Brazil
João VI 640 Reis 1818-M XF40 NGC, Minas Gerais mint, KM325.1, LMB-482. A famed rarity of the Brazilian series bringing substantial sums when seen in any condition, let alone only moderately handled. Uniformly patinated by generous battleship gray surfaces tempered by only minor instances of grade-defining friction. General central striking weakness that typically plaques this issue does little to detract from the pleasing aesthetics. While Minas Gerais is typically known for its output of gold issues, these few in silver remain some of the most hotly contested from this mint, and consistently demand a worthwhile premium.
