Last week Sharp was indicted by a federal grand jury in Detroit, replacing the criminal complaint originally filed against him.
Federal magistrate Steven Whalen entered the not guilty plea for Sharp, whose pickup was found containing 104 bricks of cocaine when he was pulled over for a traffic stop on Oct. 21.
He was initially stopped for improper lane use on Interstate 94 in Washtenaw County, Mich.
Police say a police dog sniffed out the drug haul.
Sharp is charged with possession with intent to distribute cocaine. He says he grows lilies on his 46-acre farm.
