Very nice example muddler! It looks very clean on both the obverse and reverse. Great additon to your collection. Glad you were able to get the coin at a savings from previous market highs.
I've always thought that the three coins of the Capitol Visitors Center program worked well at educating folks about the roots of the magnificent building that is today's US Capitol. Highlighting the smallish original building that housed Congress, the Supreme Court and Library of Congress was, IMO, a thoughtful way to encourage folks to seek out more information about the Capitol's development.
The Architect of the Capitol web site has a very good video that describes the Capitol's growth. Check it out for more: US Capitol History.
