Legendary tales from numismatic history - rare finds, famous collectors, and coins that made headlines.
The Mystery: This is one of the most famous coins in the world, yet it's a total lie — no silver dollars were actually made in 1804. The Mint had stopped making them in 1803 because silver was getting too expensive.
The Diplomatic Gift: Thirty years later, in 1834, President Andrew Jackson wanted to give "complete" sets of U.S. coins as fancy gifts to foreign leaders like the Sultan of Muscat and the King of Siam. Since 1804 was the last year they were recorded as being made, the Mint just struck a few new ones with the old 1804 date.
The Rarity: Only 15 of these coins are known to exist. One specimen, named the "Dexter" dollar, sold for over $7.6 million in 2021.
The Oops: In 1883, the Mint released a new "Liberty Head" nickel with a large Roman numeral V on the back — but they forgot to include the word "CENTS."
The Scam: Enter Josh Tatum, a deaf-mute man who noticed the nickel was almost the same size as a $5 gold piece. He allegedly gold-plated thousands of them and bought 5-cent cigars — merchants, assuming it was gold, would give him $4.95 in change!
The Legend: When Tatum was caught, he was acquitted because he never actually said the coins were worth $5. Some have cited this as the origin of the term "joshing" (meaning to joke around), though language historians note the word appeared in print before this incident — making the connection colorful folklore. Either way, the Mint rushed to add "CENTS" just months later!
The Mystery: In 1913, the Mint officially switched to the "Buffalo" design, yet five Liberty Head nickels were mysteriously struck with a 1913 date. No one knows for sure who made them — suspicion falls on Samuel Brown, a Mint employee who later "discovered" them and displayed the full set in 1920.
The Tragedy: One specimen was owned by George Walton, who was killed in a car crash in 1962 with the coin in his pocket. His heirs were told it was a fake, so it sat in a closet for 30 years before experts authenticated it as a multi-million dollar treasure in 2003.
The Fame: These five coins are among the most valuable in the world, with one selling for $4.56 million at Heritage Auctions in 2010, and another at $3.7 million in 2007 — all five are considered priceless. One specimen even appeared on the TV show Hawaii Five-O!
The Gold Rush: After gold was discovered in California in 1848, the U.S. needed a bigger coin. In 1849, Congress authorized a massive $20 "Double Eagle" coin.
The Only One: While the Mint made hundreds of thousands in 1850, only one gold specimen was struck with the 1849 date — a trial piece to show off the new design.
The Price Tag: In the early 1900s, J.P. Morgan reportedly offered $25,000 for it (a massive fortune then), but was turned down. It now lives in the Smithsonian Institution and is considered priceless.
The Audit: Only 24 Barber dimes were struck in San Francisco in 1894 — believed to have been made just to balance a tiny $2.40 discrepancy in the Mint's ledgers.
The Treat: Legend says Mint Superintendent John Daggett gave three dimes to his daughter Hallie, telling her to save them. Instead, she immediately spent one to buy a dish of ice cream! Today, only nine of the 24 are known to exist — if you find one, it could be worth over $1.9 million.
The Mistake: In 1937, a rookie worker at the Denver Mint named Mr. Young was trying to fix a damaged metal-stamping die. He polished it so aggressively to remove scratches that he accidentally ground off the buffalo's front right leg! The Mint didn't notice, and thousands were released into circulation.
The Hunt: Collectors today look for this error by checking if the buffalo's leg is missing while the hoof remains visible. Authentic ones often have a "mushy" look on the back because the die was polished so thin.
The Armor Cover-Up: The 1916 Standing Liberty quarter caused a stir because Lady Liberty was depicted with an exposed breast. By 1917, the Mint quickly redesigned the coin, giving her a vest of chainmail armor. The original "Type 1" version is now a rare collector's item.
The Broken Sword: The 1921 Peace Dollar was designed to celebrate the end of World War I. The original design showed an eagle breaking a sword to symbolize the destruction of war tools. However, the public thought it looked like a symbol of defeat — the Mint's chief engraver had to manually grind the sword off the dies just days before production began!
The Gossip: When the first Lincoln penny was born in 1909, designer Victor David Brenner placed his initials V.D.B. prominently on the back.
The Outcry: People were furious, calling it "illegal advertising" for the artist. The Mint stopped production after just nine days to remove the letters — creating the legendary 1909-S VDB penny, the "Holy Grail" for penny collectors.
The Return: The initials didn't return until 1918, when they were hidden in a tiny spot on Lincoln's shoulder — where they remain to this day.
1943 "Steelies": Copper was precious for bullets, so the Mint made pennies out of zinc-coated steel for one year. They look silver and stick to magnets!
The Million Dollar Error: By mistake, a few copper blanks from 1942 were left in the machines. Only about 40 genuine 1943 copper pennies exist — they can sell for over $1.7 million.
The Reverse Error: In 1944, the Mint went back to copper, but a few 1943 steel blanks were accidentally used — creating a rare silver-colored 1944 error worth a small fortune.
The Ban: During the Great Depression, President Roosevelt banned people from owning gold and ordered all 1933 $20 gold coins melted into bars.
The Escape: About 20 coins were stolen from the Mint. One found its way to King Farouk of Egypt. After decades in hiding, that single coin was eventually made legal by the U.S. government.
The Record: It sold at auction in 2021 for $18.9 million — the most ever paid for a coin in history.
The "Cheerios" Dollar (2000): General Mills put 5,500 new Sacagawea dollars in boxes of Cheerios. Years later, collectors found these were actually prototype coins with much more detail in the eagle's tail feathers. They are now worth thousands of dollars!
"Godless" Dollars (2007): Some George Washington dollar coins missed the step where "In God We Trust" was printed on the edge. Smooth-edged versions became known as "Godless Dollars."
"In God We Rust" (2005): On some Kansas state quarters, grease clogged the letter 'T' in the word "Trust," making it look like the coin was warning you about rust!
The Change: 1982 was the year the penny changed from 95% copper to zinc with a thin copper skin. Because the Mint also changed the size of the date mid-year, there are seven common versions of the 1982 penny.
The Holy Grail: Collectors hunt for the 1982-D Small Date Copper. It technically shouldn't exist because Denver was supposed to be all-zinc by the time that design was used. Only two have ever been found!
The Accident: Due to a misalignment during the die-making process, the date and lettering on some 1955 Lincoln cents were hubbed twice at a slight offset. The result? Bold, unmistakable doubling visible to the naked eye — you can clearly see a ghostly second "1955" right next to the first.
The Escape: An estimated 24,000 error cents were mixed with normal coins and released into circulation before anyone caught the mistake. Vending machine companies noticed first — the coins were jamming their machines because the raised doubling threw off the weight sensors.
The Hunt: Today a nice example trades for $1,500–$15,000 depending on grade. It's the single most sought-after Lincoln cent error — and proof that sometimes the Mint's biggest mistakes become collectors' greatest treasures.
The Crisis: When the Civil War broke out in 1861, the New Orleans Mint fell under Confederate control. Officials quickly designed their own coin featuring the Confederate shield and a goddess of Liberty — and struck exactly four of them as presentation pieces.
The Secret: The die used to make those four coins was shipped to New Orleans physician Dr. B.F. Taylor, who secretly kept it for over a decade. In 1879, he and a partner used the original die to produce about 500 "restrikes" — now called the "Taylor restrikes" — to sell to collectors. They used regular 1861-O US half dollars as blanks, scraping off one side and re-striking it with the Confederate design.
Today: The four original strikes are each worth over $1 million. The 1879 restrikes sell for $10,000–$50,000. The original Confederate die itself resides at the American Numismatic Society in New York.
The Problem: By 1974, the price of copper had risen so high that the government seriously considered replacing the Lincoln cent with a pure aluminum version. The Mint struck approximately 1.57 million aluminum test cents — and distributed about 14 to Congressional members and staff for evaluation.
The Recall: Congress ultimately rejected the change and the Mint ordered all test coins returned and melted. All 14 distributed samples were supposed to be handed back — but at least one wasn't. For decades, a rumored "Congressional cent" floated around the collector community. In 2014, a former congressional aide's estate produced one.
The Legal Twist: The US government claimed ownership and it was forfeited — because technically, all 1974-D aluminum cents remain government property. If one ever turns up in your change jar, you're legally required to return it. (But it would also be worth a small fortune before you did!)
The Impossible Coin: A "mule" coin is struck with mismatched dies — like pressing a coin with the wrong front or back. In the year 2000, someone at the Philadelphia Mint accidentally mated a Washington State Quarter obverse die with a Sacagawea dollar reverse die. The result was a coin the size of a quarter with Washington's portrait on one side and an eagle on the other — in gold color.
The Discovery: An Arkansas collector named Frank Wallis found the first one in a bag of Sacagawea dollars he bought at his bank. He thought it was a novelty, then had it authenticated. The numismatic world was stunned — the Mint denied it was possible at first.
Today: About 18–19 examples are known to exist. The finest ones have sold for over $150,000. It remains one of the most spectacular mint errors in US history.
The Magnet Test: If a 1943 penny sticks to a magnet, it's a common steel coin. If it doesn't, it might be the million-dollar copper error!
The Weight Test: Use a digital scale. A 1982 copper penny weighs 3.1 grams, but the new zinc ones only weigh 2.5 grams.
The Tail Feathers: Look closely at your 2000 Sacagawea dollars. If the tail feathers have diagonal lines and are very detailed, you found a "Cheerios" treasure!
