Pawn Stars‘ Richard Harrison, known by the nicknames “The Old Man” and “The Appraiser,” passed away on Monday after a battle with Parkinson’s disease. He was 77.

Harrison’s son and Pawn Stars co-star Rick Harrison memorialized his dad via a couple of Instagram posts, with one recent photo and one from his Navy days, as he made sure to note “what a great family man” the Old Man was and how grateful he was that the whole world got to see that.

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.
