I have the 1976 reprint of
Vol. II. Unfortunately there is no introduction stating the nature and extent of the
additions and corrections. Only the notice "Second edition prepared by R.A.G.
Carson" on the title page alerts the reader that changes must have been made.
I believe the main goal of the revision was to add new BM acquisitions of
types previously absent from the
collection.
When such a
type had been recorded in the text of the old edition with an asterisk in the margin, that asterisk was changed to a number with letter, e.g. "226 A", the
weight and
die axis of the new spec. were added, and its
provenance was stated in a footnote.
Other new BM acquisitions have been added to the ADDENDA on pp. 425-34, increasing its length by about one page.
No new pages or plates were added, excluding the possibility of more extensive revisions. For example Mattingly's misattribution to
Tarraco of a slew of Rome-mint bronze coins of 71 AD remains.
