I thought you were a chemist? I find it facinating that you believe the chlorine ion in aqueous solution is perfectly happy and that it will not...
Exactly correct! This is one of the reasons I greatly prefer using deionized water over distilled water. Plus, distilled water can contain low...
The chlorine anion is very aggressive toward ALL metals. You're making it sound like it's perfectly fine and that's not true at all.

I'm passing on voting this time. NGC is too unpredictable on coins like this. My guess would have been AU-53. There's just too many signs of...
WOW! Stunning coin! That thing is HAMMERED to boot!
That's definately strange looking!
