This is a series of five volumes begun in 1952 by Herbert A Seaby.  dealing exclusively with the Roman silver coinage from the Republic through to Romulus Augustus.
It is based on the works of Cohen, so the coins are listed in alphabetical order of the reverse legends, which makes for fast and easy finding.  Volume 5, written much later than the others, is by Cathy King.  The latest editions have been revised by D R Sear and R Loosley. Valuations by various people, including David Sear.
