<p>[QUOTE="joecoincollect, post: 2037021, member: 71338"]What you say is true. I've seen many corroded coins slabbed by the top two. I saw a Australian large cent around the year 1920 or 30 with green corrosion (which means it's active and already eating through top thin layers of the coin, right?) graded VHF or xf. I have a French five francs around the 1860s that obviously was cleaned at some time and looks porous in the fields, yet it got a xf. And there's all the classic US coins like you mentioned. Let's say your right about this coin above being corroded, which I kinda believe more now. I can see it suffering toning/corrosion (these two are quite the same, depending who says what and how they are used) and then being dipped to remove it, leaving porosity. Wouldn't you still say the corrosion is quite limited and not active? I don't think it should be detailed graded when compared with others that are[/QUOTE]</p><p><br /></p>
