In the March 1966 issue of The Numismatist, numismatic dealer Aaron Feldman ran an advertisement for books. Many of the great numismatic works were listed for sale, along with several new pieces of numismatic literature. A total of 25 books were featured below the catchy headline, “Buy the Book Before the Coin.” Numismatists rapidly embraced this phrase. The saying is commonly used and is still as accurate today as it was when it was introduced.
