Most of the coins pictured are taken from the British Museum collection. BMC Sicily did not include plates (it had line drawings). Hill's pictures are the best illustration we have of the the BM's Sicilian coins.
These plates were taken from photocopies of the 1903 edition of Hill's work. It is for that reason the quality is low. The original had very high quality plates.
