Questions... since I have rinsed and cleaned it a little, will it begin to deteriorate now? And is there a safe way of keeping it in its current condition? I've seen in here that some recommended Verdi-Safe or something to that effect. Would it be okay to find and use this on a coin of this nature? I ask because since it's had the dirt removed and rinsed, I've seen a few little specs of green showing up and I know corrosion is the killer of copper coins, is it not? This is my first one and now wishing I had just simply brushed the dirt off and gone no further.
Recommendations? Thinking of running out and getting a couple of air-tites for it.
