Late Roman or early Byzantine bronze commercial weight –This weight is probably from the east and after weights with Roman numbers (I for a one ounce) and before only Greek numbers / letters were used. The seller proposed 500 - 650 AD. The weight has a Greek number and Roman letter to mark its weight. I can not tell from the picture if any of the original silvering is still on the weight. Simon Bendall in Byzantine Weights, pg 8, splits scale weights into commercial and coin weights. He then shows symbols for Roman and Byzantine weights. The γA on this weight is for one ounce = 27.2 grams in theory = one VNCIA (ounce) = 1/12 of an As (Roman pound). One As = 327.45 grams.
Uniface barrel- shaped 1 uncia weight. Cylindrical with a slightly bulging center and with a flat top and bottom. The top bears a center punch flanked by the engraved letters γA = 1 uncia.
