June 25 (UPI) -- Richard 'Old Man' Harrison, a star on History's long-running reality series Pawn Stars, has died at the age of 77.
The Facebook account for the Gold & Silver Pawn store at the center of Pawn Stars announced Harrison's death on Monday. The cause of death remains unknown.
"It is with heavy hearts that we acknowledge the passing of Richard Benjamin Harrison (known as 'The Old Man' to Pawn Stars fans the world over) this morning. He was surrounded by loving family this past weekend and went peacefully," the post said.
"The team at Gold & Silver Pawn and the Pawn Stars family is grieving his loss. He will be remembered as the best father, grandfather and great-grandfather you could have by his family and by fans as the sometimes grumpy (always loving, however), often wisecracking, and voice of absolute reason on the History television show Pawn Stars. Services are pending and the family appreciates your prayers and kind words," it continued.
Harrison has appeared on Pawn Stars since its debut in July 2009 but has been featured less frequently on the program in recent years. Harrison opened up Gold & Silver Pawn in the 1980s with this son Rick who also stars on the show along with Rick's son Corey and family friend Austin 'Chumlee' Russell.
"We are deeply saddened by the loss of our friend Richard 'The Old Man' Harrison, a beloved member of the HISTORY and @pawnstars family. He will be greatly missed for his wisdom and candor. Our thoughts are with the Harrison family during this difficult time," History said on Twitter.
