World Currency Nicknames: Buck, Quid, Loonie & More

Tap a currency to see its nickname and where it came from.

🇺🇸 US Dollar — "Buck"

A $1 bill is commonly called a "buck," most likely tracing back to a time when deer hides (buckskins) were traded like currency on the American frontier.

🇬🇧 British Pound — "Quid"

Slang for one pound sterling. The exact origin is unclear, though one theory traces it to the Latin phrase "quid pro quo" (something for something).

🇬🇧 British Pound — "Fiver" / "Tenner"

Distinctly British casual terms: a £5 note is a "fiver" and a £10 note is a "tenner."

🇨🇦 Canadian Dollar — "Loonie"

The $1 coin is nicknamed after the loon bird engraved on it; the $2 coin, in turn, is called a "toonie."

🇪🇺 Euro (France) — "Balle"

A casual French word for money — literally "ball" or "bullet" — that carried over from the franc era and is still commonly used to mean euros today, as in "dix balles" for ten euros.

🇦🇺 Australian Dollar — "Prawn," "Lobster," "Pineapple"

Australian banknotes are often nicknamed after their color: the pink $5 note is a "prawn," the red $20 note is a "lobster," and the yellow $50 note is a "pineapple."

🇮🇳 Indian Rupee — "Peti" / "Khokha"

Informal terms for large sums: "peti" (literally "box" or "trunk") means 1 lakh (100,000 rupees), and "khokha" means 1 crore (10 million rupees).

🇯🇵 Japanese Yen — "~Endama"

Coins are casually referred to by adding "endama" (yen coin) after the amount, so a 100-yen coin becomes a friendly "hyaku-endama."

🇰🇷 South Korean Won — "Jang," "Mungchi"

In everyday conversation, Koreans casually refer to 10,000 won as a "jang" and larger stacks of cash as a "mungchi" (bundle).

🇿🇦 South African Rand — "Bucks"

Much like in the US, South Africans casually call the rand "bucks" in everyday conversation.

Why Do Currencies Get Nicknames?

The currencies people handle most often in daily life are the ones most likely to pick up a casual nickname. Animals or people stamped on a coin, a note’s color, and historical background have all inspired these fun, informal names over time.
