I've been collecting coins that are very shiny and gold looking that are not very common. It's 100% natural, I didnt clean it, polished it, or anything like that, I just achieved it as changed, and over the time it grew big, I gained 10 peso commemorative coins of heneral luna that are gold and shiny, and other normal 10 peso coins from 2015 that are also like that. So I'm wondering how much they're worth.
