Frankly I'm always weirded out when a former Spanish colony DOESN'T use the peso. Literally means pound. Same as the UK. I almost forgot Las Filipinas.
Good god! I'm dumb. Got everything, including the Philippines, except for the most obvious one, Mexico. And that's after trying all the Spanish speaking central American countries.
I was sure there was an African country or two, but I was probably thinking of the franc. Glad I finally remembered South America in the end (where I live...)
Frank, Pound, Dollar, Dinar :)
