directly useful for much, except maybe as firelighters, but it's still generally accepted that most vendors will accept them as payment for goods and services. You might need a lot, or need to exchange one country's money for another, but the cash is worth something. Not so with this currency.
Usually this applies to the currencies of no-longer-existing governments, such as Confederacy dollars or Reichmarks, or governments that don't exist yet. It also might just be a scam.
Compare Global Currency Exception, which is mostly a video game trope, and Worthless Yellow Rocks, where a priceless rare material to one party is completely worthless to another who has an over-abundance. If it still has some value go to Ridiculous Exchange Rates or Ridiculous Future Inflation. This trope is sometimes used to put the "worthless" in a Worthless Treasure Twist.
- Archie Comics: Subverted in a story where the gang finds an old chest in the basement of Pop's Chok'lit Shoppe that contains, among some other Civil War memorabilia, a bunch of Confederate money.

Because Tatooine is outside of the Republic and moreover in the ass-end of space, Watto tells him to get him some real money.

- In McAuslan the main characters find a hidden treasure in a fort in the middle of the Arabian desert. Unfortunately, it's all in war-era Italian lire notes. The story is set in 1946 so Mussolini's government is no longer around to back the notes, meaning that the whole trove is worthless.
- A variation shows up in The Odessa File: part of the backstory of a Master Forger side character was that when Germany was under 4-power occupation, he became an expert at forging various documents as well as Allied "Occupation Reichsmarks"; however, when the new West German Mark was introduced as a currency, every household was given a set amount of the new Mark without any conversion or exchange of existing currency reserves, rendering the fortune he forged worthless overnight.

- Star Wars Legends: A couple examples occur in the post-Return of the Jedi period due to the state of war between the New Republic and the Imperial Remnant, which means it's impossible to exchange Imperial currency for New Republic currency—nor is it very easy to exchange Imperial currency anywhere else, due to the Empire's horrible reputation.
- The Thrawn Trilogy: A Rodian attempts to pay a Barabel with New Imperial scrip, which can't be spent anywhere except on Imperial worlds.
- X-Wing Series: Exaggerated in Solo Command. Nawara Ven offers Edda Gast immunity from prosecution for war crimes and a new identity with a fortune of half a million credits, in exchange for intelligence on a genetic engineering project of Warlord Zsinj's. She insists, however, on being paid in Imperial credits. Nawara conveniently neglects to inform her that attempting to bring that much Imperial currency through a New Republic port without the proper security clearances carries a life sentence for sedition.

- Played with in The Mandalorian. In the first episode, Din Djarin refuses payment for bounties in Imperial Credits, though since Greef Karga says "They spend," it's ambiguous whether this is because of the Empire being reduced to The Remnant, or the Mandalorian Tribe having a grudge against the Empire for The Purge of their home planet. He is told the only other option is half value in Calamari Flan, but he still chooses that over the Imperial credits. When he takes a job from the Remnant later, they offer to pay in beskar steel ingots.
- A The Swamp Fox episode where Marion's men pay a tavern owner with Continental money, which is worthless at the time. He's a Tory and not happy.

- Fallout series:

Despite it being board game money, Bubs considers the amount that Strong Bad is paying to be more than a million "Poopies".
- Exaggerated at the end of the Gravity Falls episode "Irrational Treasure," when Quentin Trembley gives Dipper a negative twelve dollar bill with Trembley's face on it as a parting gift. Looking at the text on the bill, you can see it's not legal tender.
Dipper: Whoa. This is worthless.
Trembley: It's less than worthless, my boy!

- Regular Show: This is a bit of a Running Gag (even dating all the way back to the creator's student film, The Naive Man from Lolliland) with Pops who comes from Loliland and thus the currency there is lollipops, or he might just be a Cloudcuckoolander. So when Mordecai and Rigby ask for money or he offers to pay himself, his money is worthless.
- Scooby-Doo, Where Are You!: Scooby-Doo, upon completing a challenge to stay a whole night in a "haunted" house, inherits a large sum of money from the late challenger. However, it is revealed that the money is all Confederate dollars, rendering it worthless in post-Civil War United States.

Clerk: That'll be six dollars.
Cartman: Okay... and how much is that in "pubes"?
Clerk: (beat) We don't take "pubes".
Cartman: (defiant) Listen, my money is as good as anybody's! Don't you, uh, discriminate against my people by not accepting these pubes.
Clerk: We don't take pubes! End of story!!
Cartman: (storms off) RACIST!!!

- A zig-zagged example from real life: Lily Allen tweeted that in 2009 when cryptoocurrencies were new, she declined an anonymous fan's offer of over 200,000 bitcoin for an online concert: an amount that had no real-life value then, but would be worth almost £1.5 billion (~$2 billion US) now, making this a massive and painful subversion. However, it's speculated that since bitcoin was so new at the time that no one except its creator would've had that many, the offer might have actually been in Second Life's Fictional Currency Linden Dollars, in which case it would be a straight example since those are still worth nothing today.
- Joshua Norton was an insane man who lived in San Francisco in the 1860s and proclaimed himself "Emperor of the United States and Protector of Mexico". While he had no actual political power, the citizens of the city loved him and played along with his delusions. He even printed up his own "currency", which several local bars accepted as payment (at least from Norton himself).
