JMS Coins is owned by James Sego, a coin expert who has been a professional coin dealer since 1986.
Sego is perhaps most famous for his work with Eisenhower dollars, about which he wrote in a book called The Authoritative Reference Guide to Eisenhower Silver Dollars with John Wexler and Kevin Flynn.
While Sego may be well-known as an Eisenhower dollar aficionado, he offers a huge array of coins through his Coeur d’Alene, Idaho coin shop. A sampling of his inventory includes high-grade certified modern coins, commemoratives, error coins and other varieties, classic type coins, gold and silver bullion coins from the United States and other nations, U.S. Mint proof and uncirculated sets, and much more.
Sego is a member of the prestigious Professional Numismatic Guild and the American Numismatic Association, and he is also an authorized dealer for the Professional Coin Grading Service and Numismatic Guaranty Corporation.
