There is a particular kind of end-of-holiday ritual every traveller knows. You empty your pockets, find a boarding pass you forgot to throw away, a café receipt you definitely did not need to keep, and somewhere between them, a few notes of foreign currency. Before you rush to exchange them, look again. Because sometimes, the prettiest souvenir from a trip is the one you were carrying in your wallet all along.Around the world, banknotes double as miniature canvases, capturing everything from rare wildlife and dramatic landscapes to architecture, history and national identity. Some are so beautifully designed that spending the last one almost feels wrong.So, forget the fridge magnet for a moment. Here are seven currencies that deserve a place in your travel scrapbook.Seychelles Rupee, Seychelles
Seychelles Rupee (Canva)
If a destination could turn its biodiversity into pocket-sized art, Seychelles comes remarkably close. The Seychellois Rupee celebrates the archipelago’s endemic flora and fauna, making its notes feel like miniature illustrated introductions to the islands.The currency series follows the theme “Seychelles’ Unique Biodiversity – the Backbone of our Economy,” with different denominations showcasing species found across the archipelago. Look closely and you may spot the Seychelles Black Paradise Flycatcher, Seychelles Sunbird, Seychelles Kestrel, Seychelles Scops Owl, tiger chameleon and native plants woven into the designs. Even the updated SCR500 note, introduced in December 2025, continues the biodiversity theme, with its security features including a holographic stripe depicting a sea turtle swimming through waves.It is the kind of currency that feels unmistakably connected to where it comes from. Keep one after your trip and, years later, it may bring back memories of granite-framed beaches, forest trails and the wonderfully unusual wildlife of the islands. Consider it a souvenir that conveniently fits inside your passport.Swiss Franc, Switzerland
Swiss Franc (Canva)
Trust Switzerland to make even its banknotes impeccably designed. Rather than relying on conventional portraits of famous personalities, the current Swiss Franc series explores “the many facets of Switzerland” through abstract ideas and visual storytelling.Each denomination revolves around a different theme: time, light, wind, water, matter and language, with hands, landscapes, globes and other details turning the notes into something closer to graphic-design collectibles. In other words, this might be the rare occasion when discovering leftover money in your suitcase is genuinely exciting.Costa Rican Colón, Costa Rica
Costa Rican Colón, Costa Rica (Canva)
Costa Rica’s currency seems determined to remind you exactly where you have travelled. Its colourful banknotes celebrate both the country’s cultural history and extraordinary natural wealth, with ecosystems and wildlife forming an important part of their visual identity.Depending on the denomination, the designs take travellers into forests, mangroves and other habitats, featuring native species and landscapes. It feels less like opening a wallet and more like flipping through a very tiny nature guide.Bermudian Dollar, Bermuda
Bermudian Dollar, Bermuda
The first thing you may notice about Bermuda’s banknotes isn’t necessarily what is printed on them. It is how they are printed.The notes are famously designed in a vertical format, immediately giving them a distinctive appearance. Their colourful imagery celebrates the island through birds, marine life, landmarks and ocean-inspired scenes. Designs have featured everything from the Longtail to historic churches and Gibbs Hill Lighthouse.Definitely not one to accidentally hand over with your final airport coffee.New Zealand Dollar, New Zealand
New Zealand Dollar, New Zealand
New Zealand’s banknotes are a colourful celebration of the country’s identity, pairing notable New Zealanders with native birds and landscapes. They are bright, detailed and wonderfully recognisable, exactly the sort of note that can transport you back to a journey long after you’ve returned home.Tucked into a travel journal, one becomes less about its monetary value and more about the story attached to it.Norwegian Krone, Norway
Norwegian Krone, Norway
Norway took an unusually contemporary approach to its banknotes, drawing inspiration from the country’s relationship with the sea.One side carries recognisable maritime imagery, while the other transforms those ideas into striking, pixelated interpretations. The result feels distinctly Scandinavian: clean, modern and unexpected.If most currency looks traditional to you, Norway’s Krone might change your mind.Mexican Peso, Mexico
Mexican Peso, Mexico
Mexico’s colourful banknotes bring together different chapters of the country’s history with its landscapes and ecosystems. Rich illustrations, wildlife and cultural references give the notes the feel of tiny artworks rather than purely functional pieces of paper.They are the sort of designs that reward a second look, which is perhaps the best argument for saving one instead of spending every last Peso before heading to the airport.The souvenir that mattersWe tend to return from holidays carrying things specifically chosen to remind us of where we’ve been: postcards, magnets, coffee, crafts and an alarming number of airport purchases. But perhaps the most interesting souvenir is already hiding in your wallet.
