    Just a shot in the dark here on the first question.

    Copper is cheaper than Silver.

    (thats the same reason that they nickel plate quarters that are made of mostly copper . . . copper is cheap)

    Funny that, the copper coinage in the UK is made of copper plated
    steel, while the silver coinage is still made of a nickel alloy!

    (the intrinsic value of the older copper coins exceeded their face value
    so you were better off selling them for scrap than spending them)
