About this site

A reference for physical money: what each currency consists of, whether the notes in your hand are still worth anything, what exchanging them really costs, and what you may legally carry across a border.

How the data is sourced

Every record carries its sources and the date it was last checked, and both are printed at the foot of the page. Nothing is published without them, the build fails if a record has no source or no verification date.

Sources are marked by tier. Primary means the issuing central bank, the customs authority, or the legislation itself. Secondary means a credible reference work, used where a primary source is unreachable, several central banks publish only through JavaScript applications or block automated access entirely. We say which is which rather than blurring them, because someone deciding whether to post a banknote to a central bank deserves to know where we read it.

Checks that run on every build

• Every record must carry at least one source and a verification date.
• A note marked still exchangeable whose deadline has passed is a hard error, that is the failure that would actively mislead someone.
• Rendered pages are compared against the source data, so a formatting helper cannot quietly round a figure. This caught a fixed conversion rate of 1.95583 being displayed as 1.956.
• Minor units are cross-checked against the ISO 4217 register.
• A route page is never generated unless both countries have verified rules.

What we deliberately do not do

• We do not sell currency, transfers, or cards, and take no commission. Every other exchange calculator we found is run by someone who profits from the answer.
• We do not publish live exchange rates as a product. XE and Wise do that well; we cover the physical money they do not.
• We do not track currency "revaluation" news. Our scam pages debunk those schemes and stop there, chasing that traffic would make us part of the problem.
• We do not reproduce banknote images. Reproduction is restricted by counterfeiting law in many countries. Descriptions and diagrams only.
• We do not fill gaps with guesses. A page that says "we have not checked this yet" is more useful than a confident wrong number.

Accuracy and corrections

Rules change. Exchange deadlines pass, thresholds are revised, and new series enter circulation. Each page shows when it was last checked so you can judge how much weight to give it, and anything legally consequential links straight to the authority so you can confirm it before acting.

This site is general information, not legal, tax or financial advice. If you spot something wrong, we would rather know: corrections are the cheapest thing we can do.
