Paraguay, white-metal pattern 10 reales (1854-67) obverse struck with the obverse of a French 5 francs of Napoleon III (1861-70), encapsulated NGC MS 61. KM-799.1 (France). Nice but uneven rainbow toning with much underlying luster, minor marks here and there, interesting and unique mint sport struck while Paraguay was using the Paris mint to make their coins, this denomination never actually issued for Paraguay. (Estimate: $2500 - 5000)
