John Dannreuther is one of the numismatic world's most highly esteemed coin dealers. An original founder of PCGS, he explains the origins of the company, that in part, began with discussions over Red Book pricing. "One of Dannreuther's most noteworthy numismatic accomplishments was co-founding Professional Coin Grading Service (PCGS) in 1986. It began as a book project when he, David Hall, Bruce Amspacher and Gordon Wrubel met after coin shows to discuss writing a series of numismatic texts on each denomination. Instead, they decided the coin business needed guarantees of authenticity and grading to combat the abundance of overgraded coins, altered and repaired coins, and fakes at shows."
