When you look at the API Reference for the Price object, you can see all the properties that are associated with that object. You will see the currency_options property. Next to it it says Expandable which means it's not returned by default unless you ask for it.
You can read more about the Expand feature in the doc, specifically about how to include properties not returned by default here.
To summarize, you call the Retrieve Price API and pass expand: ['currency_options'] to get those back.
