The Denver Mint struck this Lincoln cent back in 1920.
World War I had recently ended, and the United States economy was moving quickly.
Denver produced tens of millions of pennies that year to keep up with daily business needs.
Most of these coins went straight into circulation to buy newspapers, candy, and bus rides.
Finding a 1920 penny from Denver is not especially hard if you look at worn coins.
The difficulty begins when you look for one that never circulated.
The copper used during this era was prone to spots, streaks, and uneven color.
Denver in particular often struggled with softer strikes and worn dies during the early 1920s.
That makes an original, fully red example from this date quite special to collectors.
A top-tier example of this penny made numismatic news when it crossed the block at Heritage Auctions.
The sale took place in a 2/07 auction event, drawing attention from serious Lincoln cent specialists.
Grading experts evaluated the coin and certified it at the Mint State 66 level.
A grade of 66 means the coin has crisp details and only the tiniest handling marks visible under a glass.
The coin also earned the full Red designation, often shortened to RD.
A Red grade means the copper retains at least ninety-five percent of its original bright mint luster.
Top collectors compete aggressively when a piece with this level of preservation appears at a major auction house like HA.
Most surviving 1920-D pennies turned brown decades ago, so this high grade commanded serious interest.
Raw mintage numbers only tell a small part of the story for early branch-mint Lincolns.
Back in 1920, very few collectors saved new coins straight from the Denver Mint in full rolls.
The few pieces that were saved often sat in paper envelopes or damp drawers.
Copper reacts easily with moisture and air, turning dark brown over time.
Because of this chemical reaction, true Red coins from the 1920s are condition rarities.
Even among uncirculated pieces, weak strikes around the wheat stalks and Lincoln's hair are very common.
A specimen that combines a sharp strike with pristine surfaces and bright orange-red luster is an extreme outlier.
Demand from collectors building complete, high-grade registry sets pushes prices upward whenever one appears.
Record prices belong only to these finest known survivors, not ordinary pocket-change finds.
Start your inspection by checking the date on the front of the coin, right below Lincoln's bust.
Look directly underneath the numerals 1920 for the small "D" mintmark.
If there is no letter below the date, the coin was struck in Philadelphia instead of Denver.
Next, use a good 5x or 10x magnifying glass to inspect the surface color and quality.
Check the highest points on the design, including Lincoln's cheekbone and the tips of the wheat stalks on the back.
Any flatness or shine loss on those high points means the coin has seen circulation wear.
Take note of the color, distinguishing between dark brown, mellow red-brown, and bright copper-orange.
If you have trouble telling whether your coin retains original mint luster, using the CoinKnow app can give you a helpful first assessment.
You can also check the piece with Coin Value Checker to compare your coin against certified grades.
Remember that worn, brown examples from old jars are common and trade for modest sums, while only pristine red specimens reach record levels.
