João VI 200 Reis 1818 MS64 NGC, Lisbon mint, KM357. A scarcely-offered issue, this present selection displays gunmetal patination with underlying shades of electric blue, coppery-red, and champagne, all of which illuminate upon rotation and set the design elements alight in a beautiful canvas of color. Nearly-Gem and quite possibly deserving of a finer title, most desirable in this visually enchanting quality.
