United States 1985 — 5 Dollars Federal Reserve Note, Cleveland District (Friedberg 1978-D) Insufficient Inking on Back Error, PMG 64 EPQ Choice Uncirculated

A visually striking Insufficient Inking Error on this 1985 5 Dollars Federal Reserve Note from the Cleveland District (Friedberg 1978-D, DB Block) leaves nearly two-thirds of the reverse design ghosted or missing. The left portion of the intaglio printing—normally displaying the numeral '5,' frame ornamentation, and portions of the Lincoln Memorial vignette—shows only a faint outline where the press failed to transfer adequate ink to the paper. This form of printing error occurs when the intaglio press cylinder is inadequately charged with ink before an impression cycle. ... Read more →

United States 1988A — 1 Dollar Federal Reserve Note, Chicago District (Friedberg 1915-G) Insufficient Inking Error, PMG 64 EPQ Choice Uncirculated

This 1988A 1 Dollar Federal Reserve Note from the Chicago District (Friedberg 1915-G, GE Block) displays a dramatic Insufficient Inking Error that left much of the upper design on the obverse faint or missing. The portrait of George Washington remains clear and fully struck, but the border engraving, serial zone, and areas above the central vignette show patchy or absent ink transfer. This occurred during the intaglio face printing pass when the plate failed to receive an even ink layer or when the wiping cylinder overcleaned the plate prior to impression. ... Read more →

This 1993 20 Dollars Federal Reserve Note from the Chicago District (Friedberg 2080-G, GA Block) represents one of the Bureau of Engraving and Printing’s most visually dynamic mechanical failures—a genuine Printed Tear Error, preserved in fully original condition. The note exhibits two sharply folded and partially torn corners that became creased before entering the final printing pass. When the sheet was fed into the intaglio press, the torn and folded segments prevented ink from transferring to those areas, leaving distinctive blank voids and offset impressions once unfolded. ...
