Copper Lovers: What is Your Opinion on the Use of Chemicals to Protect Old Copper?

And when you let it air dry that saturation goes away Thad.

Yeah, I know, and then it looks normal.

Yeah, I agree, it does do that. But then it will not look normal.

And no Thad, the coins will not corrode if you do as I suggest. As long as you then put them in a quality holder and store them properly.

Metal does not soak up water like a sponge. And once the coin is allowed to dry, any and all excess moisture is gone because it evaporates. The only moisture that is still on the coin will equal the humidity that is in your home. And then it will look natural because coins exposed to the air acquire the same humidity that is in the air, that is what makes them look natural.

I'm not trying to convince you Thad, you will believe what you want to believe no matter what I say. I'm merely trying to explain for the other folks that read this how and why what I suggest works. When it comes right down to it it's really common sense.
