Understood. However, the letter attests to its being made for some special purpose and the coin is clearly "nicer" than others. They did not have any better equipment, although a die could have been polished. There weren't other options at a regular mint. Only Philadelphia had the ability to do really special things. To my skeptical mind, this coin has documentation supported by appearance to justify an individualized moniker. On appearance alone, it would not qualify. (It sold for over $400,000.)
