    is your rolling mill for sheet or a compound mill with grooves for
    shaping wire? 

    Clean and lube the rollers first. Melt the coin.Pour a rod into a
    charcoal block if you don't have a mould and go from theRe: If you
    need a shaped wire, forge the shape you want - or carve the shape
    into the block before pouring if there are no grooves in your mill.
    Rectangular,square, and if you're good triangular-( because rolling
    out triangular wire without a milled groove in the roller is work..
    particularly if its a heavy gauge you are after,but one silver coin
    isn't going to yield that much length regardless in gauges 4-16)
    wires are the options you have. If you desire round wire it may be
    best to carve a tapered well into an end of a charcoal block first,
    then in the center of that take a heated coat hanger or other round
    long metal thing,and drive it into the charcoal (or firebrick). Pre-
    heat the mould slightly and then pour the metal into the void- When
    working something thin and long take extra precautions because molten
    metal will likely want to take the path of least resistance and miss
    the holeespecially if you don't carve a depression / well first, into
    the soft material you are using for your mould.. if you simply put
    the coin in and repeatedly pass it through a sheet mill you'll get a
    disc that will probably have a slight convex shape.. remeber when
    rolling out the rod to anneal periodically and use draw tongs if you
    have them, or pliers to keep the wire as straight as possible.
    another alternative is to buy rollers for your mill if it will
    accept new or additional rollers. Rosenthal co. in Miami sells a wide
    variety of rollers for mills that accept replacements and
    add-on's,Some mills will never be quite right after removing the
    original rollers and replacing them with rollers not specifically
    made for the mill. so check the mills manufacturer first to see if
    they sell replacements or additional rollers...but for one coin...its
    a big expense. R.E.R. write if you need more info- i'm short on time
    atpresent.
