Tell me about it, I had to hold my breath every time I went in there to get the coins! They were in a fireproof box buried a couple inches in the floor. And the air in that closet was dry for a basement. I don't know, though. You might have a good point. If they toned, they could be AT. That's good for me they didn't!
