However, Reddit has come through with a global map - although with a little more of a broad brush.
The map, made by a Reddit user and posted to a popular mapping subreddit, shows some of the currency families and shared names around the world:
The post also came with some notations and edits after commenters pointed out errors:
If you're curious as to how currencies get their name - most are named after Latin roots or after a specific weight.
Pound is obvious, Dinar comes from the Latin for denarius (a coin), whereas the Dollar comes from the Joachimsthal valley in the modern-day Czechia where silver was mined. The silver became known as Joachimsthaler, later shortened to Thaler, Daler and so on.
Krone/Krona comes from the Latin corona (meaning crown), while the Lira comes from the Latin libra (pound).
