Have you ever heard anybody use the term mule coin?
A mule coin is a coin that has an obverse (heads side) and reverse (tails side) design that wouldn’t ordinarily go together on the same coin.
Mule coins have long attracted the interests of coin collectors. Such coins produced by accident are high on the want lists of many error coin collectors!
One of the most popular mule coins is a dollar-size coin showing the obverse of the Washington state quarter and the reverse of a Sacagawea dollar. It had sold for over $40,000 when first found and authenticated!
My love for coins began when I was 11 years old. I primarily collect and study U.S. coins produced during the 20th century. I'm a member of the American Numismatic Association (ANA) and the Numismatic Literary Guild (NLG) and have won multiple awards from the NLG for my work as a coin journalist. I'm also the editor at CDN Publishing (a trusted source for the price of U.S. rare coins), editor at the Florida United Numismatists Club (FUN Topics magazine), and author of Images of America: The United States Mint in Philadelphia (a book that explores the colorful history of the Philadelphia Mint). I've contributed hundreds of articles for various coin publications including COINage, The Numismatist, Numismatic News, Coin Dealer Newsletter, Coin Values, and CoinWeek. I've also authored nearly 1,000 articles here at The Fun Times Guide to Coins — and I welcome your coin questions in the comments below!
