Your coin of Isfahan is really stunning ! it's likely a presentation coin with special re-engraved reverse die ?
For this falus of Rasht, there is no trace of print from a previous coin; the one shown by Alaedini is in same condition, with a full legible legend, slightlly smaller (30,3mm / 16,18g) but not struck from the same dies; no mention of reeding on edge ?
