Google Only Tracks 1 Price per URL for Search so Don’t Add Structured Data with Prices in Multiple Currencies
https://reddit.comAre you looking to add structured data for products with prices in multiple currencies? Well if you are doing that with SEO in mind don’t bother since Google only tracks 1 price per URL in search. Personally I would avoid doing anything that can confuse the G bot. This bit of info came from John Mu in a reddit thread.
