Cohen, Monniaes sur L'Empire Romain, Scorpion softcover reprint of the 8-volume set originally published 1880 in French, plus the extra French-English dictionary volume. Catalogs ALL Roman & Latin legend coins, with valuations, ALPHABETICALLY by legend, making it easy to use (much unlike RIC or BMC where it's a real pain trying to locate any given coin). I use mine constantly. (A softcover set brought $236 on $300 bid in my 3/93 sale.)
