$1 2001-P Capitol Visitor's Center, NGC MS69. The Capitol Visitor's Center commemorative coin was first issued by the United States Mint between February 2001 and March 2002 and were authorized to commemorate Congress convening in the Capitol in the year 1800. Our founding fathers dubbed the Capitol the "workplace of our legislature" making it a definitive symbol of our democracy. Even the foresight of those same men would not have realized the Capitol receives over five million visitors every year.
