Welcome to Numista!
I assume you are referring to prices listed in the catalogue in year lines, like these, right?
Those prices are calculated based on an average price reported by members who have the coin; they are in Euros, but you can easily convert them to Pesos with any currency converter. You can actually change your displayed currency by going to s
ettings and going down to the Personal options section, but I'm not sure if this applies only for bullion prices or for catalogue values as well.
