The euro, the currency of most of the European Union, went live in 1999. In 2002 physical money appeared and began replacing the likes of the French franc and German mark. You would therefore imagine that the euro postdates the typewriter age by quite some margin. And you would imagine wrong.
My KOFA 300 typewriter has the euro symbol on it! Typewriters continue to be made in China to the present day and the KOFA came from such a factory some time in the early twenty first century. It was listed on eBay as "vintage" natch.
