TikToker professorpenny explained why some 1969 pennies are worth $15,000

On social media, a COIN collector offered tips on where to look for a particularly valuable circulated penny.

A video was posted by professorpenny, a TikTok user, explaining the specific error that makes some cents from 1969 worth thousands of dollars.

Professor Penny advised that you can probably sell one of these 1969-S error pennies for $15,000 because they are so scarce.

This 1969 coin is among the most well-known and sought-after doubled die errors.

Typically, coins are struck several times by coin dies, the metal objects used to imprint emblems on coins.

Some coins have misaligned die strikes that make the letters, numbers, and images appear to have been stamped twice in slightly different locations.

If the doubling appears on the heads or tails side, respectively, doubled die coins are either categorized as obverse or reverse.

The numbers and letters on the obverse side of some 1969-S pennies were doubled, and the errors are visible to the unaided eye.

On these error coins, the words "Liberty" and "In God We Trust," as well as the 1969 mintmark to Lincoln's right, will be doubled.

You could make at least $10,000 if you can locate one of these mistaken pennies and sell it at auction.

Approximately $15,000 is the typical value of a circulated 1969-S doubled die cent, according to the Professional Coin Grading Service.

The price of the coin can be much higher when it is uncirculated, with an average selling price of about $35,000.

The highest price ever paid by a collector for a 1969-S cent was $48,875 in 2008 for a coin in perfect condition.
