    Because the heating required would be towards the melting point of silver. Embrittlement problem solved. Coin a blob. Not a good trade off.

    What I do with such coins is ensure they sit on a pad of thick felt or cotton (like the pads used to remove make-up) cut to fit the tray. And be very careful handling them.

    Wide thin silver coins - like Sassanian or Islamic dirhams - are a real pain if embrittled......

    If the value of coin itself was less than the melt value of the silver it contained, then someone might melt it. Are some of those crystallized coins worthless now that they are damaged?

    Silver can oxidize to either the sulfide or the oxide.
