The 1971 Lincoln Cent is a standard modern coin that most people see in pocket change.
Billions of these pennies were struck during the regular production run in 1971.
A major error occurred during the die preparation process for a tiny batch of these coins.
The working hub impressed the design onto a working die at slightly different angles during multiple hubbing steps.
This misalignment created a clear doubled image directly on the steel die.
Coins struck with this die carried that doubled image directly onto their surfaces.
Today, this distinct variety is officially cataloged in major reference guides as FS-101.
It stands out as one of the most prominent doubled die varieties in the entire modern Lincoln Cent series.
Top-tier examples of this variety command strong interest whenever they cross the auction block.
One exceptional specimen reached a record price level through Stack's Bowers Galleries.
The coin was certified and graded in Mint State 66 condition.
A grade of 66 means the coin has practically no noticeable surface flaws or bag marks from the minting process.
It retains full original mint luster and displays crisp, sharp design details across both sides.
Coins from the early 1970s rarely survive in such clean condition because most went straight into active circulation.
Professional certification gives buyers confidence that the coin is genuine and accurately graded.
That high level of preservation explains why top certified examples attract serious bids from advanced collectors.
The primary driver of value for this penny is the dramatic nature of its doubled die obverse.
Most coin varieties feature minor hub doubling that requires high-power lab equipment to spot.
The 1971 FS-101 features strong spread across several major design elements on the front of the coin.
Condition rarity also plays a massive role in setting its value.
While worn examples show up occasionally, fully uncirculated pieces are scarce.
Copper coins from this era easily develop spots, tarnish, or surface corrosion over time.
Finding a piece that avoided both circulation damage and environmental aging is difficult.
Collector demand for famous doubled die pennies remains consistently high year after year.
When high demand meets an extremely small supply of pristine coins, values rise accordingly.
You need a quality jeweler loupe or a pocket microscope with at least 5x to 10x magnification to check your coin.
Focus your attention directly on the obverse lettering and numerals.
Look closely at the motto IN GOD WE TRUST along the upper rim.
The letters will show distinct secondary images and clear separation on their outer edges.
Next, examine the word LIBERTY on the left side of Lincoln portrait.
You should see clear doubling on the vertical and horizontal bars of the letters.
Check the date 1971 on the lower right field as well.
The digits display strong doubling toward the south and west.
Do not confuse true hub doubling with common strike doubling or mechanical doubling.
Strike doubling looks flat and shelf-like, whereas a true doubled die shows rounded, raised letter forms.
