A little information I found.....
This looks like a knife that is part of 12,000 sets of 5 issued for our bicentennial (possibly as early as 1974).....honoring Patrick Henry, Nathan Hale, John Adams, Thomas Jefferson, and George Washington. All the sets were serialized. I would be guessing at value for one piece, so I won't.
Hopefully others here will be able to add more for you.
