Why does Google show exchange rates between EUR and CHF for the 80s and 90s if the Euro was introduced only in 1999?

   “Looks like all their data goes back to 16 Apr 1982, e.g. GBP/USD has the same starting point.”

   P.S. I wrote Google a mail, expect to get an answer in 10-15 years, until them we have AI generated data from the € to CHF ratio in 1456.

2. Before January 1st 1999, there was the ECU ([European Currency Unit](https://en.wikipedia.org/wiki/European_Currency_Unit)), established in 1979. On that date 1 ECU became 1 EUR.

3. They might use the [ECU](https://en.wikipedia.org/wiki/European_Currency_Unit) for the time before the Euro. Just a guess though.

4. He knows too much now…

5. They might refer to the [ECU](https://en.wikipedia.org/wiki/European_Currency_Unit) standard prior to 1998.

6. Just in case you’re curious

7. Wait EURO is that young?!

8. Because before Euro it was Deutsche Marke, before DEutschropäische Union it was BRD, and so on…
