The story

Berk.34 records an agreement concerning vineyard taxation in the Qom district, with the liability described in drahms. This establishes local fiscal reckoning; the precise nature of the religious differential remains interpretive. [1]

Berk.154 values agricultural produce in drahms toward a money-tax payment and totals 45 stēr. Benfey identifies the total as 180 dirhams: stēr is an account multiple within this reckoning. [2]

Turning points

Under Khusro I, annual poll assessments were graded at 4,6,8 or12 dirhams

Under Khusro I, annual poll assessments were graded at 4,6,8 or12 dirhams. The 531–579 reign bounds a retrospectively reported fiscal witness, not a currency foundation or contemporary dated document. [3]
