France
Louis XVI Louis gold d'Or 1786-T MS64 NGC, Nantes mint, KM591.14. There are virtually no adjustment marks we see with the exception of the weakness in the second Flue-de-Lis. Which seems insignificant considering the gorgeous slightly prooflike fields, full strike, literally mark free bust and hair, lustrous golden honey color, and marvelous aesthetics. Brilliant eye-appeal.
