'Prints from the coin engravings can be found stuck in among [Bell's] papers, and the fullest set is in Trinity College, MS R.10.12 = James 1901-1904, no. 855. It begins with a sort of visual catalogue of all the images that Bell had prepared, numbered and ranging in chronological order from Julius Caesar (4) to Mariniana (109): there is no sign of any later images and even the 109 have a number of gaps, there being engravings of only 70 of the relevant 109 persons.' (Burnett 2020b, p. 1657)
