No die-striking assembly has been discovered so far from any of the ancient sites. Several coins, scrutinised under microscope, show homogeneity or near-homogeneity in size of the grains of their metal. This indicates that either the blank or the die-struck coin might have been heat-treated to promote a good amount of recrystallisation and homogenization of grain-sizes. (Mukherjee, 1988: 21)
