The 1985-D Lincoln cent is a common coin with an uncommon top tier.
The United States Mint struck these pennies in Denver during the 1985 production run.
By this time, the Mint made pennies mostly out of zinc with a thin outer layer of pure copper.
Denver produced billions of these pennies for daily commerce and pocket change.
Most of them circulated heavily and quickly picked up scratches, stains, and ugly spots.
Finding an ordinary 1985-D penny in your change is easy.
Finding one that survived in flawless, factory-fresh condition is a completely different story.
The RD designation stands for Red, which means the coin still shows its original bright copper color.
An extraordinary example of the 1985-D RD cent reached a standout price of 6/10 at auction.
The sale was handled by the auction house BM.
Professional coin graders certified this record-breaking piece at the stunning grade of 69.
A grade of 69 is on the Sheldon 70-point coin grading scale.
This means the coin is virtually perfect with no visible flaws to the naked eye.
Even under strong magnification, a coin at this level shows almost zero contact marks or strike errors.
Collectors pay premium prices when a coin reaches the absolute ceiling of quality for its date.
High-grade registry set builders often compete aggressively for these top-graded pieces.
The value of this specific coin comes down entirely to condition rarity.
The Denver Mint did not handle regular pennies with special care in 1985.
High-speed coin presses dropped fresh cents into large metal bins where they banged into each other.
The copper-plated zinc composition also made the surfaces soft and prone to contact marks.
Zinc cents from the mid-1980s are notorious for developing zinc rot and dark spots over time.
Because of these factors, nearly every 1985-D cent degraded before it could be preserved.
Very few people thought to search rolls and save pristine examples back when they were new.
A specimen that survived four decades without a single noticeable mark is an extreme anomaly.
When intense collector demand meets a population of almost zero, prices skyrocket.
You can check your own 1985 pennies at home with a few simple steps.
First, look at the front of the coin directly below the date 1985.
You should see a small D mintmark stamped under the date numbers.
Next, use a 10x magnifying glass or a jeweler loupe under a good light source.
Inspect the high points of Lincoln bust, including his cheek, shoulder, and hair.
Look for any signs of wear, hairline scratches, or small contact hits from other coins.
Check the color across both the front and the back of the penny.
To qualify as Red, the surfaces must show at least 95 percent of their original fiery luster.
If you have a pile of shiny pennies and want a fast first pass, you can scan them using Coin Value Checker to see if any are worth a closer look.
Keep in mind that normal pocket change will not grade near 69.
Only an uncirculated penny that has been protected from air and handling since 1985 has a shot at top tier value.
