Doubled die errors originate during the die-manufacturing process, not during the actual coin strike. A working die is impressed by a hub multiple times; if the die shifts even slightly between impressions, every detail on that die — letters, numerals, portrait features — will carry a doubled image. Every coin struck from that die will show the same doubling in the same location, which is what distinguishes a genuine doubled die from ordinary machine doubling.
On 2022 Lincoln cents, doubled die obverse (DDO) examples show the most visible doubling on "LIBERTY" and "IN GOD WE TRUST," with secondary images on Lincoln's hair and portrait details. Doubled die reverse (DDR) specimens exhibit doubling on "ONE CENT," "UNITED STATES OF AMERICA," and on the horizontal stripes of the Union Shield — the shield's clean geometric lines make doubling particularly easy to identify under a 10× loupe.
Value scales sharply with the prominence of the doubling. Subtle examples visible only under magnification bring $25–$50, while strong doubling visible to the naked eye can command $100–$150 or more. A documented 2022-D DDR showing bold doubling on "ONE CENT" and shield stripes is worth at least $50 uncirculated. Shield doubled die errors are considered particularly scarce within the modern Lincoln series because the geometric reverse design makes manufacturing tolerances more critical.
Grease-filled die errors occur when a film of lubricant, carbon buildup, or debris accumulates in the recessed portions of a working die. During striking, the compressed grease prevents the coin metal from flowing into those recessed areas, resulting in weak or entirely missing design elements on the finished coin. The thicker and more complete the grease fill, the more dramatically the design elements disappear — a well-filled die can produce a coin that appears completely blank in affected areas.
The most dramatic documented 2022 grease fill error affects the reverse legend "UNITED STATES OF AMERICA," with the lettering either partially or entirely missing from the coin's surface. The die appears to have been clogged in the area of the reverse legend, and multiple examples of this specific variety have been confirmed. Because the missing letters are in a highly visible location on a well-known design, these coins are immediately recognizable as errors even to non-specialists.
A 2022 Lincoln Shield cent with the words "UNITED STATES" completely absent from the reverse has been documented and valued at up to $375 — making it the highest-value grease fill error confirmed for this date. A related variety, the 2022-P "Extra V" error (an additional letter impression near Lincoln's portrait, attributed to a struck-through or hub anomaly), is valued at approximately $30 in circulated condition and $45 or more in uncirculated grades.
Die cracks occur when the immense pressure of repeated striking causes a working die to develop fractures. As the die continues in service, metal from the planchet flows into these cracks during each strike, leaving a raised line — sometimes called a "die break" — on every coin produced afterward. Minor hairline cracks add only modest value, but dramatic cracks that progress toward the coin's edge can eventually produce a full "cud" — a large raised blob — which commands the highest premiums.
The most significant documented 2022 die crack variety affects the reverse of Denver-minted cents, with a prominent crack running through the Union Shield design. The shield's grid of horizontal bars and vertical lines provides an ideal diagnostic background for identifying die cracks, since any raised line crossing the shield stripes is immediately visible. This specific variety — sometimes called the "2022-D Shield Die Crack" — stands out for the dramatic placement of the crack directly across the coin's central design element.
Value ranges from $5–$25 for minor hairline cracks to $100–$300+ for major die breaks. The documented 2022-D shield die crack, due to its prominent location and visual impact through the geometric reverse design, has been valued at up to $390 — significantly above typical die crack prices for modern Lincoln cents. The famous "BIE" variety (a chip between "B" and "E" in "LIBERTY" creating a spurious "I") is worth a more modest $5–$25 on 2022 examples.
Off-center strikes occur when a coin blank (planchet) is not fully seated within the collar die at the moment of striking. The result is a coin where the design is partially missing — struck off to one side — leaving a characteristic crescent-shaped blank area of unstruck planchet metal. The extent of the misalignment is described as a percentage: a 5% off-center coin barely shifts the design, while a 50% off-center leaves half the coin completely blank.
The most desirable off-center strikes for collectors are those showing a dramatic percentage of misalignment — typically 30% to 60% — while still retaining a complete, legible date. Without the date visible, an off-center coin loses most of its collector premium, since the date is the primary identifier for attribution and valuation purposes. A 2022-D penny with approximately 20% off-center strike combined with a partial collar error — where one side of the edge appears thicker due to the collar's partial engagement — is a particularly well-documented variety.
Values run $15–$25 for modest 10–15% off-center examples to $100 or more for dramatic 40–60% examples with a full visible date. The documented 2022-D 20% off-center with partial collar has been valued at $14–$20. Related striking anomalies include broadstruck coins (struck entirely outside the retaining collar, creating a wider, thinner coin) and die clashes (when dies strike each other without a planchet between them, transferring mirror images onto each die's working surface).
Struck-through errors result when a foreign object — a piece of wire, cloth fiber, debris, or lubricant — becomes caught between the die and the planchet at the moment of striking. The object is pressed into the coin's surface, leaving a negative impression of its shape and texture. Unlike post-mint damage (which shows metal displacement and sharp edges), a genuine struck-through error has clean, even borders because the foreign object was soft relative to the coin metal at the moment of pressure.
The most collectible 2022 struck-through variety is nicknamed "Lincoln's Assassination" by the error coin community — the foreign object's impression appears on Lincoln's forehead area in a position suggesting the trajectory of a projectile aimed at the president, an eerie coincidence given Lincoln's actual assassination. This 2022-P specimen, graded Brilliant Red uncirculated, has been valued at $18–$20. A second unusual variety, the "Feeder Finger Error," shows the impression of the press's mechanical feeder finger mechanism on the coin surface — a rare curiosity documenting the very machinery that struck the coin.
Struck-through errors range from minor (worth $10–$30 for small, subtle impressions) to highly dramatic for large or thematically interesting impressions. The Crying Lincoln variety — a doubled die combined with a die chop impression creating the appearance of a tear below Lincoln's eye — has been valued at $40–$50. The "Feeder Finger" variant is also documented in the $18–$20 range for uncirculated examples, similar to the "Lincoln's Assassination" piece.
Defective plating errors are a category unique to post-1982 copper-plated zinc cents — they simply could not have existed on the older solid copper coins. The modern Lincoln cent is produced by electroplating a zinc blank with a thin layer of copper (about 8 micrometers thick). When the electroplating process fails — either because a planchet is improperly prepared, inadequately cleaned, or passes through the plating tank too quickly — the copper bonding can fail or be entirely absent in affected areas.
On documented 2022-D examples, some specimens show the reverse entirely missing its copper layer, exposing the bright, silvery zinc core beneath. The resulting two-tone appearance — copper-orange obverse against a zinc-silver reverse — is immediately recognizable and impossible to fake convincingly. Other forms of defective plating include plating blisters (small raised bubbles where the copper layer is delaminating from the zinc core) and lamination errors (where the plating peels away, sometimes removing design elements with it).
Values for defective plating errors vary considerably based on the extent and visibility of the plating defect and the coin's overall grade. A small plating blister adds modest value ($5–$25); a coin with the entire reverse missing its copper plating, graded uncirculated and authenticated, can command $25–$150 or more depending on condition. These errors are genuinely scarce because the U.S. Mint's plating line is equipped with sensors to detect and reject improperly plated blanks — specimens that escape represent true quality control failures.
