The 1923 Lincoln cent was struck at the main United States Mint in Philadelphia.
Like other pennies from that era, it was made from a standard copper alloy.
You can tell it came from Philadelphia because there is no mint mark below the date.
Over the decades, most early Lincoln cents were spent in daily commerce and turned brown from handling.
Finding a penny from this year that still looks brand new is very difficult.
That makes high-grade survivors stand out clearly to serious collectors of the series.
An exceptional example of this coin brought a top price of $24,000 at Heritage Auctions.
The coin was certified in Mint State Red condition by a major grading service.
Mint State means the penny never circulated and shows no wear on its high points.
The Red designation means the copper kept almost all of its original bright factory color.
Serious bidders competed hard for this piece because certified examples at this quality level rarely appear.
Top prices like this happen only when independent grading services confirm the surfaces are pristine.
Copper is a very active metal that reacts quickly with air, moisture, and skin oils.
Most 1923 pennies turned into dark brown coins within a few years of release.
Others developed spots, stains, or faded into a reddish-brown shade.
A full-red surface on a 1923 Philadelphia cent is an extreme condition rarity.
Collectors who build complete sets of Lincoln cents need bright red examples for top registry rankings.
Because so few flawless red coins survived, demand far outpaces the available supply.
This strong collector competition pushes prices for top-tier coins into five figures.
Start by checking the date on the right side of Lincoln's bust.
Look for the numbers 1923 clearly stamped on the surface.
Check the space directly beneath the date to make sure there is no mint mark letter.
Examine the overall color of the copper under a good desk lamp.
A standard circulated coin will look brown, while a valuable piece will glow with original orange-red copper luster.
Use a 5x or 10x magnifying glass to look for scratches, wear on Lincoln's cheek, or dark spots.
If you want a quick first look, you can scan the coin with the CoinKnow app to get an idea of its grade and variety.
