        EAGLE (Green) - 1oz United States Gold Eagle
        KRAND (Green) - 1oz South African Gold Krugerrand

Notes:
GOLD GAuGE works best on a flat surface in an evenly-lit room.

The battery can be charged by connecting GOLD GAuGE to plug with the included micro-USB cable.

Under extremely rare circumstances, GOLD GAuGE may misidentify a real 1oz gold coin as another type (for example, a Maple instead of an Eagle). However, GOLD GAuGE will NOT misidentify a fake coin as a real one.
