He added, "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."

The first episode of Pawn Stars debuted in 2009, and fans fell in love with the family, who runs a pawnshop in Las Vegas. Three generations of Harrisons use their eagle-eyed skills to assess what's worth big bucks and what's a fraud.

In a separate Instagram post, Rick revealed his dad lost his battle with Parkinson's Disease and confirmed he was a Navy veteran. RIP.
