Typefaces with extensive Latin Language support should include currency symbols from countries that speak or use the Latin Languages it supports. I have no practical evidence of this but instead made the logical leap that if a language is used in a country, they might need to write down monetary values.
Hot take: currency symbols are a part of language support.
I researched each of the following currency symbols, which country(s) used it, what languages were spoken there, and whether the Latin script was used. Here are the symbols I support in my Latin-language fonts and why:
¤ $ ¢ £ ¥ ₤ ₫ € ƒ ₮ ₱ ₲ ₴ ₸ ₹ ₺ ₼ ₽ ₡ ₦ ₩ ₭ ₵ ₪ ฿ ₿
¤ —Currency Symbol
This little buddy is used as a ‘currency symbol placeholder’ when the official currency symbol is not available. It’s a bit of a technical relic from the days when character sets were quite limited and there wasn’t enough room for multiple currency symbols, or not all were included. It has also been reported that it might be used in the financial sector for some reason—See extended discussion on TypeDrawers. Some keyboard layouts can still access it so it’s sticking around!

$ —Dollar
The dollar symbol is used in a number of countries using Latin-based languages including Canada, The United States, Australia, New Zealand, Eastern Carribean States, and more. Source
¢ —Cent
This is the divided unit of many currencies. Source
£ —Pound
The pound symbol is used in the United Kingdom and a number of other United Kingdom Overseas Territories, many of which use the Latin script. Source
¥ —Yen
The Yen is used in Japan and in China to represent the Yuen currency when used alongside Latin Script. Latin script is used to a certain extent such as for imported acronyms and instances when non-Japanese speakers need to know how to pronounce something (Romanji) or Romanization of languages used throughout China.

Updated on July 11 2022 to correct spelling of ‘Naira’, add a note about the Florian being used in African languages, and include Chinese context for the Yen or Yuen symbol.
