Considering this is your first post, I'm not sure how anyone here could have said anything!!! However posting it in someone else's thread from 2013 probably won't bring many answers. Try making your own thread and posting some in focus, cropped full-size pictures.

 

First, welcome to the neighborhood, Michael!

I'm not an expert when it comes to chemicals, but I always thought that mercury does not dissipate in the environment.

Can you start your own thread and post photos for us, please?

 

Because platings tend to be very thin often expressed in how many MILLIONTHS of and inch or mm thick they are. For example the copper plating on the current US cents is given a 8 microns, that is 8 millionths of a mm thick. This is nothing compared to the relief which is express in so many 10 thousandths of an inch.

 

I also just found a 56 d penny and its silver. What strikes me is that the coin itself is in really good shape. The front has some scratches in it like someone tried to scratch through the surface to see if it is silver through. But the back is in great shape no fading at all. Does anyone have a hypothesis on this?
