Obsolete currencies and their replacements

What you’ll practice

Many currencies disappeared through reforms, independence, inflation, or entry into a currency union. This quiz helps you recognize which modern currency replaced an older one - and in some cases, which interim currency bridged the change.

Every question uses 4 options and there’s no timer, so you can think through tricky transitions like splits, pegs, and rebrands without pressure.

Difficulty and pacing

Difficulty is mixed: you’ll see well-known swaps (like euro adoption) alongside less familiar replacements from short-lived states or rapid redenominations. Adjust the question count and difficulty before you start to tailor the run to a quick warm-up or a deep study session.

Common pitfalls to avoid

• Mixing up similarly named currencies (old/new “dinar,” “peso,” or “leu” variants)
• Confusing a redenomination with a full currency replacement
• Assuming the euro replaced every legacy currency at the same time
• Forgetting interim currencies used during transitions or conflicts
• Overlooking cases where a currency returned after a temporary change

Tips for better scores

Look for historical cues: independence dates, political unions, and inflation crises often explain why a currency vanished. When two options seem plausible, ask whether the change was a rename, a revalue, or a switch to an entirely different monetary system.
