The Denver Mint struck the 2010-D Lincoln cent during a major turning point for American pocket change.
This penny introduced the Union Shield design on the reverse side.
The new reverse replaced the long-running Lincoln Memorial design that collectors knew for decades.
The United States Mint created this new look to represent the preservation of the United States as a single country.
The Denver Mint struck these coins using a core of zinc covered by a thin copper plating.
Because of this modern composition, each piece weighs about 2.5 grams.
Coins with the RD designation keep their full, original red copper luster without fading into brown.
As the very first Denver issue to carry the shield design, this coin holds a special place in the Lincoln cent series.
A pristine example of the 2010-D Shield cent brought an eye-catching price at public auction.
Heritage Auctions handled the sale of this standout piece in April 2013.
When the bidding ended, the coin sold for $4,994.
The coin earned an official grade of MS-67 Red from professional evaluators.
An MS-67 grade means the coin has an exceptionally clean strike with almost no contact marks or visual flaws.
The Red label confirms that the surfaces still show their original, bright mint glow.
Prices like this belong strictly to top-tier certified specimens, not to normal coins pulled from pocket change.
Modern pennies are made in huge numbers, but finding one in flawless condition is very difficult.
Zinc-based pennies react quickly to moisture and air, which makes pristine preservation rare.
Most 2010 pennies picked up tiny scuffs, spots, or scratches during the high-speed minting and packaging process.
Because 2010 marks the first year of the Shield reverse, many type collectors wanted the best possible piece for their sets.
This strong demand from type collectors met an extremely low supply of near-perfect coins.
That exact mix of first-year status and condition rarity drove the high auction result.
You can check your own coins at home by looking closely at a few specific details.
First, check the front of the penny directly beneath the 2010 date for the small D mint mark.
Turn the coin over to make sure it features the Union Shield design with thirteen vertical stripes.
Use a 5x or 10x magnifying glass to inspect the smooth fields of the coin under good light.
Look for tiny carbon spots, contact dings, or dull gray areas where the zinc core might show through the plating.
To qualify for the Red label, the coin must show full, bright copper color across both sides without dark toning.
