Silver Presidential Silverware Set

My coworker bought a set of Silver Presidential silverware. Forks, Spoons, Knives. He took them to get appraised like 20 years ago and the appraiser said they couldn't appraise it because they never seen anything like it. He also tried contacting the company that made it and they were surprised he had it because they said it was one of a kind.

He doesn't remember the company now that made it. I want to see if anyone can find any info or a general idea what it could be worth.

It has forks, spoons, and knives. The top part of the handle is round and has the presidents face. Down the handle it has quotes from the president and has the Presidents hometown and state on it. They are sterling silver. The last president e has is Ronald Reagan so that might help date it. He said hopefully he would bring them to work tomorrow so I can post pics.
