I've looked for what might be currency used by the Romulans, but couldn't find anything either on Memory-Alpha or any memories concerning TOS or any spinoffs- has anyone ever found something that might answer this question?

  • I agree there's not likely an answer. TNG Unification when Picard and Data are in a Romulan Cafe the owner gives them the soup because she's highly suspicious. Which would have been a rare opportunity to see payment. "WOMAN: Doesn't matter to me. I don't know when he opens. Eat your soup, courtesy of a loyal establishment. Jolan tru." Or they have perfect communism. Commented Oct 2, 2021 at 0:21
  • The only form of currency that I'm aware of in Star trek is gold pressed latinum Commented Oct 3, 2021 at 0:02
  • @SpacePhoenix- there are also Bajoran Litas, Klingon Darseks, Cardassian Leks, the Vlugta government uses a currency called an Isik.

  • @Nu'Daq - The Klingons also use Talons and the Federation have Credits.

  • @Nu'Daq that could be where the phrase "Isik for your thoughts" comes from (used a couple of times during Star trek: Discovery season 1) Commented Oct 4, 2021 at 0:13

TV/Film Canon

We don't know. As lucasbachmann has mentioned in a comment, we do know that they have some sort of exchange system because when Picard and Data visit a classy Romulan establishment in TNG: Unification, Part I, the owner gives them their meal for free because she thinks they're government stooges. Unfortunately, we don't get a mention of what they use for money, nor do we see it being used.

SOUP WOMAN: It doesn't matter to me. I don't know when he opens. Eat your soup. Courtesy of a loyal establishment. Jolan True.

EU Canon.

Chains (Takhse) or Marks

Within the EU, we have a little more info to go on, particularly from the Diane Duane Rihannsu novels, largely set on Romulus. There are umpteen mentions of "cash" and "money", often in relation to 'chains' which appears to be interlinked rings of metal.

Arrhae had once, very diffidently, made the suggestion, and had sparked a tirade of startling intensity for daring to presume that “a few dirty chains of cash” could buy the property that his ancestors had enriched with their blood.


How I detest you! Ael thought as she went past the narrow, dark, cold-faced little woman. You would sell your sisters'-sons and -daughters to Orion slavers for a quarter-chain of cash if the deed would buy you power. No matter, though; you and yours will be rid of me soon enough. Ael stepped into the lift. "Ri'laefv'htaiell, Enarrain," she said, and waved the lift doors shut.


she made off with as much haste as dignity and a full load of groceries permitted, leaving the man holding uncollected change from five full chains of cash and wondering what had happened to so suddenly increase House Khellian’s opinion of its own honor.

The in-universe history book Star Trek - Federation: The First 150 Years suggests that whatever the Romulans use for cash has sufficient space to put a picture of their Emperor on.

The portrait of Gileus I, which was used on Romulan currency

And Star Trek Online uses something called Romulan Marks. This seems pretty dubious as a source though, because a hecka lot of other races also seem to use them and the writers apparently just used them as a placeholder when they didn't have a set answer for the existing currency.

I have been unable to find the in-universe origin of this word (e.g. who invented it), but it does appear in most every version of the online Romulan Dictionary.
