How to Identify the Lincoln Shield Cent

What It Is

The Lincoln Shield Cent is the current U.S. one-cent coin, struck every year since 2010. It keeps Victor David Brenner's original 1909 Lincoln portrait on the obverse but replaced the Lincoln Memorial reverse (used 1959-2008) and the four special 2009 Bicentennial reverses with a permanent Union Shield design intended to represent Lincoln's role in preserving the nation.

Obverse Design

Abraham Lincoln faces right in profile, filling most of the field. "IN GOD WE TRUST" arches above his head, "LIBERTY" sits to the left, and the date appears to the right of his shoulder, just above where a mint mark would be added. This layout, including the placement of the motto and legend, has been unchanged in basic form since 1909, so at a glance the obverse looks the same as it does on Wheat and Memorial cents from decades earlier.

Reverse Design

The reverse shows a Union Shield made of thirteen vertical stripes, symbolizing the states joined into one nation under Lincoln's leadership. A ribbon-like banner reading "E PLURIBUS UNUM" stretches horizontally across the top of the shield, appearing to be tucked behind it. "ONE CENT" is inscribed in small letters across the lower portion of the shield itself, and "UNITED STATES OF AMERICA" arches around the upper rim of the coin above the shield.

Size, Weight, and Metal

Like all cents made since the 1982 alloy change, it is copper-plated zinc: a zinc core making up about 97.5% of the coin's mass, with a thin copper coating of about 2.5%. It weighs 2.5 grams, measures 19.05 mm across, and has a plain, smooth edge with no reeding or lettering.

Mint Marks

Look just below the date on the obverse. A "D" marks a Denver strike. No mint mark at all, or a "P" (introduced in 2017 for the first time on a circulating cent, to mark the Mint's 225th anniversary), indicates a Philadelphia strike. Proof coins sold directly to collectors carry an "S" for San Francisco and are typically found only in specially packaged proof sets, not in circulation.

Telling It Apart From Similar Cents

Since the obverse portrait hasn't changed in over a century, the reverse is the fastest way to date a Lincoln cent at a glance: the Wheat Cent (1909-1958) shows two curved wheat stalks; the Memorial Cent (1959-2008) shows the Lincoln Memorial building with columns; the 2009 Bicentennial cents show four different scenes from Lincoln's life; and only coins struck from 2010 onward show the Union Shield.

Judging Condition

On a well-preserved coin, the shield's vertical lines should be sharp and distinct from one another, and Lincoln's hair, ear, and coat details should be crisp with visible separation. Heavy wear gradually flattens the shield lines into a smoother, less defined surface and rounds off the details of Lincoln's cheek and jawline. Because these are common, recently made coins, most examples found in circulation show only light to moderate wear rather than serious damage.

Authenticity Notes

These are mass-produced, low-value modern coins, so outright counterfeiting is uncommon. Issues you're more likely to encounter are environmental damage, such as corrosion or discoloration from the zinc core oxidizing where the copper plating has worn through or been scratched, or coins that have been chemically cleaned, which leaves an unnaturally shiny, dull, or uniformly colored surface instead of the varied tone of natural wear.
