There appears to be some confusion about whether these coins belong to Ariarathes IV or Ariarathes V. Wildwinds lists most of them under V, but also lists examples of identical coins under both rulers; CoinArchives lists them mostly under IV. I bought one
almost exactly the same as yours as a coin of Ariarathes V.
The coins are all dated by regnal year; yours, like mine, is dated "Year 33". I have difficulty believing that both kings just happened to issue more or less identical coins at around the thirtieth year of their reigns; surely the coins all belong to one king or the other. I just can't figure out which.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
