The San Francisco Mint struck this Lincoln penny back in 1919.
It is made of standard bronze, which gives fresh cents a bright copper tone.
World War I had just ended, and commerce across the country was booming.
Millions of cents left the mint to meet daily shopping needs on the West Coast.
Most of these pennies went straight into pockets, registers, and piggy banks.
Very few people thought to save brand-new pennies directly from the mint back then.
Because of that, finding a 1919 penny from San Francisco with its original color is tough today.
It stands out in the Lincoln cent series as a major condition rarity.
One extraordinary example crossed the auction block at Heritage Auctions.
The winning bidder paid $43,200 to take it home.
Professional grading services evaluated this piece as an MS Red coin.
The "MS" stands for Mint State, meaning the coin never saw a day of active circulation.
The "Red" label means it still has nearly all of its original, fiery copper luster.
Copper naturally tarnishes, darkens, and turns brown over decades of exposure to air.
Holding onto that bright red glow for over a century is exceptionally rare for early branch mint pennies.
Collectors at the top level are willing to pay massive sums for that level of preservation.
Keep in mind that typical pocket change finds will not sell for figures like this.
The main driver behind this high value is condition rarity.
A coin can have a large original mintage and still be scarce in top grades.
San Francisco struck plenty of pennies in 1919, but almost all of them wore down in circulation.
Even among uncirculated pieces, most turned brown or developed dark spots over time.
A 1919-S in full-red condition is an extreme outlier.
Lincoln cents are also one of the most widely collected coin series in the world.
Thousands of collectors compete to build high-grade registry sets.
When an elite Mint State red coin appears, serious buyers push the bids very high.
Without the full red designation, the market value drops dramatically.
You can inspect your own coin with a few simple steps.
Start by grabbing a 5x or 10x magnifying glass and sitting under a bright desk lamp.
Look closely at the date on the right side of Lincoln's portrait.
Check right below the "1919" date for a tiny "S" mint mark.
If there is no letter below the date, the coin was struck in Philadelphia instead of San Francisco.
If you see a "D", it was made in Denver.
Next, examine the overall surface color of the penny.
To qualify as full red, the metal must show bright copper color across both sides without heavy brown toning.
You can use Coin Value Checker on your phone to get a quick first impression of your coin.
Be careful not to confuse a genuine red cent with an old brown coin that someone cleaned with harsh chemicals.
Cleaned coins have a dull, unnatural pink look and lack original mint luster.
If you suspect you have an authentic uncirculated red coin, consider sending it to a third-party grading service.
