Republic 4 Reales 1840 Go-PJ AU58 NGC, Guanajuato mint, KM375.4. A slate-gray piece that reveals a considerable amount of subtle, underlying luster as it is rotated in hand, together with rainbow iridescence around the reverse peripheries. A light semicircle of what appears to be a little extra metal arches across the eagle's breast, which adds a peculiar degree of character.
