Affectionately nicknamed "The Old Man," Harrison was best known for his appearances on the History Channel series, though he was on the show less frequently in recent years.
He owned Gold & Silver Pawn Shop in Las Vegas with his son, Rick. Richard Harrison was also a veteran of the U.S. Navy.
Rick Harrison paid tribute to his late father with a pair of Instagram posts earlier today. Read his messages below.
Richard Benjamin 'The Old Man' Harrison passed away this morning surrounded by those he loved. He will be tremendously missed by our family, the team at Gold & Silver Pawn and his many fans the world over. He was my hero and I was fortunate to get a very cool 'Old Man' as my dad. That I got to share him with so many others and they got to see what a great family man he was is something I am grateful to have experienced with him. He lived a very full life and through the History television show 'Pawn Stars' touched the lives of people all over, teaching them the value of loving your family, hard work and humor. We appreciate everyone's thoughts and prayers and ask that we are provided some privacy at this time.
