The 2016 Penny Value Guide: What Your Lincoln Shield Cent Is Really Worth

The doubled die obverse results from a misalignment between the working hub and working die during the hubbing process. When the die receives a second impression at a rotated or shifted angle, the design elements are duplicated in the die steel itself — meaning every coin struck from that die will carry the doubling permanently.

On 2016 DDO specimens, the clearest doubling typically appears on the word LIBERTY or the inscription IN GOD WE TRUST. Under a 10× loupe, look for a distinct raised secondary image that has visible depth — true hub doubling produces a three-dimensional effect, while mechanical doubling (machine doubling damage) leaves only a flat shelf with no numismatic value.

Collector demand for 2016 DDO coins is strong because the date is modern and coins are easily sourced from circulation for comparison. Strong examples in uncirculated grade with RD color command $300–$650, and professionally graded specimens consistently outperform raw coins at auction.

An off-center strike occurs when the planchet (blank) is not properly centered beneath the dies at the moment of striking. The coin passes through the collar without being restrained correctly, so only a portion of the design is imprinted. The resulting coin shows the Lincoln design shifted toward one side with a crescent-shaped area of unstruck metal visible.

Value increases dramatically with the percentage of off-center shift and whether the date is visible. A coin that is 10–20% off-center with a readable date is worth $25–$75. Coins that are 40–60% off-center — enough to show a dramatic blank crescent while still displaying the date — can bring $100–$200 or more. Coins that are more than 50% off-center without a visible date are less desirable despite appearing more dramatic.

Off-center strikes on modern cents are well-documented and easily authenticated by professional graders. The absence of a complete collar strike and the visible blank area make authentication straightforward with basic examination.

A broad strike occurs when the retaining collar — the steel ring that surrounds the planchet during striking and gives the coin its proper diameter and reeded or plain edge — fails to engage or is entirely absent. Without the collar's restraint, the metal spreads outward beyond the normal 19mm diameter under the force of the dies.

The resulting coin is visibly wider and thinner than a normal cent, and the rim will be flat, weakly defined, or nearly absent because the collar never formed it. The design elements remain intact but may appear slightly spread or weakened at the periphery. A broad strike 2016 penny will measure noticeably larger than 19mm — typically 20–22mm or more.

Broad strikes are among the easiest errors to authenticate because the diagnostic evidence (oversized diameter, flat rim, undisturbed design) is self-explanatory under basic inspection. Uncirculated examples with the design centered and full RD color attract the most collector interest at auction.

Lamination errors occur when the zinc core of the copper-plated planchet has internal contaminants, gas pockets, or impurities that were present in the metal strip before it was punched into blanks. During or after striking, these subsurface defects cause the copper plating or sections of the zinc core to separate, peel, or flake away from the main body of the coin.

The visible result is a crack, split, or peeling flap of metal on the coin's surface — sometimes the flap remains attached, creating a raised ridge; other times it has fallen away entirely, leaving a void with distinctive edges. Lamination errors can appear on either the obverse or reverse. Coins with large, dramatic flaps still attached to the surface are most valuable because the evidence of the error is visually dramatic and clearly pre-mint in origin.

Because the 2016 cent uses a copper-clad zinc construction, lamination errors are more prevalent on modern cents than on pre-1982 solid copper issues. Collectors prize examples that show deep, multi-layer separation rather than superficial surface blemishes, which can sometimes be confused with post-mint damage.

Die cracks develop over the working life of a die as the hardened steel fatigues from repeated hammer blows. As the die steel fractures, raised metal ridges appear on every coin struck from that die — the crack in the die creates a valley that fills with metal during striking, leaving a raised line on the coin's surface. Early die state coins show thin crack lines; late die state coins may show multiple heavy cracks throughout the design.

The most dramatic form of this error is a rim cud — a raised, blobby lump of metal at or near the rim caused by a chunk of the die breaking away entirely. The missing die steel creates a void that fills completely with planchet metal during the strike, producing an irregular raised mass at the coin's edge that clearly overruns the normal rim design. Rim cuds near Lincoln's portrait or a major design element are the most prized.

Die cracks are common on high-volume production years like 2016, where dies are pushed through enormous mintages. Rim cuds, being more dramatic and requiring an actual piece of the die to break off, are less common and generate more collector enthusiasm. The location and size of the cud or crack determines value — prominent, well-placed examples bring the highest premiums.

The misplaced mint mark error occurs when the punch used to add the mint mark to the working die is pressed into the die steel at an incorrect location — either at a shifted position, in a design element, or in the coin's field. Since 2016 is the last year Philadelphia omitted the "P" mint mark, misplaced mint mark errors are exclusive to Denver "D" issues (and hypothetically could appear within the date numerals or elsewhere on the design).

To identify a genuine MPM, examine the area around and within the date numerals using a 10× loupe or coin microscope. A misplaced "D" punch may appear as a faint but raised "D" impression within a digit of the date, in the field below or above the normal mint mark position, or overlapping into Lincoln's neck truncation. The impression should be clearly a letter punch, not a die gouge or damage mark.

Misplaced mint mark errors are under-documented on modern cents compared to classic era coinage, making confirmed specimens particularly interesting to specialists. Because the mint mark was applied mechanically on modern production dies, true MPMs from 2016 are genuine varieties worth pursuing with careful examination of Denver-mint examples.
