The world of rare coins is filled with incredible treasures, some of which are worth millions of dollars.
While you might think that coins of such high value would be locked away in museums or private collections, some rare dimes and Bicentennial quarters worth $15 million each are still circulating among us.
These coins are often overlooked by the casual observer, but for the knowledgeable collector, they are a once-in-a-lifetime find.
1. 1943 Mercury Dime (Silver Error Coin): $15 Million
The 1943 Mercury Dime is famous for its silver composition. Due to the World War II metal shortages, the U.S. Mint shifted production of some coins to alternative metals.
While most Mercury dimes from that year were struck in copper, a few were mistakenly struck in silver, creating one of the most significant minting errors in U.S. coinage history.
Why is it valuable?
The 1943 Silver Mercury Dime is extremely valuable due to its error in composition. Only a handful of these silver dimes were produced by mistake, and they are considered highly collectible.
The rarity and error make them worth $15 million when found in excellent condition. Many of these coins were melted down or lost, and only a few remain in circulation today.
2. 1916-D Mercury Dime: $15 Million
The 1916-D Mercury Dime is one of the most famous and valuable dimes ever minted. It was produced in Denver with a low mintage of only 264,000 coins, making it one of the rarest coins in the Mercury Dime series.
This coin is highly sought after by collectors, and in mint condition, it can easily fetch $15 million at auction.
Why is it valuable?
The 1916-D Mercury Dime is rare because of its low mintage and the fact that most of the coins were worn down or lost over the years. Because so few were made, and fewer still are in pristine condition, it is considered one of the holy grails of U.S. coin collecting.
The value is also boosted by the fact that it is part of the Mercury Dime series, which is highly collectible among numismatists.
3. 1942/1 Mercury Dime (Overdate Error): $15 Million
The 1942/1 Mercury Dime is another incredibly rare and valuable coin due to a minting error. This overdate error occurs when a 1941 die was used to strike coins intended to be from 1942.
The result was that the “1” from the 1941 die appears next to the “2” in “1942,” creating a distinctive and highly collectible coin.
Why is it valuable?
The 1942/1 Mercury Dime is valuable because of its error, which makes it one of the most famous error coins in U.S. history. Only a small number of these overdated dimes have been discovered, and they are extremely sought after by collectors.
Coins with minting errors, especially ones that are this rare, tend to command prices well into the millions, with $15 million being a typical auction price for a well-preserved example.
4. 1976 Bicentennial Quarter: $15 Million
The 1976 Bicentennial Quarter was minted to commemorate the 200th anniversary of the United States. The coin features a unique design with the drum, 13 stars, and Liberty Bell on the reverse side, symbolizing the nation’s independence.
While most of these coins are worth only their face value, a small number were struck with minting errors, and these can be worth as much as $15 million.
Why is it valuable?
The 1976 Bicentennial Quarter can fetch millions when it has significant minting errors like misaligned dies, double strikes, or off-center designs. These errors make the coin a rarity and very valuable to collectors.
Due to its popularity as a commemorative coin, finding one of these error quarters can lead to a huge windfall, as they are highly prized for their historical significance and rarity.
