The Denver Mint struck the 1986-D Lincoln cent as a standard circulating coin.
Like other pennies from this era, it features the classic bust of Abraham Lincoln on the front and the Lincoln Memorial on the back.
The "D" mint mark sits right below the date on the obverse side.
The "RD" designation stands for Red, which tells you the copper surface still retains its bright, original color.
Billions of Lincoln cents left the presses during the 1980s for everyday pocket change.
Most of them picked up scratches and stains from circulation very quickly.
Finding an example that survived without normal handling marks is what makes this modern issue notable to collectors.
A standout example of the 1986-D RD cent set an auction record through EA.
The coin was certified at a near-flawless grade of 69.
On the standard 70-point coin grading scale, a 69 is essentially perfect to the naked eye.
Only microscopic imperfections keep a coin at this level from reaching the absolute maximum grade.
The sale realized a notable 12/21 record price in the EA auction.
Standard pocket change pennies from 1986 are only worth their face value.
Collectors pay top dollar for certified pieces because finding a coin with zero surface contact marks is remarkably difficult.
This high price comes down entirely to condition rarity.
Even though the Denver Mint struck massive quantities of these pennies, the striking process was fast and rough.
New coins dropped into giant metal bins right off the dies, creating tiny nicks before they ever left the mint.
Modern copper-plated zinc planchets are also prone to spotting, oxidation, and surface bubbling over time.
Most preserved coins from 1986 top out at lower Mint State grades like 65 or 66.
Competition heats up among registry set collectors whenever a piece earns an elite 69 grade.
These specialized collectors want the highest-graded example in existence for every single date and mint mark.
That strong collector demand at the very top of the grading scale pushes record auction bids far above normal market levels.
You can start checking your own coins by examining the date and the mint mark first.
Look for the 1986 date on the right side of Lincoln's chest with a small "D" directly underneath it.
Use a 5x or 10x jeweler's loupe to inspect the surfaces under good lighting.
Check the highest points of Lincoln's cheek, jaw, and hair for any signs of wear or dullness.
Inspect the fields of the coin for tiny scratches, zinc rot, or dark carbon spots.
To qualify for a top grade, the coin must show strong luster and full, bright red copper color with no brown toning.

Keep in mind that normal circulated 1986-D pennies are extremely common and only worth one cent.
Only an uncirculated piece in exceptional, certified condition will match the standard of this record-holding coin.
