But if you stumble across the right one, it could earn you thousands. The 1909 S Lincoln Wheat Cent with a V.D.B initial is one such penny. “The variety of this coin had a very low production,” says Rob Eisenstein of collector’s store Cardboard and Coins. “Additionally, this rare variety has the initials of the Lincoln Cent design creator, V.DB., on the reverse of the coin at the bottom.“ae0fcc31ae342fd3a1346ebb1f342fcb To identify the coin, start by looking for the year 1909. Then, look for the letter “s” under the year. Finally, see if you can locate the initials V.D.B on the bottom of the tail side. If you can, you might be sitting on a pile of cash. Don’t believe you’ll find one? Think again. Despite the relatively low mintage of this coin, there were still 484,000 created, according to coin collecting site USA Coin Book. The pennies are worth $940 on average and $2,000 and up for coins in mint condition. Yes, there is more than one type of valuable penny. The 1955 Lincoln Wheat Cent, Doubled-Die Obverse penny is worth around $800 in average condition and $4,000-plus in mint condition. So, what makes this coin special? “There was an error at the mint, with the resulting coins displaying what looks like a 1955 over a 1955,” says Eisenstein. “The date—among other features on the front and obverse—is seemingly doubled.” Indeed, the penny looks like you’re staring at it with double vision. This interesting defect is highly valuable to collectors. RELATED: For more money advice delivered straight to your inbox, sign up for our daily newsletter. If you’re not blessed with the good fortune to find a penny that’s worth a grand, don’t fret. There are many common coins that have more value than you might think. “Circulated, or worn, 90 percent silver dimes, quarters, and half dollars—which were made from 1964 and earlier—are currently worth over 20 times face value,” says Michael Fuljenz, a member of the non-profit organization Professional Numismatists Guild. Fuljenz notes that a silver half dollar is worth at least $10, while a pre-1965 dime is worth at least $2. “Silver dollars made from 1935 or earlier are often worth at least $30 or more depending on their condition and date of issue,” says Fuljenz. “Rare date and mintmark silver dollars in excellent condition can be worth hundreds and even thousands of dollars. But even common silver dollars are valuable because silver has risen to about $25 an ounce, and there is some collector value.” Let’s say you’re clearing out your change purse and think you may have stumbled upon a valuable coin. Now what? First, “do not clean the coin,” says Donn Pearlman, an affiliate member of the Professional Numismatists Guild. “Improper, harsh, abrasive cleaning can seriously damage a coin and sharply reduce any collector value it may have.” You’ll also want to assess its quality. “If the coin still has its original mint luster, handle it only on the edge,” says Pearlman. “Don’t put fingerprints on the front or back, as those marks can also reduce any collector value.” Then, research the method by which you’d most like to handle your coin. For example, you could keep it, bring it to a rare coin dealer, or put it up for auction. Whatever you do, it’ll bring a whole new meaning to the term “pretty penny.” RELATED: This Is the Richest State in the U.S., According to Data.
