Pedro II gold 20000 Reis 1862 AU58 NGC, Rio de Janeiro mint, KM468, LMB-682. The indisputable "king" of the Pedro II 20,000 series, with a catalog value nearly 20 times that of some of its higher mintage counterparts in LMB. The Standard Catalog of World Coins simply notes the date as "Rare" and gives no attempt to provide a book value. Despite circulation, glints of mint luster express themselves throughout the fields, and essentially full detail remains both across Pedro's bust and in the reverse shield design.
