The United States Mint struck this Lincoln penny back in 1973.
It is part of the long-running Lincoln Memorial cent series that collectors know well.
Pennies from this era were made from a traditional bronze alloy rather than modern zinc.
Billions of these coins entered daily circulation across the country over the years.
Most of them picked up heavy wear, fingerprints, and dark toning from regular use.
Finding a vintage memorial cent that retains its original mint color is quite tough.
The RD designation stands for Red, meaning the coin kept its bright copper shine.
This specific coin ranks at number 74 on the top 200 list of valuable pennies.
An exceptional example of this coin caught serious attention on the auction block.
The sale took place through the auction house EA.
Bidders competed until the hammer fell at an auction record of 2/22.
Professional grading services certified the coin at a lofty grade of 67 RD.
A grade of 67 represents a near-perfect strike with almost no visible flaws.
Only a tiny fraction of vintage bronze pennies ever achieve such a high technical grade.
Top-tier registry set builders pay top dollar to secure coins in this elite tier.
A certified piece guarantees that the original red luster is genuine and well-preserved.
Everyday pocket change from the 1970s rarely survives in untouched collector condition.
Bronze is a reactive metal that tarnishes very quickly when exposed to air and moisture.
Most 1973 pennies turned brown or red-brown within a few years of release.
This creates an extreme condition rarity for pieces that stayed fully red.
Collector demand remains strong for high-grade Lincoln Memorial cents.
Many numismatists try to build complete date runs with matching red surfaces.
When few pristine specimens exist, competition between serious collectors drives the price up.
Standard circulated copies do not carry these high premiums because millions still exist.
The value lives entirely in the rare combination of sharp details and pristine color.
You can inspect your own 1973 pennies at home using a few basic tools.
Grab a good magnifying glass or a ten-power jeweler loupe to check the coin.
Look closely at Lincoln's cheek, jawline, and coat for any signs of friction or wear.
Turn the coin over and check the steps and pillars of the Lincoln Memorial on the back.
Examine the overall color to see if it shows full copper red across both sides.
If the surface shows dark spots, brown patches, or dull metal, it will not grade at the top level.
Make sure you do not confuse normal brown pocket change with a certified mint-state specimen.
If you want a fast way to check your change, you can scan the piece with Coin Value Checker to see where it stands.
Always hold collectible coins by their outer edges so your skin oils do not damage the surface.
Never clean or polish an old penny because harsh chemicals destroy the original mint luster.
Only professional grading can confirm if your coin truly meets the strict standard of a top-grade red cent.
