Error paper money is a fascinating specialty within the spectrum of numismatics. While not as popular as error coin collecting, the field of misprinted paper money presents a fun and educational pastime. Educational in that it is a valuable tool in understanding the sometimes intimidating, at least on the surface, technical side of how currency is produced at the Bureau of Engraving and Printing. Paper money misprints can form a stand alone collection, assembled by series, denomination, or error class, just to name a few, or complement a "normal" rare currency collection.
Misprinted currency is nearly as old as paper money itself. U.S. currency errors probably exist on all modern series small size notes, from the one dollar up to at least the one thousand dollar denomination, and on the majority of early large size note issues, including national bank notes, and even fractional currency, obsolete notes, and continental currency and colonial issues as well. Currency misprints can occur from failures both human and mechanical. Results can be subtle or eye-catching, and sometimes quite bizarre or unique.
