    Dear Tom, I don't know what technology the Greeks had. Did they make
    steel? Have bronze metal working tools been recovered? 

    Looking at the coins pictured I would go about working in the
    positive rather than the female part of the die. I would carve in wax
    , to be cast in bronze, a male or positive punch and use it to stamp
    into what would become the actual coin making die. That would be the
    quickest and easiest way to produce. Carving into metal, engraving,
    at the depths these coins are stamped would be very time consuming
    and much more difficult than making a punch to make the die to make
    the coin. Then bits of silver or what ever metal the coin was to be
    made with could be produced by pouring metal into a mold, cooled
    weighed and adjusted for weight by filing  to remove weight or
    remelting and adding more metal, and set onto the die and hit from
    the back with another die or a flat  hammer or chisel. Wax casting is
    an ancient method of production and would be a familiar technique for
    tool production. Sam Patania, Tucson
