According to Harlan Berk: "Seltman's "Civic Mint" issue, though misnamed by him and dated too late, contained some very interesting coins, including the earliest to bear the famous Athena/owl types at Athens in our opinion. According to Seltman, the tetradrachms of this group were "superior in technique and style" and "the finest medallic coins ever produced in Athens"; Athena's feature and helmet on the obverse were "carefully and effectively treated", while the owls on the reverse were "of special merit", "reminiscent of the style of the vase-painters of the period"
