The letters “GA” indicating a value of 1 ounce are inlaid in silver. Above these is a six- petal rosette in the centre of which is set a Christogram, also inlaid in silver. The reverse is undecorated. While the Byzantine weights system can be regarded as a continuation of its Roman predecessor, changes were observed in the names of units. Libra was replaced by litra, and scripulum by grammata, whereas the unit ons remained in use. The two dominant units of this period were coin-inspection and commodity weights. Since weights for coin-control were produced to monitor and control the weights of coins made of precious metals, coin units also designated the names of commodity weights. The key feature in the weights of the period was the inscription of the unit and its value on the weight in question.
