US Mint Ends Penny Production With a $16 Million Auction

On December 11th, Stack’s Bowers Galleries auctioned off 232 special three-coin sets on behalf of the U.S. Mint, each containing the last pennies ever struck for circulation. These weren’t your pocket change pennies. Each coin bore a small Ω (Omega) privy mark, the final letter of the Greek alphabet, marking them as the official capstone to a 232-year run that started with the Chain Cent back in 1793.

The sets included a 2025 penny from the Philadelphia Mint, a 2025-D from Denver, and something that’s never existed before: a 24-karat gold penny, also struck in Philadelphia. Only 232 sets were made, one for each year the penny was in production. The number wasn’t random. It was the U.S. Mint’s way of commemorating two centuries of the one-cent coin before pulling the plug on production.

Trump ordered the halt back in February as part of broader cost-cutting measures. The final pennies were struck at the Philadelphia Mint in November, and instead of entering circulation like every other penny for the past two centuries, these went straight to auction.

The bidding started slightly late because collector interest was so intense it delayed the proceedings. When things finally got rolling, it became clear this wasn’t going to be a typical numismatic auction. Set #1 immediately jumped to $200,000, setting the tone for what Stack’s Bowers President Brian Kendrella called a “landmark offering.”

The auction stretched nearly four hours with competitive bidding throughout. Seventeen sets topped $100,000, and the lowest-priced lot still went for $48,000. Not bad for what would’ve been three cents in face value if these had actually circulated.

The crown jewel was Set #232, the absolute last one offered. It contained the very last circulating pennies struck at both Philadelphia and Denver, the final gold Omega penny, and the three sets of canceled dies used to strike the entire series. That lot hit $800,000, making it the most valuable modern U.S. numismatic item ever sold. It beat the previous record of $550,000 set earlier in 2025 by Stack’s Bowers when they sold Space Flown 24-karat Gold Sacagawea dollars.

Here’s the math that should make your head spin. The total gold melt value of all 232 sets combined was around $210,000 at the time of sale. The auction brought in $16.76 million. That’s roughly 80 times the metal value, which tells you everything about what collectors were actually buying: history, exclusivity, and the end of something that’s been part of American life since before most states existed.

The 24-karat gold penny alone is unprecedented. The U.S. Mint has never officially struck a cent in gold before. These Omega pennies have the lowest mintage in the entire Lincoln penny series and are among the rarest coins in the penny denomination spanning back to 1793. The mintage is more than 2,000 times lower than the famous 1909-S V.D.B. Lincoln penny that collectors obsess over.

For context, Stack’s Bowers has been selected by the U.S. Mint for special auctions five times now. Their previous biggest sale was the 1933 Saint-Gaudens double eagle for $7.5 million back in 2002. This Omega penny auction doubled that, making it the U.S. Mint’s most valuable special coin auction ever.

We’ve been all over the penny’s discontinuation, recognizing from the earliest announcement that they’d be worth significantly more than their face value once production finally ceased. In February, resellers were already flipping 50-coin rolls for up to $50 at a time, and we even tracked a limited run of Topps cards sold to commemorate the coin.

The Omega sets were never meant for regular collectors. Stack’s Bowers waived buyer’s premiums to keep costs down, but when bidding starts at $3,500 per set and the cheapest one still sells for $48,000, you’re looking at a market for ultra-high-net-worth individuals and institutional collectors only.

For the thousands of collectors actively assembling Lincoln penny sets, only 232 will ever achieve “true completion” with these Omega marks. Everyone else is stuck with a nearly complete set missing the official finale.

If you grabbed regular 2025 pennies hoping they’d appreciate because of the discontinuation, this auction doesn’t really change your situation. The Omega privy mark is what made these valuable, not the year or the fact that penny production ended. Your regular 2025-P or 2025-D pennies are still just regular pennies that happen to be from the final production year.

The secondary market for standard 2025 pennies has largely settled. They’re worth slightly more than face value to completionist collectors, but we’re talking dollars, not thousands. The Omega sets exist in their own stratosphere.

This auction serves as a fitting bookend to America’s penny story. What started in 1793 with the Chain Cent ended in 2025 with wealthy collectors bidding $800,000 for the privilege of owning the absolute last ones struck. In between, the penny went from being essential currency to something people literally throw away or leave in tip jars.

The irony isn’t lost on anyone. The coin deemed too expensive to keep producing just generated nearly $17 million for the U.S. Treasury through its final auction. Trump’s “rip the waste out” cost-cutting measure turned into one of the most profitable numismatic events in American history.

For serious collectors, this auction is a disappointment. Many were hoping that they’d get a chance to hunt for an Omega mark in the wild and add it to their own collection. Unless you’ve got tens of thousands of dollars to spend on your hobby, these pennies are unobtainable.
