The coin you show is probably a
tetradrachm, not a
drachm. On Cappadocian drachms you don't have two lines of
legend on the right
side of the
reverse.
Otto Mørkholm attributed this
type in "Some Cappadocian problems", NC 1962, pp. 407-411, to Ariarathes IX as well as François de Callataÿ in "L'histoire
des guerres mithridatiques vue
par les monnaies", Louvain-la-Neuve 1997, P. 201.
This is the latest I know
.
