  ($2500) An ambitious city like Thurium could hardly be left behind in
  the new bronze coin fashion sweeping southern Italy. The magistrate
  Damon was charged with issuing a large bronze coin resembling the
  celebrated signed dinomos (SNG ANS 959), at first on a heavy standard
  of about 36-40 grams. It probably represented the bronze equivalent of
  an Attic drachm, but was too heavy for the half of an Italian silver
  nomos of about 8 gram and was almost immediately replaced with a much
  more successful coin of the standard types and weighing about 30 grams
  to which a whole range of attractive smaller denominations was
  appended.
