The object of this paper is to indicate, by the aid of a few chosen examples, the kind of contribution that can still be made by Republican coins to history. Numismatic detail has, therefore, deliberately been curtailed: those who wish for more are referred to Grueber's Catalogue of the Coins of the Roman Republic in the British Museum, with its full index of moneyers' names in vol. iii, and to an article by the author of this paper, due shortly to appear in the Numismatic Chronicle, on ‘The Roman Serrati.’ A few words, by way of preface, on some points of numismatic method may, however, be in place here:
(a) From about B.C. 125, hoards of Roman coins supply us with invaluable evidence of date. A find buried in B.C. 100, for example, obviously should contain no coins of a later date than that year. Further, if it is at all a large hoard, it will probably present a fairly reliable picture of the coinage of the years just preceding. But there are two possible errors to be guarded against. Many hoards, as they reach the numismatist for description, contain a few ‘stragglers,’ i.e. coins of dates certainly later than the main body of the hoard, added, whether by accident or by intention, after the original burial. Again, there may have been special circumstances, often quite beyond our knowledge, which shut out from the hoard many issues of dates only a little earlier than the date of burial. Both these sources of error can, as a rule, be detected and allowed for, when we have a group of hoards of about the same date.
