How to Identify a Foreign Banknote
Identifying an unfamiliar note is a process of elimination, and it usually takes under two minutes if you work in the right order. The alphabet narrows it to a region, the country name or emblem fixes the issuer, and the numerals and date place the series.
The steps below work for any note from any era, including currencies that no longer exist. Once you have the country and denomination, the value question becomes straightforward.

Step 1: identify the script
Latin script covers Europe, the Americas, and much of Africa and Southeast Asia. Cyrillic points to Russia, Ukraine, Serbia, Bulgaria, and the former Soviet republics. Arabic script covers the Middle East, North Africa, Pakistan, and Iran. Chinese characters point to China, Taiwan, Hong Kong, Japan, or Korea.
Devanagari indicates India and Nepal. Thai, Burmese, Khmer, Hebrew, Greek, Amharic, and Georgian scripts are each distinctive enough to identify a single country or a very small group.
Step 2: find the issuing authority
Almost every note names its issuer somewhere on the face, usually as a central bank: Banco de, Banque de, Banca d, Bank of, Reserve Bank of. That phrase is your strongest single clue and often appears in both the local language and English or French.
If the issuer is not legible, look for a national coat of arms, a flag, or a recognizable landmark. Colonial-era notes frequently carry a British, French, or Portuguese emblem alongside the local name.
Step 3: read the denomination and date
The large numeral is the denomination. Watch for notes that use local numerals rather than Western digits, particularly Arabic-Indic numerals on Middle Eastern notes, where the shapes for zero through nine differ from what you may expect.
The date can be a year of issue, a series year, or in some cases a date in a non-Gregorian calendar. Islamic calendar dates on Middle Eastern notes run several hundred years behind the Gregorian year, and Thai notes use the Buddhist era.
Step 4: check whether the currency still exists
Many notes people find are from currencies that were replaced: the euro absorbed twelve national currencies, the Soviet ruble split into a dozen successors, and multiple African and Latin American countries have redenominated after inflation.
A withdrawn currency is not automatically worthless, but its value comes from collectors rather than from exchange. Some central banks still redeem old notes indefinitely; others closed the window years ago.
Before you do anything else
- Photograph both sides flat. Many identifying details, including the issuer name, sit on the reverse.
- Large zeros do not mean large value. Hyperinflation notes carry huge numbers and are worth very little.
- Serial number prefixes and signature varieties matter for value once you have the country and series.
- Watch for specimen or cancelled notes, marked with punched holes or overprinted text. They are collected separately.
Frequently asked questions
How do I find out what country a banknote is from?
Start with the alphabet, then look for the issuing bank name, which almost always appears on the face. A coat of arms or national emblem confirms it when the text is not legible.
Can I exchange old foreign currency at a bank?
Rarely. Most banks will not handle withdrawn currencies or small amounts of foreign cash. Some central banks redeem their own old notes indefinitely, but many have closed that window permanently.
Is a foreign banknote with a huge number worth a lot?
Usually the opposite. Very large denominations almost always come from hyperinflation episodes, where the currency became nearly worthless. Those notes are collected as curiosities and typically sell for a few dollars.
