The 1918-S Lincoln cent came out of the San Francisco Mint during the final year of World War I.
It belongs to the classic Lincoln cent series, which first started back in 1909 to honor Abraham Lincoln.
Like other pennies of its time, this piece was made using a traditional bronze alloy.
San Francisco struck millions of pennies in 1918, but finding one today in its original state is a different story.
Most of these pennies entered circulation right away to keep up with wartime commerce.
Decades of handling left the vast majority worn, scratched, or heavily oxidized.
The "RD" label stands for Red, meaning the coin still shows the bright copper color it had when it left the dies.
Full Red examples from the San Francisco branch are notoriously tough to find for this year.
This particular coin made waves when it crossed the auction block through BM.
The recorded sale for this piece reached an impressive 8/07 mark.
Professional coin graders certified the penny at an extraordinary Mint State 65 Red.
A grade of MS65 means the coin is an exceptional uncirculated specimen with very few contact marks.
The surfaces retain their full, glowing original red luster without the brown toning typical of old bronze.
High-end sales like this show how much serious buyers will pay for top-quality San Francisco copper.
Keep in mind that standard, worn coins from this year will not sell anywhere near this level.
Condition rarity is the main reason this coin commands such strong prices.
Early branch mint cents from San Francisco often suffered from weak strikes and poor metal quality.
Finding a 1918-S with sharp details is already hard on its own.
Bronze reacts quickly to moisture, air, and human touch over time.
Because of this, most surviving 1918 pennies have turned brown or developed dark spots.
A specimen that stays fully red after more than a century is an extreme outlier.
Lincoln cent enthusiasts actively compete for top-graded pieces to complete registry sets.
When high collector demand meets a tiny pool of surviving gem-quality coins, prices climb rapidly.
You can start by looking at the front of the coin right below the date.
You want to spot a small "S" mintmark under the numbers "1918".
If there is no letter beneath the date, the penny was made in Philadelphia instead.
Grab a magnifying glass with at least 5x magnification to inspect the surfaces closely.
Check the highest points of Lincoln's cheek, jaw, and hair for any signs of friction or wear.
Flip the coin over and check the tips of the wheat stalks on the reverse.
Pay close attention to the surface color under a good desk lamp.
To qualify as Red, the coin must show nearly all of its original mint luster rather than a dull brown tone.
