Sear notes on p.206 for 984 (Constans II): "The semissis and tremissis have the same legends and types as those of Constantine IV. No definite distinction can be made between them, but as a general rule those of Constans are better engraved and of neater production, whilst those of his son tend be of cruder style, lower relief and inferior workmanship."
