Spot $800K Pennies: 3 Key Markings to Check Before Cashing In

The recent auction of specially minted pennies has generated significant interest, highlighting their potential value. These unique coins, which were among the last produced prior to the discontinuation of the penny, fetched an astonishing total of $16.76 million at a California auction organized by the U.S. Mint. This event set a record for the highest auction value of special coins on behalf of the Mint, according to Stack’s Bowers Galleries.

Significant Auction Details

The auction featured several 232 three-coin sets, each containing a 2025-D penny from the Denver Mint. Additionally, each set included a 2025 penny and a historic version struck in 24-karat gold from the Philadelphia Mint. During a four-hour bidding session, the average price for each set reached approximately $72,000. Remarkably, 17 individual lots sold for over $100,000, with Set #232 achieving a staggering $800,000.

Identifying Valuable Pennies

For collectors and casual finders alike, knowing how to identify valuable pennies is crucial. Here are three essential guidelines to check before cashing in on your coins:

• The 2025 “Omega” Scan: Look for a tiny “Ω” symbol behind Lincoln’s shoulder on pennies from 2025. This marks them as part of the exclusive “Omega” class.
• The “S” Hunt: Pennies with an “S” denote they were minted in San Francisco. While not all are exceedingly rare, specific key dates, like the 1931 penny, can be quite valuable. One sold for $18,600 in 2021.
• The Magnet Test: Use a refrigerator magnet to determine the material of a 1943 penny. If it sticks, the penny is made of common steel, worth only 10 cents. If it does not stick, it is copper and may be worth up to $100,000. Conversely, if a 1944 penny sticks, it may be a rare steel error, with some selling for over $408,000.

Background on Penny Discontinuation

The recent attention on rare pennies coincides with a moratorium on penny production established by the U.S. Mint following directives from former President Donald Trump. He highlighted the rising costs of producing pennies, which had begun to exceed their face value.

Understanding these markers can significantly impact how much your pennies might be worth. Whether you’re a collector or just checking your change jar, you may be sitting on a small fortune.
