This 1993 20 Dollars Federal Reserve Note from the New York District (Friedberg 2079-B, BD Block) is a superbly preserved example of an Insufficient Inking Error that drastically weakens the reverse printing. The normally dark green depiction of the White House appears faint and washed out, with many architectural and background details missing.

This 1974 1 Dollar Federal Reserve Note from the Chicago District (Friedberg 1908-G, GD Block) presents a distinct Paper Jam Error—an uncommon and revealing production mishap that occurs when the currency paper fails to feed smoothly through the intaglio press or overprint unit. The result is a wrinkled or crumpled section of paper that becomes permanently flattened into the design, often distorting part of the printed image or leaving telltale creases and folds embedded beneath the ink. The Bureau of Engraving and Printing’s multi-stage process involves extremely fine tolerances, with paper sheets passing at high speed through multiple presses—first for back printing, then face, and finally for seals and serials. ...
