[QUOTE="Leadfoot, post: 541545, member: 2972"]I think that the least of this coin's problem is green stuff. I think it's fair to say the coin has far larger issues than a little green spot. Furthermore, the dellers did nothing at all to stop it from corroding again. All it did was add a little bit of corrosion/toning on the fresh post-strip surfaces. If the coin is again exposed to humidity and sulfur it will begin to corrode again. Only a layer of oil -- kept up with regularly -- will stop it completely, and removing humidity/sulfur will effectively slow it down enough that it will be stable for a very, very long time. And if the coin was in the ground for any length of time (as it appears) -- some of the salts may have entered deep into the coin, and that green stuff (and other corrosion) will start again even without significant humidity/sulfur and with oil on the surface. All that said, if you are happy with the results, that's the most important thing -- and with a coin with that level of "issues" can certainly benefit from some conservation -- I still don't fundamentally agree with the position, and personally, I'd just avoid coins that have issues and seek out coins that don't.
