    Janet, you may try copper coating it with old, used, copper filled
    pickle and an iron nail. It's an old plating technique. After it's
    been plated sufficiently, pull it from the pickle, neutralize and
    clean it well without scrubbing off the new copper plating.  Then
    spray it with salt water or vinegar and salt and stick it in a closed
    container with a small container of household ammonia for a while.
    The ammonia fumes will, over a short time, bring out a very nice
    copper patina. You could mask off any areas that you don't want
    plated with melted wax before dropping it into the old pickle. After
    it has fumed to the desired color with the ammonia you can polish off
    the parts you want to be gold and leave the patina where you want it.
    It's just a suggestion. 

Mike
