Æ Unit - Ujjain

Ujjain sat at the intersection of two major ancient trade routes — the north-south Uttarapatha and the east-west corridor connecting the subcontinent's interior to the western ports — which explains the dense concentration of punch-marked and cast copper issues from this region during the late Mauryan and post-Mauryan transition. At 0.75g, this piece falls at the lighter end of the local unit series, possibly reflecting regional weight standard fragmentation as Mauryan administrative control receded after roughly 185 BC.
