Did you know that some of the world’s most precious and rare coins remain in circulation to this day? What may be an ordinary coin in your purse or piggy bank may be worth millions. These odd coins are extremely valuable since they possess minting errors, historical significance, or exclusive metal composition. Some of these coins have even been auctioned off for as much as $300,000. For coin collectors, numismatists, and even hobby collectors, to come across such a coin is finding treasure. Here are some of these valuable and rare coins.
1. 1955 Doubled Die Lincoln Cent
This coin is famous for its unique mint error. The date and words like “Liberty” and “In God We Trust” are doubled on the front side. The mistake occurred during minting coins, and only a few of these coins were circulated. This coin can command a price of as much as $300,000 if in good condition.
2. 1937-D Three-Legged Buffalo Nickel
This is a rare coin famous for its uncommon minting error, in which one of the buffalo’s front legs is absent because the die was over-polished. This error makes the coin extremely collectible. This coin can sell for six-figure prices when it is in good condition. It is a collector’s dream coin.
3. 1964 SMS Kennedy Half Dollar
One of the rarest coins is one of which so few exist and of which such little is known. SMS coins were produced via a unique method that causes them to look peculiar. This limited half dollar coin can sell for more than $300,000 if discovered in mint condition when there are less than a dozen authenticated pieces in existence.
4. 1999-P Wide “AM” Lincoln Cent
This coin has a rare error in which the letters “A” and “M” of “America” on the back are more distanced than normal. Few of these coins were produced in Philadelphia during 1999, and therefore they are extremely rare. These coins are worth thousands of dollars depending on the grade, with the finest pieces selling for six figures.
5. 1976 Bicentennial Silver Proof Quarter
While the majority of 1976 Bicentennial Quarters are ordinary, a few were minted in silver for collectors. Every now and then, these coins make their way into circulation. When a quarter is silver rather than the standard copper-nickel alloy and is in good condition, it is worth a considerable sum. A few of these rare silver quarters have sold for more than $300,000.
