The Denver Mint struck Lincoln pennies in 1918 to keep up with heavy wartime commerce.
These classic wheat pennies feature Victor David Brenner's portrait of Abraham Lincoln on the front.
The reverse displays two stalks of wheat framing the denomination.
Most copper cents produced during this era went straight into everyday circulation.
People spent them constantly on daily goods and services.
As a result, finding an early Denver strike that avoided pocket wear is exceptionally difficult.
The original copper metal also reacts quickly to moisture and air over time.
That chemical reaction naturally turns bright red copper into brown or chocolate tones.
A piece from 1918 that keeps its full original mint luster stands out instantly from ordinary survivors.
Heritage Auctions handled the sale of a premier certified specimen of this date.
The coin crossed the auction block with an MS67 RD grade designation.
The auction listing achieved a record price benchmark recorded in January 2019.
The grade of 67 means the coin shows almost zero handling marks under close inspection.
It remains in pristine condition just as it looked the day it left the coin press.
The "RD" label stands for Full Red color.
Grading services award this color code only when a copper penny retains at least ninety-five percent of its original mint redness.
Top collectors compete vigorously whenever a vintage branch-mint cent appears at this elite level of preservation.
Condition rarity is the main factor behind the strong market value of this issue.
While millions of Lincoln cents were made in 1918, very few were set aside immediately by collectors.
The coin collecting hobby was far smaller back then than it is now.
Early Denver Mint strikes are notorious for weak die pressure and surface spotting.
Finding a strike with crisp design details is rare on its own.
Preserving that sharp strike without any dark tarnish or contact marks for a century is even harder.
Only a tiny fraction of surviving coins qualify for a Superb Gem grade.
Lincoln cent enthusiasts building registry sets need top-grade survivors to complete their collections.
That intense collector demand pushes prices upward whenever an exceptional example appears on the market.
Average worn examples found in pocket change carry only a small fraction of this certified value.
You can inspect your own 1918 penny using basic numismatic tools.
Start by checking the date on the right side of Lincoln's bust.
Look directly below the year 1918 to locate the small "D" mintmark.
That letter shows the coin came from the Denver facility rather than Philadelphia or San Francisco.
Use a five-power or ten-power jeweler loupe to examine the metal surfaces.
Check the highest points of the coin for signs of friction.
On the front, examine Lincoln's cheekbone and the hair above his ear.
On the back, look closely at the upper tips of the wheat stalks.
Any dull flatness on those spots indicates circulation wear.
Pay close attention to the surface color under a good desk lamp.
A brown coin has darkened with age, while a true red coin shines with warm copper brilliance.
